The variety of cordless drill drivers is now huge, and all mains powered drills have their cordless battery equivalents. 9.6 volt to 14.4 volt drill/drivers might be used as a rotary drill or screwdriver. 12 volt to 18 volt cordless drill drivers can also have a hammer action. 12 and 14.4 volt machines are ok on hammer action for brick but would struggle drilling concrete and other hard masonry, should you need the drill to undertake this type of work then you should look at the 18 volt models that are available. Then there are the 18 volt to 36 volt SDS type of drills. These are made for masonry work, and with a chuck adaptor these might be turned into rotary drill drivers. Also with the SDS type of cordless drill you might get some of them with roto stop which then turns them into a demolition hammer drill.

There are a lot of types of drill available today, rotary drills, drill drivers, hammer drills, SDS drills made for drilling brick, concrete, masonry, metal and wood. You might pick 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 used mainly on building sites, 240 volt tools for home use should be used 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.

The least expensive drill drivers run at a single speed, but many have two fixed speeds: 300 rpm and 800 rpm. A slide switch or trigger lets you select high or low speed. These drill drivers are ideal for many light-duty operations. The low speed is for driving screws, the high speed for drilling holes. For more refined carpentry and repair tasks, pick a drill that has the same two-speed switch and a trigger with variable speed control that lets you vary the speed from 0 rpm to the top of each range. And should you do more hole drilling than screwdriving, look for more speed, 1000 rpm or higher at the top end.

A reversible drill is a must should you plan on using the drill with screwdriver bits. Torque is the term used to describe the rotational pressure exerted by the drill. Today's higher voltage cordless drill drivers may provide nearly the same amount of torque as a corded model. Yes, bigger is better, but increased power almost always brings increased size and weight. Unless you plan on drilling with large self-feeding or auger bits, consider a more compact model with a lower torque. Because there is no industry standard for measuring torque, be aware that you cannot compare the torque ratings of drill drivers from one brand to another.

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 should you have two batteries. What's more, there are drawbacks to fast charging. A fast recharge might damage a battery by generating excessive heat, unless it's a specially made 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 should be charged early and often. However, should they are not used for a long time, they should be brought to a charge level of around 40% - 60%. Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging may 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 may last a lot of 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 may 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 prevented 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 bits and some masonry bits may probably be sufficient for the average handyman. But for more sophisticated jobs/material, others bits may 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.

As the name suggests masonry bits are made for drilling into brick, block, stone, quarry tiles or concrete. The cutting tip is often made from tungsten carbide bonded to a spiralled steel shaft. Some masonry drill bits are described as 'durium tipped', this term refers to a highly durable silicon bronze alloy used instead of tungsten as the cutting point. Masonry bits are usually used in a power drill; although they might be used with a lot of effort in a hand brace. Most masonry bits might be used with a hammer action power drill driver, but always check as the action is quite punishing on the bit and cheaper bits have been known to shatter when subjected to the pounding. Always use a slow rotational speed for drilling into harder materials to avoid overheating the tip and frequently withdraw the bit to remove any dust. Long Masonry bits (300 to 400mm) are available for drilling through masonry walls and bit sizes range from 4 to 16mm. Use a drill sharpener or grindstone to sharpen the tungsten carbide tip.

DIY Safety tips:

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.
When fixing or checking electrical appliances or connections, always switch off the power and remove the fuse or circuit breaker (MCB). If you're fixing an electrical appliance, switch 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 may 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.

Always keep a chemical fire extinguisher in the house. Never use water to put out a fire in an electrical appliance. Gas and electrical work is best left to a registered professional.

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, switch off the appliance at the socket and unplug it before trying to find out why. The same principles apply to fuse boxes or circuit breakers - always switch 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.

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