HOW TO USE A HAND DRILL

Hand drills must be used carefully - although they are manually operated they can still cause severe injury if misused. It is always a good idea to clamp all material being drilled to a workbench using a clamp such as a G-Clamp. Also, place scrap wood underneath the material being drilled just in case the BIT passes through into the bench top. |
|
The hand drill is held vertically. One hand holds the
handle at the top whilst the second hand rotates the other handle in a
clockwise direction. This turns the chuck and drill bit. Only light
pressure should be used to push down on the hand drill, if a lot of
pressure is needed the drill bit is probably blunt (change it for a
sharp drill bit). |

Tip : When drilling into a material to a certain depth wrap a piece of masking tape around the bit to mark the point at which drilling must stop. |

QUESTION : Imagine you are demonstrating the use of a hand drill for the first time. Write a plan for the demonstration. |
