Cleveland C03068 Jobber Drill Bit Letter C Hss 118

Product Description

The CLEVELAND C03068 is a jobber-length drill bit sized to Letter C (0.2420 inches) and manufactured from high speed steel with a bright, uncoated finish. It features a 118-degree standard point angle with web thinning applied to reduce thrust and improve penetration. The fast spiral flute geometry promotes efficient chip evacuation during drilling operations. This bit runs a right-hand cut with a straight-cylindrical shank, making it compatible with standard drill chucks. It is a general-purpose bit suited for machinists, maintenance technicians, and fabricators working across light industrial and shop environments.

The C03068 is designed for drilling aluminum as a primary workpiece material, though its general-purpose HSS construction handles a range of non-hardened metals and plastics encountered in typical shop and field work. With an overall length of 4 inches and a flute length of 2.75 inches, it fits standard drill presses, hand drills, and benchtop equipment without modification. The straight-cylindrical shank diameter of 0.2420 inches seats securely in keyed or keyless chucks. This bit is sold individually and is appropriate for both production drilling and one-off maintenance tasks.
