1/8" Head Diam, 3/32" Shank Diam, Counterbore Pilot MPN:433-2

A counterbore pilot bit with a 1/8 head diameter and a 3/32 shank diameter is designed to cut the inner edge of a hole while creating an annular groove or shoulder for countersunk screw heads. Its split-ring type design ensures precise alignment when used in combination with drill bits, preventing wobbling or walk-off during cutting operations on wood, plastics, metals, and composite materials. Available in high-speed steel or carbide constructions, these counterbore pilots are suitable for manual or power-driven tools, ideal for prototyping, repair, or production applications in engineering, machining, woodworking, or assembly workshops where consistent hole size and finish is critical.
