How to Use a Unibit

Secure a Unibit into the chuck of a 3/8-inch drill motor. Read the dimensions printed on the drill bit flute (recess.) Mark the appropriately sized step with a wax pencil.

Coat the Unibit with cutting fluid. Apply cutting fluid to the surface you are drilling. Do not coat the Unibit or the material if you are drilling into wood or other porous materials.

Align the tip of the Unibit with the area you are drilling the hole. Pump the trigger of the drill motor to slowly drill into the material. Running the Unibit at a high RPM will cause the drill bit to overheat and lose its cutting edge.

Stop drilling when the marked step of the Unibit drills into the material. Do not push beyond the marked step or the hole size will exceed the desired dimension.

Pull the handle of the drill bit away from the material to remove the drill bit from the drilled hole. Wipe the cutting fluid and drill shavings from the Unibit and the base material with a clean rag.
