Chicago-latrobe 44311 Jobber Drill Bit Wire 41 Hss

Product Description

The CHICAGO-LATROBE 44311 is a jobber-length twist drill bit designed for general-purpose drilling in non-ferrous metals and similar materials. Built from high speed steel with a bright uncoated finish, it carries a wire gauge size of 41, equivalent to 0.0960 inches in decimal diameter. The 118-degree standard point angle and two-flute spiral configuration promote clean entry and efficient chip evacuation. The web-thinned, tapered web design reduces thrust during drilling and extends cutting tool life. At 2.375 inches overall length with a 1.375-inch flute length, it fits standard drill chucks and drill presses used throughout the trades.

This bit is suited for light-duty precision drilling tasks in fabrication, maintenance, HVAC, plumbing, and electrical work where a wire-gauge-size hole is required in non-ferrous metal stock, sheet metal, or similar workpieces. The straight-cylindrical shank seats reliably in both keyed and keyless chucks. It is sold individually per package and conforms to DIN 338 standards, making it a recognized specification in professional shop and field environments alike.

Key Features

• Wire size 41 (0.0960 inches) for precision-diameter holes in non-ferrous materials
• High speed steel construction rated for general-purpose cutting performance
• 118-degree standard point angle for clean, accurate starts without a center punch on most applications
• Web-thinned tapered web reduces drilling thrust and minimizes bit walking
• Bright uncoated finish allows easy visual inspection of cutting edge wear
• Conforms to DIN 338 standards for consistent dimensional accuracy

Compatibility

Designed as a general-purpose jobber-length drill bit in the CHICAGO-LATROBE Series 150D, suited for use in standard drill presses, hand drills, and drill drivers accepting a straight-cylindrical shank of 0.0960 inches in diameter.

Installation Notes

This bit is installed and serviced by machinists, fabricators, and trade technicians working with drill presses or portable drilling equipment. Secure the shank fully in the chuck and verify chuck key tightness before operation. Always wear appropriate eye protection and secure the workpiece before drilling. Reduce feed pressure when breakthrough is imminent to prevent bit grab or workpiece damage.
