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.

The Hammer Drill is not only able to provide a rotary motion but may also apply a small amount of hammer action to the drill bit, as though someone was tapping the back of the drill while the bit was spinning. This enables the drill to work through masonry. A Hammer Drill might typically have the ability to switch the hammer action off and on as required. You might find that motor wattages start around 600w for this type of drill and a good idea is to look at machines with around a 700w motor, these might enable you to drill masonry with up to a 16mm bit. This type of drill is a good all rounder for the home.

Drills come in three distinct handle styles. The most popular cordless models have the T-handle style where the handle is placed close to the middle. The T-handle style distributes the weight for better balance and less wrist strain. Some people still prefer the more traditional pistol-grip style. The third style is the right-angle version, made for use where space is limited.

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 might affect a cordless drill driver's battery charge. The standard time required to charge a battery pack might 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.

Lithium ion batteries are commonly used in consumer electronics and tools such as drill drivers. They are currently one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses for consumer electronics, lithium-ion batteries are growing in popularity for defence, automotive, and aerospace applications due to their high energy density. However certain kinds of mistreatment may cause Li-ion batteries to explode.

Unlike Ni-Cd batteries, lithium-ion batteries may be charged early and often. However, should they are not used for a long time, they may be brought to a charge level of around 40% - 60%. Li-ion batteries may 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 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 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 fast 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 (should 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.

Learning how to sharpen drill bits is cost effective, it better to keep a bit sharp by occasional sharpening rather than waiting until it becomes really blunt. A sharp bit cuts better with less effort whether used in a power or hand drill. A sharp bit might also give a cleaner hole.

DIY Safety tips:

Always unplug an appliance before working on it and always use the correct fuse for the circuit or appliance. Fitting a fuse of incorrect rating is dangerous. As an additional precaution, wear rubber soled shoes. This might provide a measure of insulation between you and the ground.
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 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.

Don't wait until disaster strikes to find your stop-cocks and gate valves. Opening and closing them four times a year might ensure they easily work when you need them to. Don't let a blown fuse leave you in the dark: keep a repair kit close to 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.

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 dangerous.

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.
