Chicago-latrobe 44134 Wire Gauge 64 Jobber Drill Bit Hss

Product Description

The CHICAGO-LATROBE 44134 is a jobber length drill bit in wire gauge size 64, measuring 0.0360 inches in diameter, designed for general-purpose drilling in ferrous materials. Built from high speed steel with an oxide coating, this bit delivers reliable performance in cast iron and steel applications. It features a standard 118-degree split point, a spiral flute with regular helix, and a straight-cylindrical shank. Overall length is 1.5 inches with a flute length of 0.625 inches. The web-thinned, tapered web design reduces thrust and improves chip evacuation. This bit is installed by machinists, maintenance technicians, and metalworking professionals.

The 44134 is suited for production and maintenance drilling in cast iron and steel workpieces. Its compact 1.5-inch overall length makes it well-matched to small-hole work requiring precise, clean entry. The straight-cylindrical shank fits standard drill chucks without adapters. At 0.0360 inches, this bit is appropriate for tight-tolerance pilot holes, tap-drill prep, and instrument or light structural work where small wire gauge sizes are required. It conforms to DIN 338 standards, making it a recognized interchange in metric and imperial tooling environments.

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard drill chucks and drill presses suited to wire gauge size 64 tooling. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, CNC machine, or hand drill with a compatible chuck. Secure the straight-cylindrical shank firmly in the chuck and verify runout before drilling. Use appropriate cutting fluid or lubrication when drilling steel to extend bit life and maintain hole tolerance. At this small diameter, avoid side-loading or flexing the bit, as high speed steel is susceptible to breakage under lateral force.
