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.

An SDS (Special Direct System) drill utilises a unique type of chuck that does not require any tightening. The special SDS drill bits simply slot into place and are held until released. Hammer action is available on SDS type drills, however it is achieved using a slightly different method over the more traditional Hammer Drill. The SDS drill bit moves within the chuck itself rather than the more conventional method of having the whole chuck move. This is due to the way the SDS drill bit is held within the chuck. The SDS drill bit has short grooves running along the length of its body that the chuck clips into. These grooves allow the bit to move in and out and when pressure is applied to the end of the bit within the chuck the bit is forced out slightly creating the hammer action. Some SDS Drills have rotary stop which is able to turn off the rotary action and leave just hammer action allowing the drill to be used as a breaker or demolition hammer with a suitable chisel bit. 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 may prevent 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 could be high on your list of required features.

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 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.

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 may meet 80-90% of your needs. Twelve to 14.4 volt models are the most popular, and they may usually meet most homeowner's work needs. Corded drills are measured in amps. Generally, a higher amperage motor means more power.

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 if you have two batteries. What's more, there are drawbacks to fast charging. A quick recharge may 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.

If a Li-ion battery is stored with too low a charge, there is a risk of allowing the charge to drop below the battery's low-voltage threshold, resulting in an unrecoverable dead battery. Once the charge has dropped to this level, recharging it may be dangerous. Some batteries therefore feature an internal safety circuit which may prevent charging in this state, and the battery may be for all practical purposes dead. In circumstances where a second Li-ion battery is available for a given device, it is recommended that the unused battery be discharged to 40% and placed in the refrigerator to prolong its shelf life. While the battery may be used or charged immediately, some Li-ion batteries may provide more energy when brought to room temperature.

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 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.

There may be occasions when you have to drill a hole at an angle. In these cases drill carefully. You may draw a pencil line on the material noting the angle and then try to follow that pencil guide as you drill. There are also angle guides you may use. Place these over the spot you want drilled with the guide calibrated at the correct angle. Insert the drill bit into the guide and drill away. If you are drilling completely through the material when the drill bit begins to exit out the other side of the material be careful, especially with wood. The drill bit exiting the wood may splinter the wood around the exit point. If it may show, you might want to sand it smooth. Better yet prevent the splintering by covering the exit point with masking or duct tape. The tape may decrease if not prevent the splintering.

Also known as a wood or dowel bit, a spur point bit has a central point and two raised spurs that help keep the bit drilling straight. The bit cuts timber very fast when used in a power drill and leaves a clean sided hole. They are ideal for drilling holes for dowels as the sides of the holes are clean and parallel. Sizes range from 3 to 10mm. Spur point drill bits could only be used for drilling wood or some plastics. Sharpen the point and spurs with a fine file or edge of a fine grindstone; the angle between the point and spurs could be 90°.

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.
Always use the correct tools for the job. It is worth investing in high quality equipment as this may be safer and may probably do the job quicker.

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 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.

Never overload a plug with too many 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.

Only wash with proprietary skin cleaners. Do not use solvents or other chemicals. Do not eat, smoke or drink while handling materials and wash before meals and snacks. Never dispose of chemicals into the drains. Dispose of rubbish carefully. Lay oily rags out flat outside to dry to avoid the possibility of spontaneous combustion.
