Cleveland C71231 Jobber Length Drill Bit 2.6 Mm Hss

Product Description

The CLEVELAND C71231 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with an oxide coating, it resists heat buildup and light corrosion during extended use. The bit measures 2.6 mm (0.1024 inches) in diameter with a 118-degree standard point angle and a regular spiral flute configuration. Overall length is 2.244 inches, and the straight-cylindrical shank matches the 2.6 mm drill diameter at 0.1024 inches. The web-thinned, tapered web design reduces walking and cutting resistance at entry. Licensed machinists, maintenance technicians, and trade professionals across HVAC, plumbing, and electrical work rely on this size for pilot holes, access drilling, and fixture work.

The C71231 is suited for general-purpose bench and hand-drill applications where a standard jobber-length bit is required. The 2-flute, right-hand cut geometry handles a wide range of base materials at conventional feed and speed settings. With a flute length of 1.181 inches and a 4xD flute-to-diameter ratio, it clears chips effectively in shallow to moderate-depth holes. It conforms to ASME B94.11M and DIN 338 standards, making it a recognized metric drill size across industrial and trade applications.

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard 3-jaw drill chucks accepting straight-cylindrical shanks in the 0.1024-inch diameter range, per DIN 338 Series 2001G specifications.

Installation Notes

Installation of this bit requires a drill press, hand drill, or driver with a chuck rated for the 0.1024-inch shank diameter. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use cutting fluid or lubricant when drilling ferrous metals to extend bit life and improve hole finish. Wear appropriate eye protection in accordance with applicable shop safety standards.
