Hertel 85703999 Jobber Length Drill Bit Wire 22 Hss

Product Description

The HERTEL 85703999 is a jobber length drill bit designed for general-purpose drilling in metal, wood, plastic, and similar materials. Manufactured from high speed steel with a bright uncoated finish, this bit holds an edge through typical production and maintenance drilling tasks. It is sized to wire gauge number 22, which corresponds to 0.1570 inches in decimal. The 118-degree standard point angle is the most widely used geometry for drilling into a broad range of workpiece materials. With an overall length of 3.125 inches and a 2-inch flute length, it fits standard drill chucks without adapters. A straight-cylindrical shank ensures secure seating in keyless or keyed chucks. Licensed machinists, maintenance mechanics, sheet metal workers, and general tradespeople install and use this bit in everyday shop and field applications.

This drill bit suits residential and commercial maintenance, light fabrication, HVAC sheet metal work, electrical rough-in, and general mechanical applications where a wire gauge size 22 hole is required. The spiral flute geometry evacuates chips efficiently during through-hole and blind-hole drilling. The right-hand cut matches standard clockwise drill rotation. Regular spiral type and a tapered, web-thinned web configuration reduce thrust requirements and improve chip flow in softer and medium-hardness materials. Individual bits are packaged as single units, making it straightforward to replace worn tooling from an existing set.

Key Features

Compatibility

Designed as a general-purpose jobber length drill bit suitable for use in standard drill chucks accepting a 0.1570-inch straight-cylindrical shank, including benchtop drill presses, hand drills, and right-angle drill drivers used across HVAC, electrical, and mechanical trades.

Installation Notes

This bit is installed and used by machinists, sheet metal workers, and general tradespeople using standard drill equipment. Secure the shank fully in the chuck before operation and confirm the chuck is tightened properly to prevent slipping. Use appropriate cutting fluid or lubricant when drilling metals to extend bit life and improve hole quality. Wear eye protection and follow applicable shop safety standards when operating rotary cutting tools.
