For cordless drill drivers, power is measured in battery voltage. Higher voltage means more torque-spinning strength to beat resistance. Over the last decade, top-end voltage has increased from 9.6 to 18V, but the range of models include 6, 7.2, 9.6, 12, 14.4 and 18V. Today's higher-voltage drill drivers have enough power to bore big holes in framing lumber and flooring. That's impressive muscle. But the trade-off for power is weight. A typical 9.6V drill weighs 3 1/2 lbs, while an 18V model weighs up to 10 lbs.

SDS (Special Direct System) 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 will prevent the drill body from spinning. This spinning might 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.

The least expensive drill drivers run at a single speed, but most have two fixed speeds: 300 rpm and 800 rpm. A slide switch or trigger lets you select high or low speed. These drill drivers are ideal for most light-duty operations. The low speed is for driving screws, the high speed for drilling holes. For more refined carpentry and repair tasks, select a drill that has the same two-speed switch and a trigger with variable speed control that lets you vary the speed from 0 rpm to the top of each range. And should you do more hole drilling than screwdriving, look for more speed, 1000 rpm or higher at the top end.

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

Depending on the choice of material for the anode, cathode, and electrolyte the voltage, capacity, life, and safety of a lithium ion battery might change dramatically. Lithium ion batteries are not to be confused with lithium batteries, the key difference being that lithium batteries are primary batteries containing metallic lithium while lithium-ion batteries are secondary batteries containing an intercalation anode material. Lithium-ion batteries can be formed into a wide variety of shapes and sizes so as to efficiently fill available space in the tools they power. Li-ion batteries are lighter than other equivalent secondary batteries, often much lighter.

Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, should they are not used for a long time, they should be brought to a charge level of around 40% - 60%. Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging will 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 will last numerous times longer than one stored at 100% charge, particularly at higher temperatures.

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.

A drill without a drill bit is useless. A drill bit is the piece at the end of the drill that does the actual drilling. Drill bits come in a wide variety of sizes (diameter) and length. First you have to insert the bit into the drill. The end of the drill’s barrel has an opening. Insert the dull end of the drill bit into this hole. Now you have to tighten the drill bit into this hole so the bit is secure and does not come free. This is accomplished in one of two ways. The most traditional way is to use a chuck key. The chuck key is a small piece of petal shaped in a right angle. One piece of the key fits into the tightening collar around the bit. There is a hole there for that purpose. Then you simply turn the key clockwise tightening the collar over the bit. Turn it clockwise to tighten. Turn it counter-clockwise to loosen the collar and free the bit. When you do this make certain the drill is unplugged from its power source. This is a safety precaution. The second way does not include a chuck key. Instead there are usually two tightening collars. The bit is inserted in the outer most collar. Grasp this collar with one hand holding it steady. With a small bit of power provided by squeezing the trigger the loose collar spins freely and tightens the bit into the collar. If you want to tighten the bit the collar must spin clockwise. If you want to loosen the bit the collar must turn counter-clockwise. The direction of the collar’s spin is determined by moving a switch on the drill usually located close to the trigger. Now your drill is ready to go. You now have the correct bit size and it is securely settled into the drill. You are ready to drill. First make certain the bit is the suitable material for the material you are drilling. Select a bit designed for metal should you are drilling through metal and select a bit designed for wood when drilling through wood. Using the incorrect bit will damage the bit and perhaps not accomplish the task. Using a wood bit on metal often does not penetrate the metal. When you have marked on the material to be drilled where you want the hole mark it with a pencil or marker with a dot or ‘x’. Place the drill bit exactly on the mark, squeeze the drill trigger and give just the slightest push to the drill. Let the drill do the work. Be patient and don’t force the drill bit through the hole. Try to keep the drill as perpendicular to the material as possible.

Screwdriver bits are designed to fit in rechargeable cordless drill drivers. These bits have a hexagonal shank and are ideal for drilling pilot holes but are limited by the low power of these type of screwdrivers and the limited size of small bits available. To sharpen use a drill sharpener, a grindstone jig or an oilstone.

DIY Safety tips:

Keep water away from anything electric. Don't even wash walls without turning off the power at the mains switch. Never be tempted to use a socket, plug or equipment which could still have water in or on it - allowing it to dry could mean the difference between life and death. Read manufacturer's instructions on extension cables - they could overheat should left coiled. Check an extension is suitable for the appliance it is connected to.
Wear protective clothing including safety goggles, gloves and dust mask when working with potentially hazardous materials such as glass or spray paint. It is also advisable to wear a mask when working in a dusty environment e.g. sawing wood or MDF.

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.

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.

Wear safety goggles whenever there may be a danger of flying debris - for example when using power tools.
