Description

The Irwin Unibit #12 is a step drill bit designed for precision drilling. It features a patented single-flute cutting edge for greater control and a true round hole every time.

Constructed from high-speed steel with a black oxide finish, this drill bit is ideal for use on thin materials such as stainless steel, copper, brass, aluminum, plastic, and laminates. It has a 3/8-inch diameter and a 1/4-inch hex shank that prevents slipping in the drill chuck.
