Hertel 84577907 Jobber Drill Bit Letter F Hss 118 Deg

Product Description

The HERTEL 84577907 is a jobber-length drill bit sized to Letter F (0.2570 inches decimal), designed for general-purpose drilling in a wide range of materials. Built from high speed steel with a bright, uncoated finish, it delivers reliable performance in metal, wood, and plastics. The 118-degree standard point angle is the industry-standard geometry for versatile drilling across common workpiece materials. With an overall length of 4.125 inches and a 2.875-inch flute length, this bit fits standard drill chucks and magnetic drill presses used daily in mechanical, electrical, and fabrication trades.

This drill bit is suited for production and maintenance drilling tasks where a general-purpose HSS jobber bit is specified. The straight-cylindrical shank seats directly in 3-jaw chucks on handheld drills, drill presses, and CNC lathes. The regular spiral flute with tapered web and web-thinned point reduces thrust during entry and helps clear chips efficiently. It is a single-unit item, packaged individually for bench stock or toolbox replenishment.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals using standard drill presses, hand drills, or CNC equipment. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant for metal drilling to extend bit life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
