DIY Drill Safety

Cordless drill drivers are much safer than corded or electric power tools as there is no power lead for you to trip or fall over. Cordless power tools are much more accessible than corded tools as they allow you go anywhere and work in places that would ordinarily be inaccessible due to there being no power plug. Cordless drill drivers are becoming increasingly small and compact in design and are extremely easy to move around and transport. However, the size and weight of a cordless drill driver may vary depending on the battery type. Technological developments have allowed power tool manufacturers to produce cordless drill drivers that have the same voltage and power capacity as electric corded drill drivers.

SDS (Special Direct System) Drills come in two standard sizes and they are SDS Plus (10mm) and SDS-Max (18mm). These sizes relate the size of the shank. SDS Plus is the many common and can withstand a hammer of up to 4Kg, and SDS Max for hammers over 5Kg. SDS Plus grips the drill bit in two places whereas SDS Max grip in three places. With the SDS drill you can use a chuck adaptor that when utilized enables the use of standard drill bits for rotary drilling. It is wise to avoid SDS Drills that do not have a safety clutch. If the drill bit jams and is unable to turn a safety clutch will prevent the drill body from spinning. This spinning can cause severe damage to the wrist and arm with the possibility of the drill being yanked from your hand, jumping out of the hole and coming into contact with a part of the body. A safety clutch should be high on your list of required features.

Any tool should feel like an extension of your hand. The tool may feel great while standing in the store aisle but try to imagine what it will feel like after a few hours of use. While in the shop make sure all controls are convenient, and check to see if the forward/reverse and high/low speed switches in particular are easy to use.

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 many 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.

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

There will be occasions when you have to drill a hole at an angle. In these cases drill carefully. You can draw a pencil line on the material noting the angle and then try to follow that pencil guide as you drill. There are also angle guides you can use. Place these over the spot you want drilled with the guide calibrated at the correct angle. Insert the drill bit into the guide and drill away. If you are drilling completely through the material when the drill bit begins to exit out the other side of the material be careful, especially with wood. The drill bit exiting the wood can splinter the wood around the exit point. If it will show, you might want to sand it smooth. Better yet prevent the splintering by covering the exit point with masking or duct tape. The tape will decrease if not prevent the splintering.

Although not a true 'drill', countersink bits are utilized in a power or hand drill to form the conical recess for the heads of countersunk screws. These bits tend to be made for use on soft materials such as timber and plastics, not metals. When utilized with a power drill to counter sink an existing hole, the bit tends to 'chatter', leaving a rough surface. Better results will be obtained if the countersink bit is utilized before the hole is drilled, then take care to ensure that the hole is in the centre of the countersunk depression. Countersinks are available with fitted handles so that they can be utilized by hand twisting, often easier than changing the bit in the drill when only a relatively few holes need countersinking. Sharpening can be difficult, but can be done with a fine triangular file. Tile bits are those bits utilized for drilling ceramic tiles and glass. They have a ground tungsten carbide tip. They can be utilized with a hand drill, but are best utilized in a variable speed power drill on a slow speed. When drilling glass, some form of lubricant (i.e. turpentine or white spirit) should be utilized to keep the tip cool. Ceramic tiles can also be drilled using a masonry bit if it is utilized at slow speed and without hammer action. Sharpening is difficult because of the hard tungsten carbide and curved cutting edge. With care and patience, a blunt edge can be made good using an oilstone. Intended for power drill use only, the centre point locates the bit and the flat steel on either side cuts away the timber.

DIY Safety tips:

New appliances have to be supplied with a plug that is fused in accordance with manufacturers' instructions. Always follow manufacturers' recommendations for fuses, or seek expert advice. Check older appliances such as electric blankets and Christmas tree lights.
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 plug 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.

Take extra care when removing artex or textured paint from walls as these materials may contain asbestos. Safety precautions must be followed when handling and disposing of asbestos. Contact your local environmental health department for advice.

Take extra care with old paint. Some old paint could give off harmful dust and pose a poisoning hazard if ingested by small children. You must not burn off old paint or rub it down with dry sandpaper or a power sander; you should clean up properly, using a high efficiency industrial vacuum cleaner with heavy duty filters. Have a basic First Aid kit accessible.

Be sure you know the correct way to use all the tools. Many have very sharp blades.
