Cleveland C71315 Jobber Length Drill Bit 12.2 Mm Hss

Product Description

The CLEVELAND C71315 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel with an oxide coating for increased wear resistance, it cuts a 12.2 mm (0.4803 inch) diameter hole with a standard 118-degree point angle. The web-thinned, tapered web geometry reduces thrust at entry and helps center the bit without a pilot hole. Overall length is 5.945 inches, with a 3.976-inch spiral flute and a straight-cylindrical shank. Two right-hand spiral flutes clear chips efficiently during drilling. This bit is used by machinists, maintenance technicians, pipefitters, and general tradespeople across industrial and commercial job sites.

The C71315 fits standard drill chucks and magnetic drill press setups. Its 0.4803-inch straight-cylindrical shank seats in any chuck capable of accepting that diameter. The 4xD flute-to-diameter ratio makes it well suited for through-hole drilling in moderate-thickness stock. Conforming to ASME B94.11M and DIN 338 standards, it is a recognized general-purpose size in the 0.4000 to 0.5000 inch diameter range. Sold individually as a single-piece unit.

Compatibility

Designed as a general-purpose jobber-length drill bit in the DIN 338 Series 2001G, compatible with any standard drill chuck accepting a 0.4803-inch straight-cylindrical shank, including benchtop drill presses, magnetic drills, and handheld power drills.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling. Use appropriate cutting fluid when drilling hardened or stainless steel to extend bit life and control heat. Disconnect or de-energize the drill press before changing bits. Follow applicable OSHA machine-guarding requirements when operating drill press equipment.
