Hertel 84578343 Jobber Drill Bit Wire 79 Hss 118

Product Description

The HERTEL 84578343 is a jobber-length drill bit sized to wire gauge 79, equivalent to 0.0145 inches in decimal diameter. Built from high speed steel with a bright uncoated finish, it is engineered for general-purpose drilling in metal, plastic, and similar materials. The standard 118-degree split point geometry with web thinning reduces walking and lowers the thrust required to start the cut. At 0.75 inches overall length, this is a compact bit suited for precision work in tight clearances. The straight-cylindrical shank seats securely in standard drill chucks. The 2-flute spiral configuration with a regular spiral type and tapered web provides efficient chip evacuation in short-depth holes.

This bit is appropriate for production and maintenance drilling tasks where a wire-gauge size in the sub-0.02-inch range is required. Typical applications include tapping prep work, instrument panel drilling, electronics assembly, and HVAC component fabrication where small fastener clearance holes are needed. The general-purpose grade makes it a cost-effective option for shops and field technicians who need consistent small-diameter performance without specialty tooling.

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 0.0145-inch straight-cylindrical shank.

Installation Notes

Install and remove this bit with the drill or press powered down and the chuck key fully disengaged before operation. Use appropriate eye protection and secure the workpiece before drilling. High speed steel bits are susceptible to heat damage at excessive feed rates — use cutting fluid or reduce feed when drilling hard metals. Consult applicable shop safety standards and tool manufacturer guidelines for speed and feed recommendations by material type.
