The variety of cordless drill drivers is now immense, and all mains powered drills have their cordless battery equivalents. 9.6 volt to 14.4 volt drill/drivers can 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 perform 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 manufactured for masonry work, and with a chuck adaptor these can be turned into rotary drill drivers. Also with the SDS type of cordless drill you can get some of them with roto stop which then turns them into a demolition hammer drill.

There are a lot of types of drill on the market today, rotary drills, drill drivers, hammer drills, SDS drills manufactured for drilling brick, concrete, masonry, metal and wood. You can 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.

Any tool should feel like an extension of your hand. The tool may feel great while standing in the store aisle but try to imagine what it may feel like after a few hours of use. While in the shop make sure all controls are convenient, and check to see if the forward/reverse and high/low speed switches in particular are easy to use.

Factors such as temperature, the material being drilled, whether the drilling is nonstop or intermittent, and the whether the battery is at full charge or not may affect a cordless drill driver's battery charge. The standard time required to charge a battery pack may vary from one hour to overnight, depending on the type of tool and charger. Recharge when the drop in performance and power is noticeable. Don't wait until the tool quits working to recharge the battery.

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 may soon produce these power cells too.

Lithium-ion batteries can rupture, ignite, or explode when exposed to high temperature environments, for example in an area that is prone to prolonged direct sunlight. Short-circuiting a Li-ion battery can cause it to ignite or explode, and as such, any attempt to open or modify a Li-ion battery's casing or circuitry is dangerous. Li-ion batteries contain safety appliances that protect the cells inside from abuse, and, should damaged, can cause the battery to ignite or explode.

For most applications around the house a small set of common twist bits may normally serve your needs. You'll also need a drill to turn the bits and some tools to measure and mark where you want the hole. This includes a ruler or tape measure, a pencil or scribe and should working with metal, a centre punch and a hammer. The first and most important step is marking where you want the hole. You can also use a scribe on wood or plastic. Sometimes even a pencil may work well. As long as you can see your marks and they don't rub off when working your material it doesn't normally matter. Without a punch mark, the bit would drift around. If it did eventually catch, it would quite likely be in the wrong location.

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 manufactured 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.

Twist bits are available coated with Titanium nitride (TiN). These are easily identified by the gold like colour. This coating increases the hardness of the bit and adds a self-lubricating property. The coating is only really effective when metal is being drilled, it has little effect when working with other materials. Twist bits are usually available in sizes 0.8-12 mm plus. They are manufactured for drilling relatively small holes and they sometimes tend to clog quickly especially when the wood is 'green'. When drilling deep holes (especially in hardwood) the bits should be withdrawn regularly to remove the waste. Special care is required when using the smallest sizes since these bits are thin and brittle. Always hold the drill square to the work and apply only light pressure when drilling. To sharpen use a drill sharpener, a grindstone jig or an oilstone. Titanium nitride bits cannot be sharpened without destroying the coating (although should the drill needs sharpening, the coating may probably have already been destroyed). Forming the correct angle at the tip is important for efficient cutting.

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.
Store tools in a safe place, out of the way of children and pets. Keep them in a box or a rack. When using knives, always cut away from you. Use a baton as a guide and run a sharp knife along the edge of it. Always store knives securely.

Don't wait until disaster strikes to find your stop-cocks and gate valves. Opening and closing them four times a year may ensure they easily work when you need them to. Don't let a blown fuse leave you in the dark: keep a repair kit nearby your mains fuse box, with a torch - check the batteries regularly - screwdrivers, spare fuses, bulbs and fuse wire, rubber gloves and insulated pliers, a trimming knife and insulating tape.

Take extra care with old paint. Some old paint could give off harmful dust and pose a poisoning hazard should ingested by small children. You must not burn off old paint or rub it down with dry sandpaper or a power sander; you should clean up properly, using a high efficiency industrial vacuum cleaner with heavy duty filters. Have a basic First Aid kit accessible.

When working in the vacinity of electrical items or cables, make sure the electricity supply is off and the fuse removed . Be sure that others cannot inadvertently re connect the supply.
