Cordless Drill Drivers - DIY Tips

More and more companies are producing cordless power tools due to the new technology available. Some of the leading cordless power tool brands are Makita, DeWalt, Hitachi and Bosch. Much of the developments surrounding cordless power drill drivers are to do with the battery packs that cordless power tools need to function. As battery pack, technology has improved over the last few years most manufacturers now offer a wide range of battery packs including Li-Ion, Ni-MH and Ni-Cad packs.

There are numerous types of drill on the market today, rotary drills, drill drivers, hammer drills, SDS drills designed for drilling brick, concrete, masonry, metal and wood. You might select cordless or electric, when choosing an electric drill there are two voltages, 110 and 240. 110 volt power tools need a power tool transformer and are utilized mainly on building sites, 240 volt tools for home use could be utilized with a RCD circuit breaker for safety. Cordless drill drivers give more flexibility due to the fact that you do not have a mains lead to contend with.

Before cordless drill drivers arrived, most drills had pistol grips, where the handle is behind the motor like the handle of a gun. But most of today's cordless models are equipped with a T-handle: The handle base flares to prevent hand slippage and accommodate a battery. Because the battery is centered under the weight and bulk of the motor, a T-handle provides better overall balance, particularly in heavier drills. Also, T-handle drills might often get into tighter spaces because your hand is out of the way in the centre of the drill. But for heavy-duty drilling and driving large screws, a pistol grip does let you apply pressure higher up — almost directly behind the bit — allowing you to put more force on the work.

Drilling softwood, hardwood, metal, and masonry all require different drill speeds. Harder materials or larger bits have to be worked at lower speed. Conversely, softer materials and smaller bits might be utilized at higher speeds. Look for a drill with variable speed. Variable speed allows the user to control the bit speed, indispensable when you plan on working different materials and accessories.

All cordless drill drivers come with a battery charger, with recharge times ranging from 15 minutes to three hours. But faster isn't necessarily better. A contractor might depend on fast recharges, but slower recharging isn't usually a concern at home, especially if you have two batteries. What's more, there are drawbacks to fast charging. A quick recharge might damage a battery by generating excessive heat, unless it's a specially designed unit. If you want a speedy recharge, go with a tool from Makita, Hitachi or Panasonic, whose "smart" chargers are equipped with temperature sensors and feedback circuitry that protect batteries. These units provide a charge in as little as nine minutes without battery damage.

Unlike Ni-Cd batteries, lithium-ion batteries could be charged early and often. However, if they are not utilized for a long time, they could be brought to a charge level of around 40% - 60%. Li-ion batteries could be kept cool. Ideally they are stored in a refrigerator. Aging will take its toll much faster at high temperatures. The high temperatures found in cars cause lithium-ion batteries to degrade rapidly. Storing a Li-ion battery at the correct temperature and charge makes all the difference in maintaining its storage capacity. It is significantly beneficial to avoid storing a lithium-ion battery at full charge. A Li-ion battery stored at 40% charge will last numerous times longer than one stored at 100% charge, particularly at higher temperatures.

When drilling deep or large holes, it is best to drill a small pilot hole first. This is very helpful when drilling deep holes because it's sometimes easier to keep the hole straight with a smaller bit. A larger bit will then normally follow the pilot hole. When drilling larger holes, especially in metal, the pilot hole opens an area in the metal to accommodate the tip of the larger bit so the cutting surfaces might more easily reach the uncut metal. Once you've drilled your hole, you'll probably find a burr on the back surface of your material. This might be removed by lightly drilling the back side of the hole with a larger bit. If the material is thin, such as sheet metal, instead of a burr you may find the material is actually distorted leaving a ragged hole. This be stopped by sandwiching the material between two pieces of wood before you drill the hole. As with all tools, exercise caution, wear safety equipment and learn to use the tools properly.

To drill a satisfactory hole in any material, the correct type of drill bit must be utilized; it must be utilized correctly and be sharpened as appropriate. Many jobs around the house require a hole of some kind to be drilled - whether it is putting up a shelf, building a cabinet or hanging a light fitting. For basic requirements, a set of high-speed steel twist bits and some masonry bits will probably be sufficient for the average handyman. But for more sophisticated jobs/material, others bits will be required - perhaps larger, or designed for a specific material/purpose. Good quality drill bits can be expensive, so take care of them, keep them in a case or box if possible, rather than allowing them to roll around loose in a toolbox where the cutting edges may be damaged.

Although not a true 'drill', countersink bits are utilized in a power or hand drill to form the conical recess for the heads of countersunk screws. These bits tend to be designed for use on soft materials such as timber and plastics, not metals. When utilized with a power drill to counter sink an existing hole, the bit tends to 'chatter', leaving a rough surface. Better results will be obtained if the countersink bit is utilized before the hole is drilled, then take care to ensure that the hole is in the centre of the countersunk depression. Countersinks are available with fitted handles so that they might be utilized by hand twisting, often easier than changing the bit in the drill when only a relatively few holes need countersinking. Sharpening might be difficult, but might be done with a fine triangular file. Tile bits are those bits utilized for drilling ceramic tiles and glass. They have a ground tungsten carbide tip. They might be utilized with a hand drill, but are best utilized in a variable speed power drill on a slow speed. When drilling glass, some form of lubricant (i.e. turpentine or white spirit) could be utilized to keep the tip cool. Ceramic tiles might also be drilled using a masonry bit if it is utilized at slow speed and without hammer action. Sharpening is difficult because of the hard tungsten carbide and curved cutting edge. With care and patience, a blunt edge might be made good using an oilstone. Intended for power drill use only, the centre point locates the bit and the flat steel on either side cuts away the timber.

DIY Safety tips:

If you need to change a mains fuse, check the correct rating for that circuit - the blown fuse might have been incorrect in the first place. Using a thicker fuse wire than the correct rating is hazardous. Switch off the power and remove the fuse for the relevant circuit before carrying out any work, or inspecting, either it, or the appliances connected to it. Never inspect, or carry out work on, any part of the system with the power on. Make sure that power cannot be inadvertently restored by someone else.
Always use the correct tools for the job. It is worth investing in high quality equipment as this will be safer and will probably do the job faster.

Take extra care when removing artex or textured paint from walls as these materials may contain asbestos. Safety precautions must be followed when handling and disposing of asbestos. Contact your local environmental health department for help.

New appliances have to be supplied with a plug that is fused in accordance with manufacturers' instructions. Always follow manufacturers' recommendations for fuses, or seek expert help. Check older appliances such as electric blankets and Christmas tree lights. If a fuse blows for no obvious reason or an appliance is not working properly, turn off the appliance at the plug and unplug it before trying to find out why. The same principles apply to fuse boxes or circuit breakers - always turn off at the mains before you investigate and remember to replace the cover before switching back on. If you need to change a mains fuse, check the correct rating for that circuit - the blown fuse might have been incorrect in the first place. Using a thicker fuse wire than the correct rating is hazardous.

Keep children and pets away from the work area. Store all tools and materials out of their reach. Many products are toxic.
