Cleveland C71271 Jobber Length Drill Bit 6.6 Mm Hss

Product Description

The CLEVELAND C71271 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel (HSS) with an oxide coating for added surface hardness and corrosion resistance, this bit measures 6.6 mm (0.2598 inches) in diameter with an overall length of 3.976 inches and a flute length of 2.48 inches. The 118-degree standard point angle suits the widest range of common materials and is a staple angle for production and maintenance drilling. The web-thinned, tapered web construction reduces thrust at entry and improves chip evacuation. Installed by machinists, maintenance technicians, and trade professionals across HVAC, plumbing, and electrical work, this bit fits any standard drill chuck or drill press.

The C71271 is suited for general-purpose hole-making in light-to-medium industrial and mechanical service applications. Its straight-cylindrical shank seats securely in keyless or keyed chucks. The regular spiral flute and right-hand cut make it compatible with any standard clockwise-rotating drill. This bit is well-suited for maintenance drilling tasks encountered in field service, shop fabrication, and light manufacturing environments where a reliable HSS jobber bit is the standard tool of choice.

Compatibility

Designed as a general-purpose jobber-length drill bit conforming to DIN 338 and ASME B94.11M specifications, compatible with any standard drill press, handheld drill, or drill driver accepting a straight-cylindrical shank.

Installation Notes

Secure the shank fully into the chuck before operation and confirm the bit runs true before drilling. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat buildup. Always wear eye protection and secure the workpiece before drilling. For best results, use consistent feed pressure and avoid forcing the bit through hard material at excessive speed.
