Be Do-It-Yourself Safe

The very first aspect you might look at when selecting a cordless drill driver might 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 greater 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 made 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 might 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.

Before cordless drill drivers arrived, most drills had pistol grips, where the handle is behind the motor like the handle of a gun. But most of today's cordless models are equipped with a T-handle: The handle base flares to stop hand slippage and accommodate a battery. Because the battery is centered under the weight and bulk of the motor, a T-handle provides better overall balance, particularly in heavier drills. Also, T-handle drills might often get into tighter spaces because your hand is out of the way in the centre of the drill. But for heavy-duty drilling and driving large screws, a pistol grip does let you apply pressure higher up — almost directly behind the bit — allowing you to put more strain on the work.

The chuck is the attachment where the bit is inserted, having jaws that grip the bit. Drills come in 1/4", 3/8", and 1/2" sizes. This measurement is the chuck size and indicates the shaft diameter of the drill bits and accessories that will fit the drill. Chucks can be keyed (the jaws are tightened or loosened with a key) or keyless (the chuck might be tightened or loosened by hand). Keyless chucks offer two major benefits. If you have ever misplaced or lost a chuck key, you already know one of them. A keyless chuck will also allow drill bits to be changed more quickly. A real plus when you need to change from a drill bit to a screwdriver bit repeatedly or should you happen to be wearing gloves on the job. You can change the chuck in some keyless models with only one hand because the shaft locks when the trigger is off. In most models, however, you have to use both hands to turn the chuck in opposite directions. While you're in the store change the bit on different drill drivers to see what style of keyless chuck you prefer.

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 devices they power. Li-ion batteries are lighter than other equivalent secondary batteries, often much lighter.

Unlike Ni-Cd batteries, lithium-ion batteries might be charged early and often. However, should they are not used for a long time, they might be brought to a charge level of around 40% - 60%. Li-ion batteries might 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.

To drill a satisfactory hole in any material, the correct type of drill bit must be used; it must be used correctly and be sharpened as suitable. Many jobs around the house require a hole of some kind to be drilled - whether it is putting up a shelf, building a cabinet or hanging a light fitting. For basic requirements, a set of high-speed steel twist drill bits and some masonry drill bits will probably be sufficient for the average handyman. But for more sophisticated jobs/material, others drill bits will be required - perhaps larger, or made for a specific material/purpose. Good quality drill bits can be expensive, so take care of them, keep them in a case or box should possible, rather than allowing them to roll around loose in a toolbox where the cutting edges may be damaged.

Usually referred to as twist drill bits, twist bits are probably the most 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 most 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 might not be used for drilling metals as they tend to be more brittle and less flexible than HSS drill bits.

DIY Safety tips:

If you need to change a mains fuse, check the correct rating for that circuit - the blown fuse might have been incorrect in the first place. Using a thicker fuse wire than the correct rating is hazardous. Switch off the power and remove the fuse for the relevant circuit before carrying out any work, or inspecting, either it, or the appliances connected to it. Never inspect, or carry out work on, any part of the system with the power on. Make sure that power cannot be inadvertently restored by someone else.
Always use the correct tools for the job. It is worth investing in high quality equipment as this will be safer and will probably do the job faster.

When using a power drill, pick a model that has a plastic non-conducting body. Unplug the drill before fitting parts and remove the chuck key before switching it on. Avoid wearing loose clothing or jewellery, which could get caught in the drill.

RCD's (Residual Current Devices) might 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 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.

Keep the work area tidy. An untidy work environment easily leads to accidents. Offcuts of wallpaper, for example, may be very slippery underfoot. Take care with ladders and access equipment. Make Sure that they are properly erected and stable.
