Another significant aspect to think about is the amount of voltage a cordless drill driver has as the higher the voltage the more speed and torque the drill will have. The speed and torque of a cordless drill driver will 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 will be thus affecting how heavy the drill will be.

Electric rotary drill drivers are designed 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.

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.

Factors such as temperature, the material being drilled, whether the drilling is nonstop or intermittent, and the whether the battery is at full charge or not will affect a cordless drill driver's battery charge. The standard time required to charge a battery pack will vary from one hour to overnight, depending on the type of tool and charger. Recharge when the drop in performance and power is noticeable. Don't wait until the tool quits working to recharge the battery.

Nickel-metal-hydride (NiMH) batteries represent the latest breakthrough in batteries. They're smaller and run longer than standard nickel-cadmium (Nicad) batteries. NiMH batteries also pose less of a hazard when it comes to disposal than Nicads because they don't contain any cadmium, which is highly toxic. Makita, Bosch, Hitachi and DeWalt offer NiMH batteries, and other manufacturers will soon produce these power cells too.

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 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.

Drilling a hole isn't rocket science but it may be quite frustrating should you don't know how to do it. For example, should you try to use a wood auger bit to drill a hole in metal you'll ruin the bit, score the metal and possibly injure yourself in the process. Drilling a hole correctly, however, is something you may easily accomplish with a little practice.

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 undertaken 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 fast 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 drill 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 (should 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.

Screwdriver drill bits are designed to fit in rechargeable cordless drill drivers. These drill 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 drill 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.
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.

Take extra care with old paint. Some old paint could give off harmful dust and pose a poisoning hazard should ingested by small children. You must not burn off old paint or rub it down with dry sandpaper or a power sander; you could clean up properly, using a high efficiency industrial vacuum cleaner with heavy duty filters. Have a basic First Aid kit accessible.

Keep the work area tidy. An untidy work environment easily leads to accidents. Offcuts of wallpaper, for example, may be very slippery underfoot. Take care with ladders and access equipment. Ensure that they are properly erected and stable.
