The Vise Grip VGPUN21 Unibit #21 is a high speed steel fractional step drill bit designed to drill and enlarge holes from 13/16 inch up to 1-3/8 inches in a single tool. Its double flute design with stepped geometry improves torque transfer for faster, more accurate drilling in tight spaces and on machined or forged parts.
Chamfered hole steps provide easy press clearance and reduce chatter, allowing for increased feed speeds and cleaner results. The 1/2-inch shank ensures solid chuck engagement, making this step drill a reliable choice for MRO, fabrication, and metalworking applications.
