Cleveland C71316 Jobber Length Drill Bit 12.5 Mm Hss

Product Description

The CLEVELAND C71316 is a jobber length drill bit designed for general-purpose metal drilling in professional shop and field environments. Built from high speed steel with an oxide coating, it measures 12.5 mm (0.4921 inches) in diameter and 5.945 inches overall length. The 118-degree standard point angle and web-thinned, tapered web design reduce entry force and improve chip clearance at the cut. Two spiral flutes with a regular helix manage chip evacuation efficiently. This bit is installed by machinists, maintenance technicians, pipefitters, and general trade professionals working with drill presses, magnetic base drills, or handheld power tools.

The C71316 is suited for general-purpose drilling in ferrous and non-ferrous metals, plastics, and similar materials in both residential and light commercial maintenance applications. The straight-cylindrical shank fits standard three-jaw chucks without adapters, making it compatible with the widest range of rotary drilling equipment. The 3.976-inch flute length provides adequate reach for most jobber-length drilling tasks, and the 1.969-inch shank length seats securely in standard chucks.

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard three-jaw chucks on drill presses, handheld power drills, and magnetic base drills. Conforms to DIN 338 and ASME B94.11M specifications for jobber series drill bits in the 0.4000 to 0.5000 inch (12.50 to 15.00 mm) size range.

Installation Notes

Secure the straight-cylindrical shank firmly in a properly sized chuck before drilling. Ensure the workpiece is clamped or fixtured to prevent rotation. Apply appropriate cutting fluid for ferrous metals to extend tool life and improve hole quality. Inspect the cutting edges and web for wear or damage before each use and replace the bit if chipping or dulling is observed.
