DIY Drill Driver Safety

Up until recently drills were manually driven but technological advancements have led to the development of drill drivers that are powered by an electric motor. For many years these electric power tools have been the most popular and well-utilized tool around home but recently there has become a increasing trend towards cordless drill drivers thanks to the development of battery technologies.

There are many types of drill available today, rotary drills, drill drivers, hammer drills, SDS drills made for drilling brick, concrete, masonry, metal and wood. You can pick 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.

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, pick 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.

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.

Lithium ion batteries are commonly utilized in consumer electronics and tools such as drill drivers. They are currently one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses for consumer electronics, lithium-ion batteries are growing in popularity for defence, automotive, and aerospace applications due to their high energy density. However certain kinds of mistreatment may cause Li-ion batteries to explode.

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 can be hazardous. Some batteries therefore feature an internal safety circuit which may stop charging in this state, and the battery may 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 can be utilized or charged immediately, some Li-ion batteries may provide more energy when brought to room temperature.

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 can 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 can 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 stopped 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 can 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 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 can also purchase bolt sockets that can be attached to the drill. Match the bit size with the bolt, attach the bit to the drill, and screw in the bolt.

With their central point and two spurs, Bullet drills resemble spur point bits, but can be utilized in metal, wood and plastics. Unlike normal twist drills, the twisted flutes are ground away; making a truer, more accurate bit than normal twist bits. They cut a clean hole and cause little damage when they break through the back of the workpiece. Bit sizes range from 1.5 to 13 mm.

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.
When fixing or checking electrical appliances or connections, always switch off the power and remove the fuse or circuit breaker (MCB). If you're fixing an electrical appliance, switch off the appliance at the socket 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 may 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.

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.

RCD's (Residual Current Devices) can 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 socket 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.

Always read the labels on materials to ensure that you know what safety precautions are required and action to be taken in the event of an accident. Many products give off harmful vapours. The recommendations regarding ventilation and/or respiratory protection might always be followed.
