Another 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 may have. The speed and torque of a cordless drill driver may help to determine how easy and fast the drill is to use. Over the years the amount of voltage that these power tools 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 may be thus affecting how heavy the drill may be.

The 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 can 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.

Drills come in three distinct handle styles. The many popular cordless models have the T-handle style where the handle is placed nearby 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, manufactured for use where space is limited.

The chuck is the attachment where the bit is inserted, having jaws that grip the bit. Drills come in 1/4", 3/8", and 1/2" sizes. This measurement is the chuck size and indicates the shaft diameter of the bits and accessories that may fit the drill. Chucks can be keyed (the jaws are tightened or loosened with a key) or keyless (the chuck can be tightened or loosened by hand). Keyless chucks offer two major benefits. If you have ever misplaced or lost a chuck key, you already know one of them. A keyless chuck may also allow bits to be changed more quickly. A real plus when you need to change from a drill bit to a screwdriver bit repeatedly or if you happen to be wearing gloves on the job. You can change the chuck in some keyless models with only one hand because the shaft locks when the trigger is off. In many models, however, you have to use both hands to turn the chuck in opposite directions. While you're in the shop change the bit on different drill drivers to see what style of keyless chuck you prefer.

Lithium ion batteries are commonly used in consumer electronics and tools such as drill drivers. They are currently one of the many 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.

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 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 can 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 can 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 can 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 can 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 can 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.

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 could 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 if 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:

Never overload a plug with too many plugs or adaptors. Don't 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.
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.

Take extra care when removing artex or textured paint from walls as these materials may contain asbestos. Safety precautions must be followed when handling and disposing of asbestos. Contact your local environmental health department for help.

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.

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.
