In the world of cordless drill drivers, power is measured in battery voltage. Higher voltage means more torque-spinning strength to overcome 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 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 utilized 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 may be high on your list of required features.

Any tool may feel like an extension of your hand. The tool may feel great while standing in the store aisle but try to imagine what it will feel like after a few hours of use. While in the shop make sure all controls are convenient, and check to see if the forward/reverse and high/low speed switches in particular are easy to use.

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.

Unlike Ni-Cd batteries, lithium-ion batteries may be charged early and often. However, should they are not utilized for a long time, they may be brought to a charge level of around 40% - 60%. Li-ion batteries may 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 a lot of times longer than one stored at 100% charge, particularly at higher temperatures.

Drilling a hole isn't rocket science but it might 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 might easily accomplish with a little practice.

There will be occasions when you have to drill a hole at an angle. In these cases drill carefully. You might 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 might 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 might splinter the wood around the exit point. If it will 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 will decrease should not prevent the splintering.

Although not a true 'drill', countersink drill bits are utilized in a power or hand drill to form the conical recess for the heads of countersunk screws. These drill bits tend to be designed for use on soft materials such as timber and plastics, not metals. When utilized with a power drill to counter sink an existing hole, the bit tends to 'chatter', leaving a rough surface. Better results will be obtained should the countersink bit is utilized before the hole is drilled, then take care to ensure that the hole is in the centre of the countersunk depression. Countersinks are available with fitted handles so that they might be utilized by hand twisting, often easier than changing the bit in the drill when only a relatively few holes need countersinking. Sharpening might be difficult, but might be done with a fine triangular file. Tile drill bits are those drill bits utilized for drilling ceramic tiles and glass. They have a ground tungsten carbide tip. They might be utilized with a hand drill, but are best utilized in a variable speed power drill on a slow speed. When drilling glass, some form of lubricant (i.e. turpentine or white spirit) may be utilized to keep the tip cool. Ceramic tiles might also be drilled using a masonry bit should it is utilized at slow speed and without hammer action. Sharpening is difficult because of the hard tungsten carbide and curved cutting edge. With care and patience, a blunt edge might be made good using an oilstone. Intended for power drill use only, the centre point locates the bit and the flat steel on either side cuts away the timber.

DIY Safety tips:

If you need to change a mains fuse, check the correct rating for that circuit - the blown fuse might have been incorrect in the first place. Using a thicker fuse wire than the correct rating is dangerous. Switch off the power and remove the fuse for the relevant circuit before carrying out any work, or inspecting, either it, or the appliances connected to it. Never inspect, or carry out work on, any part of the system with the power on. Make sure that power cannot be inadvertently restored by someone else.
When fixing or checking electrical appliances or connections, always turn off the power and remove the fuse or circuit breaker (MCB). If you're fixing an electrical appliance, turn off the appliance at the plug and pull out the plug. Wear rubber-soled shoes when working on electrics. Cover electrical switches which are broken. Switch off at the mains and remove the fuse to that line, and keep it with you, so even should the power is switched on accidentally the line will stay dead and not you, while you carry out a job. The tapes are a reminder for you and a warning to others. Call in professional help should you do not know what you are doing.

Keep your head: should any of your tools has a loose head or handle, replace the whole tool or have it repaired by a professional. Keep a tool box tidy for easy access and always use the cover guards which come with tools such as saws, knives and chisel blades. Buy equipment and household appliances which are made to a British or European standard or carry an approved product quality and safety mark. There will be a label on the product.

RCD's (Residual Current Devices) might respond to alterations in the flow of electric current. For example, when a flex or cable is cut or an electric tool malfunctions, and direct contact is made with a mains supply conductor and earth, the RCD automatically disconnecting the power supply to the equipment to reduce the risk of you being electrocuted. RCD's are available as portable adaptors, can be incorporated in plug outlets, as separate stand alone units for fixed wiring installations offering whole house protection or as modular units for use in household consumer units. However, although RCD's are a vital safety aid, they cannot 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.

Be sure you know the correct way to use all the tools. Many have very sharp blades.
