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. |

SAFETY | |
1. Always wear
safety goggles to protect the eyes. Never operate equipment like this
without eye protection. |
|
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. |
