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

There are a lot of types of drill on the market place today, rotary drills, drill drivers, hammer drills, SDS drills manufactured for drilling brick, concrete, masonry, metal and wood. You might 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 used mainly on building sites, 240 volt tools for home use may be used 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.

Drills come in three distinct handle styles. The most popular cordless models have the T-handle style where the handle is placed close to the middle. The T-handle style distributes the weight for better balance and less wrist strain. Some people still prefer the more traditional pistol-grip style. The third style is the right-angle version, manufactured for use where space is limited.

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 might be used 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.

Depending on the choice of material for the anode, cathode, and electrolyte the voltage, capacity, life, and safety of a lithium ion battery might change dramatically. Lithium ion batteries are not to be confused with lithium batteries, the key difference being that lithium batteries are primary batteries containing metallic lithium while lithium-ion batteries are secondary batteries containing an intercalation anode material. Lithium-ion batteries can be formed into a wide variety of shapes and sizes so as to efficiently fill available space in the appliances they power. Li-ion batteries are lighter than other equivalent secondary batteries, often much lighter.

Unlike Ni-Cd batteries, lithium-ion batteries may be charged early and often. However, if they are not used 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.

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 will 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 might 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 might 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.

A drill without a drill bit is useless. A drill bit is the piece at the end of the drill that does the actual drilling. Drill bits come in a wide variety of sizes (diameter) and length. First you have to insert the bit into the drill. The end of the drill’s barrel has an opening. Insert the dull end of the drill bit into this hole. Now you have to tighten the drill bit into this hole so the bit is secure and does not come free. This is accomplished in one of two ways. The most traditional way is to use a chuck key. The chuck key is a small piece of petal shaped in a right angle. One piece of the key fits into the tightening collar around the bit. There is a hole there for that purpose. Then you simply turn the key clockwise tightening the collar over the bit. Turn it clockwise to tighten. Turn it counter-clockwise to loosen the collar and free the bit. When you do this make certain the drill is unplugged from its power source. This is a safety precaution. The second way does not include a chuck key. Instead there are usually two tightening collars. The bit is inserted in the outer most collar. Grasp this collar with one hand holding it steady. With a small bit of power provided by squeezing the trigger the loose collar spins freely and tightens the bit into the collar. If you want to tighten the bit the collar must spin clockwise. If you want to loosen the bit the collar must turn counter-clockwise. The direction of the collar’s spin is determined by moving a switch on the drill usually located close to the trigger. Now your drill is ready to go. You now have the correct bit size and it is securely settled into the drill. You are ready to drill. First make certain the bit is the appropriate material for the material you are drilling. Select a bit manufactured for metal if you are drilling through metal and select a bit manufactured for wood when drilling through wood. Using the incorrect bit will damage the bit and perhaps not accomplish the task. Using a wood bit on metal often does not penetrate the metal. When you have marked on the material to be drilled where you want the hole mark it with a pencil or marker with a dot or ‘x’. Place the drill bit exactly on the mark, squeeze the drill trigger and give just the slightest push to the drill. Let the drill do the work. Be patient and don’t strain the drill bit through the hole. Try to keep the drill as perpendicular to the material as possible.

With their central point and two spurs, Bullet drills resemble spur point bits, but might be used 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:

Use a voltage tester to check the power to the wires or connections are off before touching them. Check your work thoroughly before restoring power to the circuit. If you are not certain, seek professional advice. Remember the golden rule ... " If you don’t know – ask".
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 if 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 if you do not know what you are doing.

Don't wait until disaster strikes to find your stop-cocks and gate valves. Opening and closing them four times a year will ensure they easily work when you need them to. Don't let a blown fuse leave you in the dark: keep a repair kit close to your mains fuse box, with a torch - check the batteries regularly - screwdrivers, spare fuses, bulbs and fuse wire, rubber gloves and insulated pliers, a trimming knife and insulating tape.

Never overload a socket with too a lot of plugs or adaptors. Do not allow cables and flexes to become kinked or frayed. Make sure plugs are undamaged and tightly closed with no loose connections and that cord grips are tightened. Ensure plugs are correctly fused. Fuses protect cables and flexes from the effects of overheating caused by short circuits and overload.

Keep children and pets away from the work area. Store all tools and materials out of their reach. Many products are toxic.
