One of the first aspect you should examine when purchasing a cordless drill driver should be the battery pack as the more volts your cordless drill driver has the more torque you will get. This essentially means that the motor will spin faster creating greater power. The only drawback with this is that the more volts your drill has the heavier it will be.

Electric rotary drill drivers are manufactured mainly for drilling metal and wood. This type of drill is normally small and compact. Motor sizes range from around 500 watts. The lower wattage motors are ok for drilling small holes or minimal use, the more powerful motored machines will cope with larger size holes and more frequent use. The chuck size is another thing to check, the smaller drill drivers have a chuck which will only accept drill bits up to 10mm diameter the larger chuck size is 13mm.

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 may 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.

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 hazardous. Some batteries therefore feature an internal safety circuit which will prevent charging in this state, and the battery will 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 will provide more energy when brought to room temperature.

For most applications around the house a small set of common twist bits will normally serve your needs. You'll also need a drill to turn the bits and some tools to measure and mark where you want the hole. This includes a ruler or tape measure, a pencil or scribe and should working with metal, a centre punch and a hammer. The first and most important step is marking where you want the hole. You may also use a scribe on wood or plastic. Sometimes even a pencil will work well. As long as you may see your marks and they don't rub off when working your material it doesn't normally matter. Without a punch mark, the bit would drift around. If it did eventually catch, it would quite likely be in the incorrect location.

To drill a satisfactory hole in any material, the correct type of drill bit must be used; it must be used correctly and be sharpened as appropriate. Many jobs around the house require a hole of some kind to be drilled - whether it is putting up a shelf, building a cabinet or hanging a light fitting. For basic requirements, a set of high-speed steel twist bits and some masonry bits will probably be sufficient for the average handyman. But for more sophisticated jobs/material, others bits will be required - perhaps larger, or manufactured for a specific material/purpose. Good quality drill bits can be expensive, so take care of them, keep them in a case or box should possible, rather than allowing them to roll around loose in a toolbox where the cutting edges may be damaged.

Screwdriver bits are manufactured 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 appropriate for the appliance it is connected to.
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.

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.

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.
