Chicago-latrobe 46073 Jobber Drill Bit Wire 3 Hss 118 Deg

Product Description

The CHICAGO-LATROBE 46073 is a jobber length drill bit in wire size 3 (0.2130 inches decimal), ground from high speed steel with a bright uncoated finish. It carries a standard 118-degree drill point angle with a fast spiral, two-flute configuration and a web-thinned, tapered web for improved chip evacuation and reduced thrust in general-purpose drilling. The straight-cylindrical shank seats directly in standard drill chucks. Overall length is 3.75 inches with a 2.5-inch flute length. This is a right-hand cut bit suited for production and maintenance drilling in steel and similar materials.

The 46073 is designed for general-purpose metal drilling in steel workpieces across production, maintenance, and fabrication environments. Its Series 150B designation places it in a widely stocked jobber family used by machinists, pipefitters, ironworkers, and maintenance mechanics. The wire size 3 diameter is commonly called for in tapping, clearance, and pilot hole applications. No coolant-through capability is present, so it is intended for conventional drilling with external or flood lubrication as needed.

Designed as a general-purpose jobber length drill bit for use in standard drill chucks accepting a 0.2130-inch straight-cylindrical shank. Primary workpiece material is steel; suitable for general-purpose applications within the 0.2000 to 0.2500-inch drill bit size range.

Installation Notes

Install in a drill press, hand drill, or CNC spindle with a chuck rated for the shank diameter. Secure the shank fully in the chuck before operation and verify chuck key is removed before starting the machine. Apply appropriate cutting fluid or lubricant when drilling steel to extend tool life and improve hole quality. Follow applicable shop safety practices and machine guarding requirements during use.
