Doing It Yourself - Safety First

More and more companies are producing cordless power tools due to the new technology available. Some of the leading cordless power tool brands are Makita, DeWalt, Hitachi and Bosch. Much of the developments surrounding cordless power drill drivers are to do with the battery packs that cordless power tools need to function. As battery pack, technology has improved over the last few years most manufacturers now offer a wide range of battery packs including Li-Ion, Ni-MH and Ni-Cad packs.

There are many types of drill available today, rotary drills, drill drivers, hammer drills, SDS drills manufactured for drilling brick, concrete, masonry, metal and wood. You may chose cordless or electric, when choosing an electric drill there are two voltages, 110 and 240. 110 volt power tools need a power tool transformer and are utilized mainly on building sites, 240 volt tools for home use might be utilized with a RCD circuit breaker for safety. Cordless drill drivers give more flexibility due to the fact that you do not have a mains lead to contend with.

An adjustable clutch is what separates electric from cordless drill drivers. Located just behind the chuck, the clutch disengages the drive shaft of the drill, making a clicking sound, when a preset level of resistance is reached. The result is that the motor is still turning, but the screwdriver bit isn't. A clutch provides you control so you don't strip a screw or overdrive it once it's tight. It also helps protect the motor when a lot of resistance is met in driving a screw or tightening a bolt. The number of separate clutch settings varies on the drill; better drill drivers have at least 24 settings. With that many clutch settings, you may really fine-tune the power a drill driver delivers. Settings with the lowest numbers are for small screws, higher numbers are for larger screws. Many clutches also have a drill setting, which allows the motor to drive the bit at full power.

Accessories for drill drivers include bits for drilling wood, metal, ceramic, glass, and masonry. In addition to bits other accessories include hole saws, screwdriver bits, files, rasps, and sanders.

All cordless drill drivers come with a battery charger, with recharge times ranging from 15 minutes to three hours. But faster isn't necessarily better. A contractor might depend on fast recharges, but slower recharging isn't usually a concern at home, especially should you have two batteries. What's more, there are drawbacks to fast charging. A quick recharge may damage a battery by generating excessive heat, unless it's a specially manufactured unit. If you want a speedy recharge, go with a tool from Makita, Hitachi or Panasonic, whose "smart" chargers are equipped with temperature sensors and feedback circuitry that protect batteries. These units provide a charge in as little as nine minutes without battery damage.

Check out drill drivers in DIY centres noting their weight and balance. Try out vertical and horizontal drilling positions to see how comfortable you feel. Contoured grips and rubber cushioning on some models make them very comfortable, even when you're applying direct palm pressure. While you're at it, see how easy it is to change clutch settings and operate the keyless chuck.

When drilling deep or large holes, it is best to drill a small pilot hole first. This is very helpful when drilling deep holes because it's sometimes easier to keep the hole straight with a smaller bit. A larger bit may then normally follow the pilot hole. When drilling larger holes, especially in metal, the pilot hole opens an area in the metal to accommodate the tip of the larger bit so the cutting surfaces may more easily reach the uncut metal. Once you've drilled your hole, you'll probably find a burr on the back surface of your material. This may be removed by lightly drilling the back side of the hole with a larger bit. If the material is thin, such as sheet metal, instead of a burr you may find the material is actually distorted leaving a ragged hole. This be prevented by sandwiching the material between two pieces of wood before you drill the hole. As with all tools, exercise caution, wear safety equipment and learn to use the tools properly.

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 suitable depth. The collars usually attach with a small hex wrench or screwdriver. The drilling is done 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 quick 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 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.

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 might be done 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 might be done 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 might be done 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 might 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:

If a fuse blows for no obvious reason or an appliance is not working properly, switch off the appliance at the plug and unplug it before trying to find out why. If the fault can't be found or you are uncertain how to find the fault, get expert help. The same principles apply to fuse boxes or circuit breakers - always switch off at the mains before you investigate and remember to replace the cover before switching back on.
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: 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 may be a label on the product.

RCD's (Residual Current Devices) may respond to changes 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.

If you have any doubts whatsoever about how to safely use any material, or equipment, ask the manufacturer or supplier.
