Safety First

More and more companies are producing cordless power tools due to the new technology available. Some of the leading cordless power tool brands are Makita, DeWalt, Hitachi and Bosch. Much of the developments surrounding cordless power drill drivers are to do with the battery packs that cordless power tools need to function. As battery pack, technology has improved over the last few years many manufacturers now offer a wide range of battery packs including Li-Ion, Ni-MH and Ni-Cad packs.

The Angle Drill is manufactured for use in tight areas. Their main feature is the angled neck. Unlike a conventional drill, an Angle Drills profile allows the drill to be used at arms length and in areas where the body of a drill would not allow it access. While they may not be able to deliver the power and torque of a conventional drill they are incredibly handy tools, especially around the home. An example would be drilling a hole on the inside of a drawer to mount a handle, positioning a normal drill could be awkward but the body of an Angle Drill would rise out of the drawer leaving plenty of space for the operators hand.

An adjustable clutch is what separates electric from cordless drill drivers. Located just behind the chuck, the clutch disengages the drive shaft of the drill, making a clicking sound, when a preset level of resistance is reached. The result is that the motor is still turning, but the screwdriver bit isn't. A clutch provides you control so you don't strip a screw or overdrive it once it's snug. It also helps protect the motor when a lot of resistance is met in driving a screw or tightening a bolt. The number of separate clutch settings varies on the drill; better drill drivers have at least 24 settings. With that many clutch settings, you can really fine-tune the power a drill driver delivers. Settings with the lowest numbers are for small screws, higher numbers are for larger screws. Many clutches also have a drill setting, which allows the motor to drive the bit at full power.

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.

Depending on the choice of material for the anode, cathode, and electrolyte the voltage, capacity, life, and safety of a lithium ion battery can 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.

If a Li-ion battery is stored with too low a charge, there is a risk of allowing the charge to drop below the battery's low-voltage threshold, resulting in an unrecoverable dead battery. Once the charge has dropped to this level, recharging it can be dangerous. Some batteries therefore feature an internal safety circuit which will stop charging in this state, and the battery will be for all practical purposes dead. In circumstances where a second Li-ion battery is available for a given device, it is recommended that the unused battery be discharged to 40% and placed in the refrigerator to prolong its shelf life. While the battery can be used or charged immediately, some Li-ion batteries will provide more energy when brought to room temperature.

Drilling a hole isn't rocket science but it can be quite frustrating should you don't know how to do it. For example, should you try to use a wood auger bit to drill a hole in metal you'll ruin the bit, score the metal and possibly injure yourself in the process. Drilling a hole correctly, however, is something you can easily accomplish with a little practice.

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 many 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 nearby 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 suitable material for the material you are drilling. Select a bit manufactured for metal should 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 pressure the drill bit through the hole. Try to keep the drill as perpendicular to the material as possible.

As the name suggests masonry drill bits are manufactured for drilling into brick, block, stone, quarry tiles or concrete. The cutting tip is often made from tungsten carbide bonded to a spiralled steel shaft. Some masonry drill bits are described as 'durium tipped', this term refers to a highly durable silicon bronze alloy used instead of tungsten as the cutting point. Masonry drill bits are usually used in a power drill; although they can be used with a lot of effort in a hand brace. Most masonry drill bits can be used with a hammer action power drill driver, but always check as the action is quite punishing on the bit and cheaper drill bits have been known to shatter when subjected to the pounding. Always use a slow rotational speed for drilling into harder materials to avoid overheating the tip and frequently withdraw the bit to remove any dust. Long Masonry drill bits (300 to 400mm) are available for drilling through masonry walls and bit sizes range from 4 to 16mm. Use a drill sharpener or grindstone to sharpen the tungsten carbide tip.

DIY Safety tips:

Although RCDs are a vital safety aid, they can't 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. Do not work with electricity in damp or wet conditions. If you MUST, always use an RCD. Always place the cable of a hedge trimmer or mower over your shoulder and keep it behind you at all times.
When painting, or using any material that generates toxic fumes or dust, keep the room well ventilated. Never smoke while painting or standing close to a freshly painted area.

Ladders are one of the main causes of DIY accidents. Erect the ladder according to the manufacturer's instructions. Never lean to one side as you could lose balance. Don't rush as you're more likely to have an accident. Carefully plan the job before you start work. Know your limitations and consult a professional should you are unsure. It's also a good idea to ask someone should they can help you.

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 could clean up properly, using a high efficiency industrial vacuum cleaner with heavy duty filters. Have a basic First Aid kit accessible.

When working in the vacinity of electrical items or cables, make sure the electricity supply is off and the fuse removed . Be sure that others cannot inadvertently re connect the supply.
