Cleveland C71073 Jobber Drill Bit Letter C Hss

Product Description

The CLEVELAND C71073 is a jobber-length drill bit sized to Letter C (0.2420 inches) and built from high speed steel with an oxide coating for surface protection. The bit features a 118-degree standard point angle, a web-thinned tapered web for easier penetration, and a regular spiral flute with right-hand cut. Overall length is 4 inches, with a 2.75-inch flute length and a straight-cylindrical shank. This is a general-purpose drill bit suited for machinists, maintenance technicians, and fabricators working across a wide range of materials.

The C71073 fits standard jobber-length applications in metalworking, maintenance, and light fabrication environments. Its 4xD flute-to-diameter ratio makes it appropriate for through-hole drilling in mild steel, aluminum, and similar materials. The straight-cylindrical shank seats in standard three-jaw drill chucks on both handheld drills and drill presses. It is packaged individually and sold in single-piece quantities.
