The depth 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 may 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, if 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 designed for masonry work, and with a chuck adaptor these may be turned into rotary drill drivers. Also with the SDS type of cordless drill you may get some of them with roto stop which then turns them into a demolition hammer drill.

An SDS (Special Direct System) drill uses 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 force 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 switch 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 many 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 should be high on your list of required features.

Before cordless drill drivers arrived, many drills had pistol grips, where the handle is behind the motor like the handle of a gun. But many of today's cordless models are equipped with a T-handle: The handle base flares to prevent hand slippage and accommodate a battery. Because the battery is centered under the weight and bulk of the motor, a T-handle provides better overall balance, particularly in heavier drills. Also, T-handle drills may often get into tighter spaces because your hand is out of the way in the centre of the drill. But for heavy-duty drilling and driving large screws, a pistol grip does let you apply pressure higher up — almost directly behind the bit — allowing you to put more force on the work.

Accessories for drill drivers include bits for drilling wood, metal, ceramic, glass, and masonry. In addition to bits other accessories include hole saws, screwdriver bits, files, rasps, and sanders.

Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery in which a lithium ion moves between the anode and cathode. The lithium ion moves from the anode to the cathode during discharge and from the cathode to the anode when charging.

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.

An electric or portable (battery powered) drill can be a scary thing. But they aren’t hard to use. The most common drill drivers come in a pistol shape, making them easy to hold and use. The drill has a trigger you squeeze in order to make the drill bit rotate. Sometimes there is also a safety button located on the pistol handle that has to be pressed at the same time you squeeze the trigger in order to make the drill bit rotate. The battery pack is usually inserted into a docking station on the bottom of the pistol handle. Between uses the battery pack is charged in another docking station which is connected to an electrical outlet.

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 may also purchase bit collars that slide over the bit and are secured at the appropriate depth. The collars usually attach with a small hex wrench or screwdriver. The drilling is done 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 force 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 may also purchase bolt sockets that may 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 many common drilling tools used 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 may be used 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 many types of material. When drilling metal the HSS stands up to the high temperatures. Carbon steel bits are specially ground for drilling wood and should not be used for drilling metals as they tend to be more brittle and less flexible than HSS bits.

DIY Safety tips:

Although RCDs are a vital safety aid, they can't guarantee 100% protection. Even with them in your home, isn't it better to make a long term investment in good safety practice by looking after appliances such as hedge cutters, hedge trimmers, chainsaws, drill drivers and sanders. Do not work with electricity in damp or wet conditions. If you MUST, always use an RCD. Always place the cable of a hedge trimmer or mower over your shoulder and keep it behind you at all times.
When painting, or using any material that generates toxic fumes or dust, keep the room well ventilated. Never smoke while painting or standing close to a freshly painted area.

When using a power drill, select a model that has a plastic non-conducting body. Unplug the drill before fitting parts and remove the chuck key before switching it on. Avoid wearing loose clothing or jewellery, which could get caught in the drill.

Do not work with electricity in damp or wet conditions. If you MUST, always use an RCD. Always place the cable of a hedge trimmer or mower over your shoulder and keep it behind you at all times.

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 should always be followed.
