How to drill a hole

Step 3 Set up

Align and clamp the material in place. Clamps are always a good idea. As the drill pierces through the opposite side of the material, it can grab and spin the work piece. If you are holding the material by hand, injury can result. Be especially careful of this when using a hand drill. If the drill bit grabs, the entire tool can be ripped out of your hands.

If clamps are not available, one can use pliers for holding the object. They usually give better grip to metal than bare naked fingers or gloves do and also lower the danger of injury to the holding hand if the object slips and starts spinning.
