In the world of cordless drill drivers, power is measured in battery voltage. Higher voltage means more torque-spinning strength to beat resistance. Over the last decade, top-end voltage has increased from 9.6 to 18V, but the range of models include 6, 7.2, 9.6, 12, 14.4 and 18V. Today's higher-voltage drill drivers have enough power to bore big holes in framing lumber and flooring. That's impressive muscle. But the trade-off for power is weight. A typical 9.6V drill weighs 3 1/2 lbs, while an 18V model weighs up to 10 lbs.

The Drills come in two standard sizes and they are SDS Plus (10mm) and SDS-Max (18mm). These sizes relate the size of the shank. SDS Plus is the most common and can withstand a hammer of up to 4Kg, and SDS Max for hammers over 5Kg. SDS Plus grips the drill bit in two places whereas SDS Max grip in three places. With the SDS drill you can use a chuck adaptor that when used enables the use of standard drill bits for rotary drilling. It is wise to avoid SDS Drills that do not have a safety clutch. If the drill bit jams and is unable to turn a safety clutch might stop the drill body from spinning. This spinning may cause severe damage to the wrist and arm with the possibility of the drill being yanked from your hand, jumping out of the hole and coming into contact with a part of the body. A safety clutch might be high on your list of required features.

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 stop 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 may 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 strain on the work.

Accessories for drill drivers include drill bits for drilling wood, metal, ceramic, glass, and masonry. In addition to drill bits other accessories include hole saws, screwdriver bits, files, rasps, and sanders.

Nickel-metal-hydride (NiMH) batteries represent the latest breakthrough in batteries. They're smaller and run longer than standard nickel-cadmium (Nicad) batteries. NiMH batteries also pose less of a hazard when it comes to disposal than Nicads because they don't contain any cadmium, which is highly toxic. Makita, Bosch, Hitachi and DeWalt offer NiMH batteries, and other manufacturers might soon produce these power cells too.

Unlike Ni-Cd batteries, lithium-ion batteries might be charged early and often. However, should they are not used for a long time, they might be brought to a charge level of around 40% - 60%. Li-ion batteries might be kept cool. Ideally they are stored in a refrigerator. Aging might 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 might last many 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 might 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 may 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 may 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 used; it must be used 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 drill bits and some masonry drill bits might probably be sufficient for the average handyman. But for more sophisticated jobs/material, others drill bits might be required - perhaps larger, or made for a specific material/purpose. Good quality drill bits can be expensive, so take care of them, keep them in a case or box should possible, rather than allowing them to roll around loose in a toolbox where the cutting edges may be damaged.

Usually referred to as twist drill bits, twist bits are probably the most common drilling tools used by the handyman with either a hand or electric drill. The front edges cut the material and the spirals along the length remove the debris from the hole and tend to keep the bit straight. They may be used on timber, metal, plastics and similar materials. Most twist drill bits are made from either High Speed Steel (HSS) or Carbon Steel. High Speed Steel drill bits are suitable for drilling most types of material. When drilling metal the HSS stands up to the high temperatures. Carbon steel drill bits are specially ground for drilling wood and might not be used for drilling metals as they tend to be more brittle and less flexible than HSS drill bits.

DIY Safety tips:

Keep water away from anything electric. Don't even wash walls without turning off the power at the mains switch. Never be tempted to use a socket, plug or equipment which could still have water in or on it - allowing it to dry could mean the difference between life and death. Read manufacturer's instructions on extension cables - they could overheat should left coiled. Check an extension is appropriate for the appliance it is connected to.
When fixing or checking electrical appliances or connections, always turn off the power and remove the fuse or circuit breaker (MCB). If you're fixing an electrical appliance, turn off the appliance at the socket and pull out the plug. Wear rubber-soled shoes when working on electrics. Cover electrical switches which are broken. Switch off at the mains and remove the fuse to that line, and keep it with you, so even should the power is switched on accidentally the line might stay dead and not you, while you carry out a job. The tapes are a reminder for you and a warning to others. Call in professional help should you do not know what you are doing.

When using a power drill, chose a model that has a plastic non-conducting body. Unplug the drill before fitting parts and remove the chuck key before switching it on. Avoid wearing loose clothing or jewellery, which could get caught in the drill.

RCD's (Residual Current Devices) may respond to alterations in the flow of electric current. For example, when a flex or cable is cut or an electric tool malfunctions, and direct contact is made with a mains supply conductor and earth, the RCD automatically disconnecting the power supply to the equipment to reduce the risk of you being electrocuted. RCD's are available as portable adaptors, can be incorporated in socket outlets, as separate stand alone units for fixed wiring installations offering whole house protection or as modular units for use in household consumer units. However, although RCD's are a vital safety aid, they cannot guarantee 100% protection. Even with them in your home, isn't it better to make a long term investment in good safety practice by looking after appliances such as hedge cutters, hedge trimmers, chainsaws, drill drivers and sanders.

Be sure to double check the safety and condition of any working platform. Make sure that it may not move or give way. Never use ladders on top of working platforms.
