A further vital thing to consider is the amount of voltage a cordless drill driver has as the higher the voltage the more speed and torque the drill might have. The speed and torque of a cordless drill driver might help to determine how easy and speedy the drill is to use. Over the years the amount of voltage that these power appliances have has increased and manufacturers such as Bosch and Hitachi now produce a range of cordless drill drivers including 12v, 14.4v and 18v. What needs to be considered here is that the more voltage the drill has the larger the battery might be thus affecting how heavy the drill might be.

Electric rotary drill drivers are designed mainly for drilling metal and wood. This type of drill is normally small and compact. Motor sizes range from around 500 watts. The lower wattage motors are ok for drilling small holes or minimal use, the more powerful motored machines might cope with larger size holes and more frequent use. The chuck size is another thing to check, the smaller drill drivers have a chuck which might only accept drill bits up to 10mm diameter the larger chuck size is 13mm.

Any tool could feel like an extension of your hand. The tool may feel great while standing in the store aisle but try to imagine what it might 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.

Cordless drill drivers are measured in volts. Drills are available in everything from around 2 volts (for a cordless screwdriver) to the newest 24-volt tools. Higher voltage means heavier weight so consider buying a tool that might meet 80-90% of your needs. Twelve to 14.4 volt models are the most popular, and they might usually meet most homeowner's work needs. Corded drills are measured in amps. Generally, a higher amperage motor means more power.

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.

Check out drill drivers in DIY centres noting their weight and balance. Try out vertical and horizontal drilling positions to see how comfortable you feel. Contoured grips and rubber cushioning on some models make them very comfortable, even when you're applying direct palm pressure. While you're at it, see how easy it is to change clutch settings and operate the keyless chuck.

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 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.

Not all holes need to go all the way through the material. Some holes need only be a certain depth in the wood. The easiest way to make certain you drill the correct depth is to measure the necessary hole depth on your drill bit. Then mark that point on the bit with a marker or wrap some tape around the bit at the measured spot. Then when you drill only insert the drill bit to the mark or tape. You might also purchase bit collars that slide over the bit and are secured at the suitable depth. The collars usually attach with a small hex wrench or screwdriver. The drilling is undertaken and you have to get the bit out. Give the drill a little power to spin the bit and slowly pull it out of the hole. Don’t be too speedy or pull it out without spinning the bit. Either of these may cause the bit to bind in the hole. The hole is complete and now you need to attach the fastener. Bits can be inserted into the drill turning the drill into a screwdriver or wrench. If you are attaching screws determine the size of the screw head and select a matching screwdriver bit. Connect the screwdriver bit to the drill in the same way you would other bits. Put the bit head in the screw head and squeeze the trigger. Be careful not to provide so much power that you go all the way through the material (if that’s not called for) or strain the screw head too far down into the material. It’s easy to get carried away with the power of the drill. If you are attaching a bolt fastener you might also purchase bolt sockets that might be attached to the drill. Match the bit size with the bolt, attach the bit to the drill, and screw in the bolt.

Usually referred to as twist drill bits, twist bits are probably the most common drilling tools utilized 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 might be utilized on timber, metal, plastics and similar materials. Most twist bits are made from either High Speed Steel (HSS) or Carbon Steel. High Speed Steel bits are suitable for drilling most types of material. When drilling metal the HSS stands up to the high temperatures. Carbon steel bits are specially ground for drilling wood and could not be utilized for drilling metals as they tend to be more brittle and less flexible than HSS bits.

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 dangerous. 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.
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 plug 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 if 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 if 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.

Never overload a plug with too numerous plugs or adaptors. Do not allow cables and flexes to become kinked or frayed. Make sure plugs are undamaged and tightly closed with no loose connections and that cord grips are tightened. Ensure plugs are correctly fused. Fuses protect cables and flexes from the effects of overheating caused by short circuits and overload.

Always read the labels on materials to ensure that you know what safety precautions are required and action to be taken in the event of an accident. Many products give off harmful vapours. The recommendations regarding ventilation and/or respiratory protection could always be followed.
