Chicago-latrobe 44236 Jobber Drill Bit 9/16 Inch Hss

Product Description

The CHICAGO-LATROBE 44236 is a jobber length drill bit designed for general-purpose drilling in non-ferrous metals and similar materials. Manufactured from high speed steel with a bright uncoated finish, it features a 118-degree standard point angle and a regular spiral flute for efficient chip evacuation. The straight-cylindrical shank measures 9/16 inch in diameter, matching the cutting diameter for straightforward chuck mounting. Overall length is 6-5/8 inches with a flute length of 4-13/16 inches. The web-thinned, tapered web design reduces thrust during entry and helps maintain point integrity across repeated use. This bit is part of the Series 150D line and conforms to DIN 338 standards.

The 44236 is suited for production and maintenance drilling operations where a reliable, standard jobber geometry is needed. Its 9/16 inch diameter and 6-5/8 inch overall length make it a common choice for structural, fabrication, and mechanical service work involving non-ferrous metals. The right-hand cut and two-flute spiral configuration work with standard drill presses, hand drills, and magnetic base drills. It is appropriate for use by machinists, pipefitters, ironworkers, sheet metal workers, and general maintenance tradespeople who need a dependable general-purpose bit without specialty coatings.

Installation Notes

A licensed machinist or qualified tradesperson should secure the shank fully in the chuck and verify runout before drilling. Ensure the workpiece is clamped or fixtured before starting the cut to prevent grab or walking. Use appropriate cutting fluid or lubrication when drilling non-ferrous metals to extend bit life and maintain dimensional tolerance. Inspect the cutting edges and web before each use and replace the bit if chipping or excessive wear is present.
