Cleveland C71076 Jobber Drill Bit Letter F Hss Oxide

Product Description

The CLEVELAND C71076 is a jobber-length twist drill bit sized to Letter F (0.2570 inches) and manufactured from high speed steel with an oxide coating. It features a 118-degree standard point angle, two spiral flutes with a regular helix, and a straight-cylindrical shank. The web is thinned with a tapered web configuration, which reduces thrust and improves chip evacuation during drilling. This is a general-purpose bit suited for production and maintenance drilling in metal, wood, and plastics. Installation and use are within the scope of machinists, maintenance technicians, and trade professionals working with drill presses, hand drills, or mill setups.

The C71076 is designed for general-purpose drilling applications in both shop and field environments. Its 4-1/8-inch overall length and 2-7/8-inch flute length make it appropriate for standard-depth holes in residential and commercial maintenance, fabrication, and light industrial work. The right-hand cutting direction is compatible with all standard drill chucks and spindles. The oxide finish provides a degree of lubricity and corrosion resistance suitable for dry or lightly lubricated drilling operations.

Installation Notes

Install the bit securely in a properly sized drill chuck, ensuring the shank is fully seated before tightening. Disconnect or de-energize the drilling equipment before changing bits. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life and maintain dimensional accuracy. Follow applicable shop safety standards and wear appropriate PPE including eye protection when drilling.
