Well built drill/driver with above average spec for a 12v product. Feels powerful, and with the two batteries has no problems lasting all day. However it has yet to impress me enough to justify spending over 100. There are many other drill/drivers with 2 batteries coming in well under 100. I would have appreciated a few more driver bits too, one double ended bit is pretty stingey.

The number of cordless drill drivers is now immense, and all mains powered drills have their cordless battery equivalents. 9.6 volt to 14.4 volt drill/drivers may be used as a rotary drill or screwdriver. 12 volt to 18 volt cordless drill drivers can also have a hammer action. 12 and 14.4 volt machines are ok on hammer action for brick but would struggle drilling concrete and other hard masonry, if you need the drill to undertake this type of work then you may look at the 18 volt models that are available. Then there are the 18 volt to 36 volt SDS type of drills. These are designed for masonry work, and with a chuck adaptor these may be turned into rotary drill drivers. Also with the SDS type of cordless drill you may get some of them with roto stop which then turns them into a demolition hammer drill.

There are a lot of types of drill on the market place today, rotary drills, drill drivers, hammer drills, SDS drills designed for drilling brick, concrete, masonry, metal and wood. You may 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.

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 gives you control so you don't strip a screw or overdrive it once it's tight. 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 a lot of clutch settings, you may 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.

Drilling softwood, hardwood, metal, and masonry all require different drill speeds. Harder materials or larger drill bits have to be worked at lower speed. Conversely, softer materials and smaller drill bits may be used at higher speeds. Look for a drill with variable speed. Variable speed allows the user to control the bit speed, indispensable when you plan on working different materials and accessories.

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

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 may be hazardous. Some batteries therefore feature an internal safety circuit which might stop charging in this state, and the battery might 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 may be used or charged immediately, some Li-ion batteries might provide more energy when brought to room temperature.

Drilling a hole isn't rocket science but it may be quite frustrating if you don't know how to do it. For example, if 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 may easily accomplish with a little practice.

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 appropriate. 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 might probably be sufficient for the average handyman. But for more sophisticated jobs/material, others drill bits might be required - perhaps larger, or designed for a specific material/purpose. Good quality drill bits can be expensive, so take care of them, keep them in a case or box if 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 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 may 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:

Use a voltage tester to check the power to the wires or connections are off before touching them. Check your work thoroughly before restoring power to the circuit. If you are not certain, seek professional advice. Remember the golden rule ... " If you don’t know – ask".
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.

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

Always read the labels on materials to ensure that you know what safety precautions are required and action to be taken in the event of an accident. Many products give off harmful vapours. The recommendations regarding ventilation and/or respiratory protection may always be followed.
