Chicago-latrobe 44315 Jobber Drill Bit Wire 45 Hss

Product Description

The CHICAGO-LATROBE 44315 is a jobber length drill bit designed for general-purpose drilling in non-ferrous metals and similar materials. It carries a wire gauge size of 45, equal to 0.0820 inches in diameter, and is manufactured from high speed steel with a bright, uncoated finish. The 118-degree standard point angle suits a wide range of common drilling applications. With an overall length of 2.125 inches and a flute length of 1.125 inches, this bit fits standard drill chucks and portable drills used by machinists, maintenance technicians, and metalworking tradespeople. The web-thinned, tapered web design reduces thrust required at the cutting tip.

This drill bit is suited for light-duty production and repair drilling in non-ferrous metal workpieces. The straight-cylindrical shank accepts standard three-jaw chucks on bench drills, drill presses, and handheld power drills. The regular spiral flute promotes chip evacuation during through-hole and blind-hole drilling. It is a single-piece, individually packaged bit sold to tradespeople and shops requiring precise small-diameter drilling consistent with DIN 338 standards.

Compatibility

Designed as a general-purpose jobber length drill bit in the Series 150D lineup, compatible with any standard three-jaw chuck accepting a 0.0820-inch straight-cylindrical shank on drill presses or handheld power drills.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with small-diameter tooling. Secure the straight-cylindrical shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Reduce feed pressure when breaking through the back side of a workpiece to avoid bit deflection or breakage at this small diameter. Follow applicable shop safety practices and tool manufacturer guidelines for speed and feed selection when drilling non-ferrous metals.
