Cordless Drills are extremely popular because they are portable and yet powerful. A rechargeable battery (usually 12v to 18v) supplies the power and lasts for several hours before recharging is necessary. They are safer than corded drills because there is no cord to trip over and the voltage required is quite low compared to the 220v - 240v needed for corded drills. However, all the usual safety measures should be taken when using any drill.
Although using a drill when working up a ladder should be avoided where possible, if this has to be attempted - use a cordless drill as they are lighter and do not have a trailing mains lead. Most cordless drills are powerful enough to drill even tough materials like stone and masonry.

1. Always wear safety goggles to protect the eyes. Never operate equipment like this without eye protection.
2. If a front handle is supplied with the cordless drill - use it as it gives greater control over the drill.
3. The person using the drill should space their feet apart. This helps the person balance and lean into the drill, applying his/her weight safely.
4. Always check that electrical wires or water pipes are not in the area of intended drilling. Drilling through an electrical wire can be extremely dangerous.
5. Always seek instruction / training from an appropriately qualified instructor before using any tools, especially power tools.

The battery can be removed from the drill by pressing the battery release button. It can then be plugged into the charger and left for approximately 3 to 5 hours.

TIP:

If you intend to regularly use your cordless drill for along time, buy a spare battery. This means that as one is being charged the drill can still be used.

A basic cordless drill is shown below. Even basic drills are provided with accessories. A rechargeable battery and charger are also included. The battery will need recharging every 1 to 2 hours of continuous use. Cordless drills usually have a front handle that can be fitted if required. It is strongly recommended that the front handle is fitted as it provides extra support and makes it more likely that the drill will be used safely. If both hands are holding the drill then it is impossible for the user to accidentally place his /her hand in the way of the drill whilst it is in use.

Safety / self-locking chucks are very common. These do not need a chuck key and are used by simply turning the chuck and the barrel by hand, in opposite directions. The drill bit locks in position.
