Hertel F.901.1984 Reduced Shank Drill Bit 25/32 in Hss

Product Description

The HERTEL F.901.1984 is a reduced shank twist drill bit manufactured from high-speed steel with an oxide finish. It is designed for general-purpose drilling in metal, wood, and plastic in shop and field environments. The cutting diameter measures 25/32 inch (0.7812 inches decimal) with a 3/4-inch straight-cylindrical shank that allows it to chuck into standard 3/4-inch capacity drill chucks. The 118-degree split-point geometry is a standard general-purpose angle suited to a broad range of workpiece materials. Licensed machinists, millwrights, pipefitters, and maintenance technicians are the primary users of this bit size.

This drill bit fits standard drill press setups and hand-held power drills equipped with a 3/4-inch chuck. The reduced shank design allows a larger-diameter bit to seat in a smaller chuck, making it practical for job-site drilling where a full-capacity drill press is not available. With a 3-inch flute length and a 6-inch overall length, this bit handles drilling depths up to 3 inches in a single pass. It is appropriate for maintenance and repair operations, structural fabrication, and general metalworking tasks in both residential and commercial settings.

Installation Notes

Installation and use should be performed by qualified machinists, maintenance technicians, or trade professionals familiar with rotating cutting tools. Secure the shank fully in the chuck and verify the bit runs true before beginning a cut. Always power down and de-energize the drill press or disconnect the power tool before changing bits. Eye protection and appropriate work-holding fixtures are required per standard shop safety practice.
