14.4v Cordless Drill Drivers and Safety

A further significant aspect to consider is the amount of voltage a cordless drill driver has as the higher the voltage the more speed and torque the drill may have. The speed and torque of a cordless drill driver may help to determine how easy and quick the drill is to use. Over the years the amount of voltage that these power appliances have has increased and manufacturers such as Bosch and Hitachi now produce a range of cordless drill drivers including 12v, 14.4v and 18v. What needs to be considered here is that the more voltage the drill has the larger the battery may be thus affecting how heavy the drill may be.

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 may 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 may be high on your list of required features.

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.

Cordless drill drivers are measured in volts. Drills are available in everything from around 2 volts (for a cordless screwdriver) to the newest 24-volt tools. Higher voltage means heavier weight so consider buying a tool that may meet 80-90% of your needs. Twelve to 14.4 volt models are the many popular, and they may usually meet many homeowner's work needs. Corded drills are measured in amps. Generally, a higher amperage motor means more power.

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 may soon produce these power cells too.

Unlike Ni-Cd batteries, lithium-ion batteries may be charged early and often. However, should they are not utilized 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 may 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 may last many times longer than one stored at 100% charge, particularly at higher temperatures.

For many applications around the house a small set of common twist bits may normally serve your needs. You'll also need a drill to turn the bits and some tools to measure and mark where you want the hole. This includes a ruler or tape measure, a pencil or scribe and should working with metal, a centre punch and a hammer. The first and most important step is marking where you want the hole. You can also use a scribe on wood or plastic. Sometimes even a pencil may work well. As long as you can see your marks and they don't rub off when working your material it doesn't normally matter. Without a punch mark, the bit would drift around. If it did eventually catch, it would quite likely be in the incorrect location.

To drill a satisfactory hole in any material, the correct type of drill bit must be utilized; it must be utilized 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 bits and some masonry bits may probably be sufficient for the average handyman. But for more sophisticated jobs/material, others bits may be required - perhaps larger, or manufactured 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.

Learning how to sharpen drill bits is cost effective, it better to keep a bit sharp by occasional sharpening rather than waiting until it becomes really blunt. A sharp bit cuts better with less effort whether utilized in a power or hand drill. A sharp bit may also give a cleaner hole.

DIY Safety tips:

If a fuse blows for no obvious reason or an appliance is not working properly, turn off the appliance at the plug and unplug it before trying to find out why. If the fault can't be found or you are uncertain how to find the fault, get expert advice. The same principles apply to fuse boxes or circuit breakers - always turn off at the mains before you investigate and remember to replace the cover before switching back on.
When fixing or checking electrical appliances or connections, always turn off the power and remove the fuse or circuit breaker (MCB). If you're fixing an electrical appliance, turn 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 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.

When using a power drill, select 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.

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.

Only wash with proprietary skin cleaners. Do not use solvents or other chemicals. Do not eat, smoke or drink while handling materials and wash before meals and snacks. Never dispose of chemicals into the drains. Dispose of rubbish carefully. Lay oily rags out flat outside to dry to avoid the possibility of spontaneous combustion.
