Safety Rules for Using Electrical Drills

Updated February 21, 2017

Electric drills can make short work of any holes for any material. A chuck at the end of the tool holds the drill bit in place. When you pull the trigger, the bit rotates at up to 3000 revolutions per second. Unless the tool is cordless, it will also have a long power cord that is often attached to a wall outlet through an even longer extension cord. All these factors can created safety hazards unless you follow some simple safety tips.

Changing drill bits

When changing bits, always turn off the drill and unplug it to prevent it from accidentally coming on.

What to wear

Always wear safety goggles. They protect the eyes from any particles that fly out during drilling. If you expect a lot of dust, also wear a dust mask.

What not to wear

Avoid loose clothing and loose gloves, as they may get caught in the drill bit. Keep any long cords and extensions away from the drill as well.

Pointing the bit

When attaching the bit to the drill, keep the sharp end pointed away from you. In case of any unexpected problems, the drill moves away from your body and not toward it


Use the key to tighten the drill chuck around the bit. Remove the key from the chuck before drilling, and run the drill for a few seconds to ensure that the bit is centred firmly in the chuck.

Use both hands

Use both hands to keep the drill firmly in place when drilling. Do not force the drill into the hole. Instead guide it gently.
