Hertel 85703387 Jobber Drill Bit 7/64 in Hss 118 Degree

Product Description

The HERTEL 85703387 is a jobber length drill bit designed for general purpose drilling in metal, wood, and plastics. Built from high speed steel (HSS) with a bright uncoated finish, this bit delivers reliable performance across a wide range of shop and field applications. It features a 118-degree standard point angle, a web-thinned tapered web for easier penetration and reduced thrust, and a right-hand spiral flute configuration. The overall length is 2-5/8 inches with a flute length of 1-1/2 inches, making it a compact and versatile option for machinists, maintenance technicians, and trade professionals working with hand drills or drill presses.

This drill bit is suited for light to medium duty drilling tasks in residential, commercial, and industrial maintenance settings. The 7/64 inch diameter (0.1094 inches decimal) fits standard drill chucks without adapters. Its straight-cylindrical shank seats securely in keyed or keyless chucks. The regular spiral flute geometry promotes consistent chip evacuation, reducing heat buildup during drilling. This bit is typically used by electricians, plumbers, HVAC technicians, and general maintenance personnel who need a reliable, standard-profile HSS bit for everyday hole-making tasks.

Installation Notes

This bit is installed and operated by any trade professional using a hand drill, right-angle drill, or drill press.

Inspect the cutting edges before each use and replace if chipping or dulling is observed.
