Chicago-latrobe 46124 Jobber Drill Bit Size 54 Hss

Product Description

The CHICAGO-LATROBE 46124 is a jobber length drill bit sized at wire gauge 54 (0.0550 inches decimal equivalent), manufactured from high speed steel with a bright uncoated finish. Designed for general-purpose drilling, this bit features a 118-degree standard point angle and a fast spiral flute configuration that promotes efficient chip evacuation in steel and similar workpiece materials. The straight-cylindrical shank measures 0.0550 inches in diameter and is compatible with standard drill chucks. At 1.875 inches overall length with a 0.875-inch flute length, this compact bit is well-suited for precision drilling in tight spaces. Technicians and machinists working on light fabrication, sheet metal, or mechanical assembly tasks will find this bit a reliable general-purpose option in the Series 150B line.

This bit is intended for use in hand drills, drill presses, and CNC equipment where a wire gauge 54 hole is required. It is commonly used in metalworking applications targeting steel as the primary workpiece material. The web-thinned, tapered web design reduces cutting resistance at the tip, making it effective for controlled entry in thin stock and precision work. It is sold individually and carries a minimum order quantity of 12 units, making it practical for shop stocking and service van inventory alike.

Installation Notes

Installation of this bit is performed by machinists, maintenance technicians, or trade professionals operating drill presses or portable drilling equipment. Secure the shank fully in the chuck and verify concentricity before drilling. Always use appropriate cutting fluid or lubrication when drilling steel to extend bit life and maintain hole tolerance. Wear appropriate eye protection and secure workpieces properly before operation.
