Reviewing Dewalt's 20V MAX Power Tool Platform

!9#: Reviewing Dewalt's 20V MAX Power Tool Platform

Nipping at the heels of the recent release of their 12V MAX power tool line, Dewalt is introducing another platform of remastered and streamlined cordless power tools. Releasing this September, the 20V MAX line is expected to make a considerable splash (for reasons both good and, perhaps, not so good) with the tool community.

Introducing seven innovated power tools and a worklight, Dewalt's 20V MAX line is complete, comprehensive and focused on operator comfort and convenience. This is where the line is expected to make a positive splash. The tools are lightweight, completely ergonomic, and boast an overall impressive battery life. The redesign of the tools' bodies, similar to that of the 12V MAX line, is totally streamlined and with the addition of a few more LED's, operation remains accurate and precise despite less than ideal working conditions. The tool's are well balanced, simple to use, and with some minor speed and power upgrades, the tools are nothing to shake a stick at.

The 20V MAX line, however, deviating from Dewalt's former emphasis on backwards compatibility, is not compatible with their previous 18V platform. This move, despite the re-badging of the new line as 20 volts, has put more than a handful of users in a funk. They feel a little left behind, a little lost in the shuffle, and although Dewalt insists they will maintain the former 18V platform and continue enhancing it (within the limitations of its stem-style battery design), many Dewalt 18V users don't feel as enthusiastic about the 20V platform.

Additionally, and as formerly indicated, the 20V MAX line does not actually produce 20V of working power. In fact, its power output is no different from Dewalt's previous 18V line. The platform is tagged with 20V (rather than 18V) only to avoid compatibility confusion.

Now, after those technicalities are in the open, lets talk a little more about what, specifically, comes along with these tools.

The DRILL-DRIVER:
Beginning with certainly the most popular type of power tool, Dewalt's 20V drill-driver comes in two slightly different versions. The DCD780C2 compact drill-driver kit (with a 1.5-Ah battery) and the DCD980L2 premium drill-driver kit (with a 3.0-Ah battery, slightly larger than the 1.5). Additionally, the hammerdrill-driver and impact driver also come in these slightly distinct versions, but, I (kind of) digress.

Anyhow, the DCD780C2 compact drill-driver kit boasts a super sleek and compact design ideal for working in tight spaces or for use during extended applications. The tool weighs just a measly 3.4-lbs but despite that compact design, the tool's a high-speed, 2-speed transmission (0-600 / 0-2,000 RPM) ensures the drill-driver still packs a considerable punch. The tool is obviously comfortable to use and simple to operate, and with a heavy-duty 1/2" ratcheting chuck it provides good bit gripping strength as well. The thing has 15 clutch settings and the kit includes two 20V MAX lithium ion batteries, a 30-minute fast charger, belt hook, on-board bit holder, a kit box, and a 3-year limited warranty (on the tool only).

On another hand, the DCD980L2 premium drill-driver kit weighs 5.2-lbs but still produces a surprising amount of power from a sleek and comfortable package. The 3.0-Ah battery life is impressive and the batteries themselves contribute to the overall well balance of the tool (of course, the same is true of the other tools in this line-up). The tool's 3-speed all-metal transmission additionally enhances those long run-times and, through matching the tool's output to each application, the general high-performance of the tool as well. With three integrated LED lights, the tool eliminates shadows while working and because the drill has a heavy-duty ratcheting chuck (with carbide inserts for improved gripping strength) and a high-efficiency motor, the driver's power and performance are always reliable. Max RPM is 0-575 / 0-1,350 / 0-2,000 and the clutch has 22 individual settings. The kit includes a one-hour charger, two 20V MAX batteries, a 360-degree side handle, kit box, a 90-day money back guarantee, a 1-year free service contract, and a 3-year limited warranty (on both the battery and the tool).

HAMMERDRILL-DRIVER
To continue, Dewalt's DCD785C2 compact hammerdrill-driver kit (1.5-Ah), at only 3.5-lbs is similarly compact. Its high-speed, 2-speed transmission boasts 0-600 / 0-2,000 RPM for impressive performance in a variety of applications, and because the tool is ergonomically designed and seriously comfortable to use, its working range is nearly unlimited. Like the above drill-driver, this hammerdrill-driver's heavy-duty 1/2" ratcheting chuck has carbide inserts to ensure better bit gripping strength. The kit includes two 20V MAX batteries, a fast charger, belt hook, bit holder, and kit box and the tool itself (just the tool) comes with a three year limited warranty.

The DCD985L2 premium hammerdrill-driver kit boasts the same battery benefits, the same durable 3-speed transmission, the same super-gripping chuck, three LEDs, and the same high-efficiency motor as the premium drill-driver above (DCD980L2). The thing also weighs just 5.2-lbs, but despite its light weight the tool is durable and appears very well equip to take a real jobsite beating. The thing also features the same ergonomic and power benefits as the above hammerdrill-driver and delivers a max RPM range of 0-575 / 0-1,350 / 0-2,000, and a max BPM is 0-9,775 / 0-22,950 / 0-34,000. The hammer-drill-driver kit additionally offers the same inclusions and and comprehensive warranty as the premium drill-driver kit.

IMPACT DRIVER:
Weighing only 2.8-lbs, Dewalt's DCF885C2 compact 1/4" impact driver kit (1.5-Ah) is ideal for working in tight or awkward spaces. Because the thing weighs so little and boasts that ergonomically advanced body design, this impact driver is extremely comfortable to use. The tool has three integrated LED lights to keep your environment illuminated and its one-handed loading ¼" hex chuck (accepts 1" bit tips) renders the tool as convenient as is it powerful. The thing boasts 2,800 RPM, 3,200 IPM and has a max torque of 1,400-in/lbs (117-ft/lbs). The kit includes two 20V lithium ion battery packs, a fast charger, belt hook, kit box and Dewalt's comprehensive 3-year limited warranty, 90-day guarantee, and 1-year free service contract.

Moving forward, the DCF885L2 1/4" impact driver kit (3.0-Ah) weighs 3.4-lbs and with the same three LED lights and similar ergonomic design, this tool is also ideal for close-quarter applications. The tool is comfortable to operate and maintains big power throughout any degree of working difficulty. The same one-handed loading 1/4" hex chuck (accepts 1" bit tips) enhances the tool's overall convenient operation, and with the same 1,400-in/lbs (117-ft/lbs) of max torque, a no load speed of 2,800 RPM, an impressive 3,200 IPM, and the 3.0-Ah 20V MAX battery power, the tool is aggressively powerful and precise. The tool boasts the same inclusions and comprehensive warranty as the above kit.

ANGLE DRILL:
The DCD740C1 compact angle drill kit (1.5-Ah), of course, is designed to make your awkward moments on the job a little simpler to bear. Where a space is tool small, too tight, or in any other capacity, too awkward, the right angle drill is your go-to pal. This particular model is designed with enviable compactness, and with two speed ranges (0-650 / 0-2,000 RPM) the tool is flexible and powerful enough to be in your corner (pardon the pun) for a huge range of applications. The tool's multi-grip trigger also enhances your overall ergonomics and allow users to comfortably operate the tool in a variety of positions. The tool's front-to-back length is just 4", it weighs only 3.8-lbs, uses a plastic 3/8" ratcheting chuck and includes a 30-minute fast charger, a 20V MAX li-ion battery, a belt hook, 2" Phillips tip bit and a kit box. This tool also includes the comprehensive warranty and guarantee listed above.

RECIPROCATING SAW:
Dewalt's DCS380L1 reciprocating saw kit (3.0-Ah) is a pretty brutal little machine. Despite weighing only 7.35-lbs the tool boasts 0 - 3,000 SPM (strokes per minute).This enhances blade control and, of course, contributes to overall faster, smoother cuts. A 1-1/8" stroke length also produces faster, simpler cuts, and with a pivoting adjustable shoe, users have more control over cut depth and glean a little more life from their blades. The saw's four-position blade clamp allows for tool-free blade changes, flush-cutting and also provides increased positional versatility on the job. The saw means business, but is comfortable to operate and durable throughout rough applications. The thing has an electric brake and includes a fast charger, a 20V MAX Lithium Ion battery, a kit box, and the same fancy warranty (3-years with the above satisfaction guarantee and 1-year service contract).

CIRCULAR SAW:
Furthermore, the DCS391L1 (6-1/2") circular saw kit (3.0-Ah) is, not surprisingly, as powerful as it is compact. The saw's 3,700 RPM motor produces industrial speed and power to cut through the most demanding applications and with a crazy-strong (lightweight) magnesium shoe, the saw also provides long-term accuracy. The tool is perfectly balanced, comfortable to operate, has a 0 - 50-degree bevel capacity and weighs only 8-lbs. The saw has a cut depth of 1-5/8" at 45-degrees and 2-1/4" at 90-degrees. Additionally, the circ saw kit includes a fast-charger, a 20V MAX Lithium Ion battery, 6-1/2" carbide-tipped blade, a kit box and the comprehensive warranty (above).

ROTARY HAMMER:
Dewalt's DCH213L2 3-mode SDS rotary hammer kit (3.0-Ah) is quite unlike other rotary hammers of its class. The thing utilizes SHOCKS Active Vibration Control which both considerably reduces vibration and enhances user control, comfort and productivity during even rigorous use. The tool also provides a 360-degree side handle for optimal control and simpler use during more difficult or awkward applications. The hammer offers 1.7-ft/lbs of impact energy rendering the tool just as powerful as any corded hammer (with the added convenience of cordless technology, of course) and with a variable speed and reversing switch, the tool is versatile and well prepared for a variety of applications. The tool's compact, L-shaped design can still access tight spaces with optimal balance, the thing weighs just 6.4-lbs, offers 0-1,100 RPM, and 0-4,100 BPM. The kit includes a one-hour charger, two batteries, depth rod, a kit box and offers the same comprehensive warranty as the above saw.

WORKLIGHT:
And last, but certainly not least, the worklight. Dewalt's DCL040 worklight delivers a super-bright LED output of 110 Lumens. This ensures your work environments are well lit and shadowless for optimal precision, accuracy and overall productivity. The light also has an integral hook for convenient hands-free use as well as use in multiple placements. The head of the light rotates 120-degrees for for optimal functionality and despite the bright output of the light, the thing produces very little heat ensuring both your safety and comfort on the job while still brightening your work-scapes. The tool weighs just 1-lb and with 11-hours of run-time and the same comprehensive warranty (3-years, 1-year service, 90-day guarantee), the thing has seriously got you covered - or, perhaps, simply enlightened.

Maintaining Your Hand Tools

!9#: Maintaining Your Hand Tools

Maintaining tools is one of those tasks it's very tempting to ignore. But there's nothing more frustrating than trying to use a chisel that won't cut - and nothing more tiring than cutting through a large board with a blunt saw. All too often, perfectly good tools get thrown away and replaced with expensive new ones. This guide tells you when it's practical to reclaim them, what you can do yourself, and where to get it done when you can't.

Sharp tools save you effort, and doing your own sharpening saves you money. The one essential piece of equipment for sharpening cutting tools is an oilstone. A suitable one won't cost a fortune and with care it should last a lifetime.

One of the most popular items to invest in is an oilstone. As the name implies, oilstones were originally just pieces of natural stone - often named after the district in which they occurred, such as Washita or Arkansas.

Although such stones are still available, they are extremely expensive. Most modern oilstones are artificial composites. They are made in different grades but unless you have a lot of sharpening to do the most useful is a combination stone, coarse on one side, fine on the other.

Stones must be used with a lubricant to stop the blade overheating and the stone from clogging. Except with coarse natural stone, where water is the lubricant, use a fine oil, such as a light machine oil. If it is necessary to thin the oil down, use paraffin.

After buying a new stone, steep it in a bath of lubricant and leave it until it absorbs no more oil. And always keep it moist when not in use.

An oilstone won't produce a true edge unless it is flat: avoid localized wear by using the whole surface of the stone, even when you are sharpening narrow bladed tools.

To check whether your stone is flat, lay a steel rule along, then across it. If you see any hollows it needs regrinding or replacing.

To regrind it you need a thick sheet of flat glass - an old car side screen from a breaker's yard is fine - and some carborundum powder. Lay the glass flat and spread it with a paste of the powder and water.

Rub the stone around, checking the surface frequently. Continue until the paste clings evenly to the whole surface, then check again with the steel rule.

To maintain the stone in good order, it's best to keep it in a wooden oilstone box. This will stop dust from contaminating the surface and prevent it from being chipped.

The same applies to taking take of your work wear. Look after and care for your personal protection equipment and it will hopefully look after you.

In summary I believe it is always worth keeping your tools in tip top condition. Spending a little time maintaining your work tools and workwear can save you so much time. Remember people, like my grandfather always used to say measure twice cut once.

Hand Held Power Drills - Choosing the Best Drill For the Job

!9# Hand Held Power Drills - Choosing the Best Drill For the Job

[if ]

[endif]

If you were a professional contractor who used various types of drills on a daily basis throughout the course of your job, you would probably already know what type of drill you need for a specific job. But, what about the person who does not work with drills every day. This person probably knows that a certain job or task requires the use of a drill, but may not be certain about what type of drill is needed. Choosing the right drill can be a daunting task and it's really no surprise with all the types of drills to choose from. You have:

basic drills VSR drills drill/drivers hammer drills impact drivers/wrenches rotary hammer drills right angle drills spade handle drills

Maybe you have already been looking at drills and have other questions such as:

What does VSR mean? What is the difference between SDS and spline drive? How does chuck size matter? What is the difference between keyed and keyless chucks? What is a hex driver? Should I go with a cordless or corded drill? What type of cordless battery is best? What is the clutch used for?

Many years ago, when the first hand held power drills came around, there were not many choices outside of brand names when it came to selecting a power drill. Basically, the drills were all corded, all had keyed chucks, and rotated in only one direction and at one speed. So, the choice was not too difficult. Just pick a brand you like.

Things certainly have changed over the years. There are enough options available today to make a person's head spin. There are even more variations and innovations in the works as I write this. While the scope of this guide will not be able to cover every type of power drill in existence, we are going to try to cover most of the bases. My goal in writing this article is to help those who might be having difficulty deciding which type of drill they need, so let's get started.

The basic corded drill

This is the most basic of hand held power drills. It is a simple electric drill with one speed and one direction. It is mainly good for drilling holes in wood, metal, plastic, and soft metals. It is not the ideal choice of drill to use for applications such as driving screws. Since the speed is not variable and the drill only operates at a higher RPM, you would likely either strip the screw head or snap the head off the screw if you tried. You will not likely find many of these around today as their uses are rather limited.

The VSR drill

VSR stands for "variable speed reversible". These drills come in both corded and cordless versions as will most all the drills we discuss from here on out. The drill speed is varied by the amount of pressure applied to the trigger. The farther the trigger is pulled, the higher the RPM will be. There is also a switch, usually near the trigger which reverses the operation of the drill. As you can imagine, these have distinct advantages over the basic corded drill. In addition to being able to perform all the functions of the basic corded drill, they also have a better suited although still limited ability to drive screws, and small lag bolts. Since the speed is variable, you have the ability to drill into harder material without overheating the bit.

One disadvantage to this type of drill is that trying to maintain a certain RPM with the trigger can be very tricky. It takes a certain knack and some getting used to in order to be able to drive screws consistently without stripping the heads, driving the screw too deep, or snapping off the screw head. The reversible feature allows you to remove screws, drive reverse threaded screws, and back out of stock when your drill bit gets stuck or jammed.

The VSR drill/driver

The VSR drill/driver has all the capabilities of a standard VSR drill with the added bonus of a lower rpm/higher torque setting. Another feature generally found on these drills is an adjustable clutch. These are probably the most common types of everyday use cordless drills you will find on the market today. The big advantage with the low rpm/high torque setting is that now you can drive screws and lag bolts at the low rpm needed without having to try to hold the trigger in a certain position. The adjustable clutch will keep you from driving the screw to deep, stripping the screw head, or breaking off the screw head. The clutch will also prevent reaction torque which happens when a bit jams or a screw bottoms out and the drill tries to twist in the opposite direction. In addition you also get higher torque at the low rpm setting that you miss out on when using a standard VSR drill and higher torque means more screw driving power. These drills generally have a slide switch that you use to switch between the 2 settings. In the high RPM setting, the drill functions exactly like a standard VSR drill. In the low rpm/high torque setting, the drill becomes an effective driver for driving screws and small lag bolts. Some of these drills may have a 3rd intermediate setting that compromises between torque and speed allowing you to better match the speed/torque setting to the application.

The VSR hammer drill/driver

Do you need to drill into concrete, stone, or masonry? If, so, then you would want to consider a hammer drill. This type of drill uses a hammer or pounding action as the drill bit rotates. The pounding action of the bit is what enables these drills to bite into the concrete, stone, or masonry. If you were to try to use a non-hammer type drill, you would have a hard time penetrating the hardened concrete, stone, or masonry and would likely overheat the bit or the bit would become jammed in the material. When drilling into concrete, stone, or masonry you will also want to be sure and use a masonry bit. A masonry bit is specially designed for drilling into these materials. Depending on the material, the drill and the bit used, you can generally expect to be able to effectively drill holes in concrete, stone, or masonry up to around 1/2" in diameter. VSR hammer drill/drivers have all the capabilities of a VSR drill/driver in addition to functioning as a hammer drill at the flip of a switch. Due to their versatility, hammer drill/drivers have become a popular choice among both professional contractors and do-it-yourselfers. Some practical uses would be, drilling holes for inserting concrete anchors or TapCon screws for attaching fixtures such as hand railing or light posts to concrete surfaces or attaching fixtures to concrete, block, stone, or brick walls. One of the most highly and professionally rated hammer drill/drivers on the market today is the DeWalt DC925KA.

Rotary Hammer Drills

Think of a rotary hammer drill as a larger, more powerful version of a hammer drill with an added bonus. It also works like a small jack hammer. These drills are dedicated to the purpose of drilling and chipping into concrete, stone and masonry. They are generally not intended for drilling into wood or other similar materials. Rotary hammer drills use a special bit designed not to slip in the chuck. The most common types are the SDS and spline drive. The type of bit you use will depend on the drill. SDS bits come in several different sizes, so you will need to get the size that matches your drill. If you want to drill many larger diameter holes in concrete or stone, then this is the type of dill you need.

As mentioned, this drill also functions like a small jack hammer. By flipping a switch you can turn off the rotary action, then insert a chisel bit and you're ready to go. While rotary hammer drills aren't going to compete with a full sized jack hammer, they are very useful for many smaller jobs such as removing ceramic and stone tile, removing bricks and blocks from existing wall or floor structures, chipping away unwanted or spilled mortar, chipping the rough edges from concrete, and removing excess concrete from concrete forms or other surfaces.

Traditionally, rotary hammer drills were all of the corded variety since cordless batteries were not able to supply the power needed to operate a rotary hammer drill. However, all that is changing with advancements in lithium-ion batteries and power tool design technology. The popularity of cordless rotary hammer drills is growing rapidly. Some cordless rotary hammer drills rival, and may even surpass the performance of their corded counterparts. One such example is the Bosch 11536VSR which in an HGTVpro power tool review was found to drill 1/2" holes in concrete faster than the tool's corded counterpart.

Impact Drivers/Wrenches

Impact drivers are quickly becoming a hot item among contractors and do-it-yourselfers and with all the added benefits of an impact driver, it's no wonder. If you drive a lot of long screws, lag bolts, or have a lot of nuts and bolts you want to assemble quickly and easily, then an impact driver is for you.

The impact driver functions as a standard VSR drill until the time when extra torque is needed. That's when the impact action kicks in. Don't confuse this with the hammer action of a hammer drill. The difference is that a hammer drill "hammers" on the bit in a lateral direction along the length of the bit as it rotates where an impact driver impacts the chuck of the drill in a rotational direction. The result is a huge increase in torque. The impact action also causes the screw bit to grab the screw resulting in less slippage, reducing the possibility of stripping the screw head. As an added bonus the amount of force the operator needs to apply to the drill in order to keep the screw bit from slipping is significantly reduced resulting in less user fatigue.

Impact drivers have a quick change bit holder designed for accepting hex shank bits which are now common among screw bits and many other drill bits and socket driver bits. This style bit holder really makes changing between bits a snap. This bit holder is the main difference between an impact driver and impact wrench. An impact wrench has a square drive for accepting either 3/8" or 1/2" drive sockets depending on the model of impact wrench.

Impact drivers and wrenches also have a size advantage delivering as much as 4 times as much torque as a comparable size VSR drill. This means that a smaller size tool can be used for a particular job which further reduces user fatigue, especially when working overhead. The small size also gives you the ability to work in tighter spaces and if the impact driver uses lithium-ion technology, then the tool weight is even further reduced.

There is one particular impact driver that stands out. In a tool test by Tools of the Trade Magazine, out of 9 top of the line cordless impact drivers, the Milwaukee 9081-22 was able to outrun the group when pushed to the max. This tool sent 48 4" long Timberlock screws into the stock before a noticeable battery slowdown was observed. Timberlock screws are a long screw with a hex head. They are commonly used in outdoor applications such as landscaping, fence and deck building because they require no pre-drilling. Just think of the time you could save when armed with an impact driver and screws that require no pre-drilling.

Right Angle Drills

Right angle drills, as the name implies, have the chuck positioned at a right angle to the body of the drill. Right angle drills are able to drill in tight spaces where other drills just won't reach such as in between two closely positioned wall studs which makes these drills particularly useful for plumbers and electricians.

These drills come in both corded and cordless varieties as well as a wide range of sizes. The smaller size right angle drills are suitable for small to medium jobs in pine and other soft material. The heavy duty models can handle much larger jobs in harder material such as thick oak. One thing you should be aware of when using the more powerful heavy duty models is reaction torque. Due to the design of right angle drills, if the bit should get stuck, the entire drill body will rotate around the chuck potentially causing injury. It's generally a good idea to brace the drill against a floor, wall, or stud. Some models have a built in torque limiter or clutch to help prevent this occurrence. One such model which has a built in torque limiter is the Makita DA4031 [http://www.thetoolspot.us/Products/Makita/Makita-DA4031/MAKITA-DA4031.html]. This heavy-duty right angle drill was also the overall winner in a Tools of the Trade test of several top of the line right angle drills.

Spade Handle Drills

When spade handle drills are mentioned, one might likely think of mixing drywall compound. The mixing of drywall compound or similar substances is one of the most commonly used applications of spade handle drills. These drills are designed with a low rpm, high torque setting that is well suited for mixing drywall mud. Special drywall mixer attachments can be inserted into the chuck for this purpose.

While these drills are very suitable for mixing drywall mud and other similar substances which require mixing, this is certainly not the only use for this type of drill. The aggressive torque these drills produce make them ideal for boring large holes in wood and other materials using spade bits, auger bits or hole saws up to as large as 5" in diameter.

Many of these drills have a rocker or similar type of switch for rapid switching between forward and reverse which aids in backing out jammed bits as well as mixing drywall mud. In addition, these drills generally have an auxiliary side handle as well as a spade handle to aid in tool control.

Questions and answers pertaining to power drills.

What does VSR mean?

VSR stands for variable speed reversible. Drills with this feature are able to operate in both forward and reverse rotation and at variable speeds. Most likely the drill will have a switch or button for switching the rotation from forward to reverse. Generally the speed varies in relation to to how far the trigger is pulled.

What is the difference between SDS and spline drive?

SDS and spline drive refer to two types of bit technology used in rotary hammer drills. There is really no difference in the performance of the two types, so the one you choose will simply be a matter of which type your particular rotary hammer drill requires. There are different sizes of SDS bits which include SDS, SDS+, and SDSmax. Smaller rotary hammer drills will use SDS or SDS+ bits where the larger rotary hammer drills will use SDSmax or spline drive bits. As the name implies, spline drive bits have a splined shaft, while SDS bits have concave recesses in the shaft.

Why does chuck size matter?

Chuck size basically determines what size drill bit you can use based on the size of the drill bit shank. With the exception of rotary hammer drills and impact drivers/wrenches which use a special type of chuck, most typical hand held drills come with either a 3/8" or 1/2" chuck. Most of your smaller drills will use a 3/8" chuck while the heavy-duty models typically use a 1/2" chuck. You cannot put a drill bit with a 1/2" shank in a 3/8" chuck, but you can put a bit with a 3/8" shank in a 1/2" chuck.

What is the difference between keyed and keyless chucks?

Years ago, all hand held drills used keyed chucks. In order to tighten the chuck down on the drill bit, you would use a small tool called a chuck key. Most 3/8" chucks and many 1/2" chucks today are now of the keyless variety. Keyless chucks, as the name implies, do not use a chuck key. Instead the chuck is designed so that a person can easily tighten the chuck down on the bit by hand. While keyless chucks are faster and easier to use, they cannot clamp down onto the bit as tight and therefore do not have the same holding power as a keyed chuck. This lack of holding power can potentially cause round shank bits to slip in the chuck. This is why you will still find many heavy-duty high torque drills using keyed chucks.

What is a hex driver?

A hex driver is just another name for an impact driver. Hex refers to the type of bit holder the drill uses. These drills use a hex shank bit designed not to slip in the holder. This type of bit holder also makes changing bits a snap. Impact wrenches, on the other hand use a square drive for accepting either 3/8" or 1/2" drive sockets.

Should I go with a cordless or corded drill?

This can be a difficult decision for some. The industry trend is ever going more and more towards cordless technology. The very first cordless drills on the market left much to be desired in both power and run time. Over the years cordless technology improved to the point where many cordless tools now compete with and even in many cases out perform their corded counterparts. With power and performance becoming near equal, the choice basically comes down to price. Are you willing to save some money and deal with the inconveniences of dragging power cords around, or would you rather spend a little more and have complete freedom of movement? The choice is yours.

What type of cordless battery is best?

The power tool industry is currently trending toward lithium-ion battery technology. With all the benefits of lithium-ion it is easy to see why. If you compare lithium-ion batteries to nickel cadmium batteries, lithium-ion charges faster, runs longer, maintains longer constant power output, weighs less and stores a charge longer. The disadvantage is that Lithium-ion costs more. However, the difference in price may not outweigh the advantages you get in performance and charge holding time.

What is the clutch used for?

Most drill/drivers and hammer drills have an adjustable clutch. The clutch is typically used when driving screws, nuts, or lag bolts. The clutch is designed so that once a certain required amount of torque is reached, the clutch will engage and cause the rotation of the chuck to slip and stop rotating. There are several reasons for this. One, you won't strip the screw head when the bit keeps turning. Two, you won't drive the screw too deep. Three, reaction torque when the screw or nut bottoms out won't twist your wrist. Many drills produce enough reaction torque to cause bodily harm if the clutch is not used. Many heavy-duty drills capable of producing high amounts of reaction torque have either a non-adjustable built in clutch or a built in torque limiter. An finally, the clutch protects the drill motor from damage.

The Perfect Fastener for Drywall

Over the past decades, the innovation of drywall has replaced the use of traditional brick and mortar in many constructions of office buildings and houses. Drywall is sturdy panels made of paper and plaster (gypsum plaster) that are commonly used to create walls and ceilings. They are made by placing the plaster paste between two sheets of hard papers and later compressed. With so, many buildings and houses are constructed faster, quicker and more conveniently.

However, the drywall must be fastened to a wooden or metal frame in order to be sturdy. Unlike the ordinary walls and woods, the drywall can only be fastened using the specially designed 'drywall screws'. This is because the sharp point of the screws makes it easier to puncture through the walls and give perfect hold between the wall and the frame. The use of the screws differs in accordance with the type of frame you are attaching the drywall to. If you are attaching or fastening to a wooden frame, you should use the Fine Drywall Screw which has wider spacing thread. If you are attaching or fastening to a metal frame, then, you should use the Course Drywall Screw which has narrower thread spacing. This is because the wooden frame has softer substance (when compared to the harder-surfaced metal frame), so it can be easily penetrated as well as fastened perfectly using the broader thread spacing screws. In fact, the broader thread spacing screws give a stronger and fuller holds.

When you are purchasing the screws, it is also important that you consider the diameter and the size of the screws. This is because a too small diameter or short threads of the screws will give weak supports whereas a too large diameter one will cause the walls to break and damage. So, if you are unsure as to which to choose, always remember to seek assistance from the shop assistants.

Having selecting and buying the correct drywall screws, you will need to understand the tips and tricks on how to fasten the screws to the walls. By adhering to the simple steps below, you will be able to fasten the drywall to the metal or wooden frame perfectly:

(i) Use a pencil to plot position for the screw

(ii) Attach the appropriate drill bit to the drill

(iii) Place the drywall screw with sufficient space from the edge of the drywall

(iv) Dig the screw's tip firmly onto place where you would it to be inserted

(v) Begin the drill with slow speed and later at increasing speed

(vi) Stop drilling when the drywall screw has penetrated into the frame

What is a hard metal drill bit?

Every time a post-installed concrete anchors used to fasten a fixture on the hardened concrete, a hole must be drilled in concrete. A popular type of drill, drill the hardened concrete, the drill SDS carbide. SDS is the easy bit retention system '- or what will be the tip in place. There is some debate about what the "SDS" is going to stand. The interpretation of the original German was "push-turn-based" meansStay-Put Twist. Developed time, came as a drive slot must be known or drive shaft slot. The SDS Carbide Drill is a drill designed for drilling in masonry cement. But unlike ordinary bits, SDS drill offers a longer life. These are durable carbide masonry bit to drill the rigors of his butt making it harder and resistant to extreme loads.
As a carbide drill is done?

The SDS drill is toof 5 parts.

1 First, there is the tree, two pairs of slots (for a total of four channels), which is fit in the drill collar. The smaller the grooves are two slots that are not open at the end and prevent the bit from falling out. The larger of the two grooves are grooves, which extend until the end of the tree, and when stuck in the drill bit SDS for leading a positive rotation. This series of grooves can push something in the food, the improvement in drilling torquehammers and power of the instrument.

2 The next component of the SDS-bits is the land - the collection of the spiral (similar to the ridge or peak of a wave).

3 The third area is the flute or the section through the spiral. The recorder facilitates the removal of cement dust as the hole is drilled.

4 The last two components are the head of the SDS bits and carbide drill, which work together to break the concrete. The carbide is welded to the headto the top of the SDS bits harden the breaking of concrete support.

Since this type of drill is used?

SDS bits are designed for use with a hammer. The SDS-bit is added to the end of the drill is in position by turning the spindle of the drill, however, the block of bits in the collar. SDS masonry drill tip is not set in the lining of the drill is held, slide up and down like a piston. The cracks in the well of the SDS bits accept the ball bearings in twospring spindle of the drill and will remain locked until the user is disabled.

The drill should only be used in place of hammering and rotation when using a concrete drill bit SDS. The bit is at the same time and rotate back and forth at the same time. When the trigger is pulled the hammer drill, a crankshaft driven gear moves a piston back and forth in the pneumatic chamber. The compressed air in the chamber, the SDS carbide pushes forward slightly,provides a tangible impact damage. Using an SDS hammer drill can drill in a drill a "hole diameter, 4" 3 / 4 deep, in about 30 seconds.

A good degree of toe in concrete SDS-ride without too much effort on your part. In most drilling applications push harder on the drill will speed up the process. This is not the case with a hammer percussion drill bits. The SDS-bit is actually round and turning at the same time. Pressing on the drillonly slow down your progress and lead to slightly deteriorate fast.
When you need an SDS-carbide bits are used?

The SDS Carbide Drill is used for two reasons. The first is to drill holes in concrete, brick or concrete blocks for the installation of a closure. The second is to drill holes in concrete, bricks or blocks to create a path for the installation of pipes and plumbing.

When using a drill Carbide SDS Drill into the wall, it is important to support the weight of the hammerthe drill. If the drill does not get the right support, the same bit to pay a portion of the weight. This can cause excessive pressure on the pipe can cause the tip to break into the hole.

It 'important not to drill a hole deeper than the predicted depth of the bit. This could lead to a disruption in the dust and increase the amount of heat to the tip of hard metal. Accumulation of heat in the metal can dissolve the hard welding, so that the carbideMoving plate. This could lead to some 'otherwise breaking the concrete.
Some tips to increase the life of your drill SDS:

* Prior to drilling, to see that the carbide drill is in good shape.

* Check the link to ensure that there is no excessive wear. This prevents the drill do not put in the feed.

* Lubricate the tip of the bit to push the connecting shank bit 'in the spindle. This is done by applying asmall amount of fat, the grooves of the tree (no more than a quarter of an inch blob).

* Let the tool do the work. If a quality drill used to drill into the concrete SDS-cut with relative ease. Keep the drill level and pressure evenly over the entire process of drilling.

The stem is the root SDS most commonly used when drilling in concrete. The hammer shank SDS offers excellent performance, high torque transmission and the ease of one hand, fastLocking.

Remember to keep, with all the assembly work for the security in mind. Always follow the safety instructions on all instruments and refer to the manufacturer's instructions for installation, if available, and always remember to wear safety glasses!
