DIY Safety Advice

In the world of 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.

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 may 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 may only accept drill bits up to 10mm diameter the larger chuck size is 13mm.

Any tool should feel like an extension of your hand. The tool may feel great while standing in the store aisle but try to imagine what it may 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.

Drilling softwood, hardwood, metal, and masonry all require different drill speeds. Harder materials or larger bits have to be worked at lower speed. Conversely, softer materials and smaller bits may be utilized at higher speeds. Look for a drill with variable speed. Variable speed allows the user to control the bit speed, indispensable when you plan on working different materials and accessories.

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 may soon produce these power cells too.

Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, if they are not utilized 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 may 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 may last many times longer than one stored at 100% charge, particularly at higher temperatures.

Drilling a hole isn't rocket science but it may be quite frustrating if you don't know how to do it. For example, if 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.

There may be occasions when you have to drill a hole at an angle. In these cases drill carefully. You may 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 may 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 may 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.

Used for cutting large, fixed, diameter holes in wood or plastic a hole saw may usually cut up to a depth of 18mm though deeper versions are available. Best utilized in a power drill at low speed as the blade saws its way through the material. Sharpening should be undertaken with a fine triangular file - as for an ordinary saw. Like the Hole Saw above, combination saws may cut large holes but they consist of a number of different sized round saw blades, usually ranging from about 25 to 62mm in diameter. Normally the blade are secures by a radial screw in the 'head' with all blades other than the desired sized being removed before the screw is inserted to secure the required diameter blade. Best utilized in a power drill at low speed as the blade saws it's way through the material. Sharpening should be undertaken with a fine triangular file and 'setter' as for an ordinary saw. Forstner bits are utilized to form holes with a flat bottom, such as for kitchen cupboard hinges. Best utilized in a power drill held in a drill stand as there's little in the way of a central point. If utilized freehand, the positioning is difficult to control as there is no central pilot bit. Sharpening of the bit should be undertaken on an oilstone or with a fine file. A Wood Auger bit is ideal when drilling large-diameter, deep holes in wood or thick man-made boards. Generally an Auger bit should only be utilized in a hand brace. The bit may cut a clean and deep, flat bottomed holes. The single spur cuts and defines the edge of the hole while the chisel-like cutting edge removes the waste within the previously cut circle. The threaded centre bites into the wood and pulls the bit into the timber. This 'pulling' action means that the bit is really unsuitable for use in a power drill.

DIY Safety tips:

Although RCDs are a vital safety aid, they can't 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. 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 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.

Keep your head: if 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 may be a label on the product.

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.
