Doing it safely yourself!
One of the initial thing you may examine when selecting a cordless drill driver may be the battery pack as the more volts your cordless drill driver has the more torque you will get. This essentially means that the motor will spin faster creating more power. The only drawback with this is that the more volts your drill has the heavier it will be.
There are a lot of types of drill on the market today, rotary drills, drill drivers, hammer drills, SDS drills manufactured for drilling brick, concrete, masonry, metal and wood. You might 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 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 many popular cordless models have the T-handle style where the handle is placed nearby 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 at a premium.
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.
Lithium-ion batteries might rupture, ignite, or explode when exposed to high temperature environments, for example in an area that is prone to prolonged direct sunlight. Short-circuiting a Li-ion battery might cause it to ignite or explode, and as such, any attempt to open or modify a Li-ion battery's casing or circuitry is dangerous. Li-ion batteries contain safety devices that protect the cells inside from abuse, and, should damaged, might cause the battery to ignite or explode.
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 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 might 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 drill 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 might also purchase bolt sockets that might be attached to the drill. Match the bit size with the bolt, attach the bit to the drill, and screw in the bolt.
Usually referred to as twist drill bits, twist bits are probably the many common drilling tools used by the handyman with either a hand or electric drill. The front edges cut the material and the spirals along the length remove the debris from the hole and tend to keep the bit straight. They might be used on timber, metal, plastics and similar materials. Most twist drill bits are made from either High Speed Steel (HSS) or Carbon Steel. High Speed Steel drill bits are suitable for drilling many types of material. When drilling metal the HSS stands up to the high temperatures. Carbon steel drill bits are specially ground for drilling wood and may not be used for drilling metals as they tend to be more brittle and less flexible than HSS drill bits.
DIY Safety tips:
Always unplug an appliance before working on it and always use the correct fuse for the circuit or appliance. Fitting a fuse of incorrect rating is dangerous. As an additional precaution, wear rubber soled shoes. This will provide a measure of insulation between you and the ground.
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.
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 nearby 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.
Take extra care with old paint. Some old paint could give off harmful dust and pose a poisoning hazard should ingested by small children. You must not burn off old paint or rub it down with dry sandpaper or a power sander; you may clean up properly, using a high efficiency industrial vacuum cleaner with heavy duty filters. Have a basic First Aid kit accessible.
Wear safety goggles whenever there may be a danger of flying debris - for example when using power tools.
