Steps
-
Always follow the manufacturer's directions when using a power drill. Safety glasses are advised when drilling in friable matter.
-
Step 1
Insert a drill bit
Insert the chuck key into the small hole on the side of the chuck and turn it counterclockwise until the chuck can accommodate the drill bit. Slide a bit into the chuck.
-
Turn off the power to the drill when fitting or removing a bit.
-
Step 2
Secure the bit
Turn the key in a clockwise direction to tighten the chuck. Make sure the bit is secured tightly.
-
Step 3
Mark the drilling position
Mark the position where you intend to drill. Use a hammer and nail punch to produce a small indentation at that point. This will prevent the drill from slipping.
-
Step 4
Start drilling
Turn on the power to the drill. Position the tip of the drill bit in the indentation, and start drilling at a low speed. Increase the speed of the drill gradually.
-
Keep both hands on the drill as you apply pressure to the trigger. Keep the drill perpendicular to the object you are drilling into.
-
Step 5
Remove the drill
Stop the drill when you have drilled to your desired depth. Remove the drill bit from the hole with the bit rotating at a slow speed.
