Chicago-latrobe 44126 Jobber Drill Bit Wire 56 Hss

Product Description

The CHICAGO-LATROBE 44126 is a jobber-length drill bit in wire gauge size 56, with a decimal diameter of 0.0465 inches. It is manufactured from high speed steel with an oxide coating for wear resistance. The bit features a 118-degree standard point angle, a two-flute spiral configuration, and a straight-cylindrical shank. The overall length is 1.75 inches with a flute length of 0.375 inches. It is designed for general-purpose drilling in metalworking environments and is well-suited for machine shops, maintenance trades, and light fabrication work requiring precise small-diameter holes.

This bit is intended for use in cast iron and steel workpieces under general-purpose conditions. The web-thinned, tapered web design reduces entry resistance on harder materials. With a shank diameter matching the cutting diameter at 0.0465 inches, it seats directly in standard drill chucks without adapters. Typical applications include small fastener hole preparation, pilot drilling, and precision layout work where tight diameter tolerances matter. The Series 150 designation places this bit within a general-purpose line suited to production and field use alike.

Key Features

• Wire gauge size 56, 0.0465 inches decimal diameter with a tolerance of -0.0005 to 0.0000 inches
• High speed steel construction with oxide coating for corrosion and wear resistance
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust on entry
• Two-flute regular spiral design for efficient chip evacuation in steel and cast iron
• Straight-cylindrical shank seats directly in standard drill chucks without reduction sleeves
• Conforms to DIN 338 standard for jobber-length drill bits

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard drill chucks and drill presses accepting straight-cylindrical shanks at 0.0465 inches diameter. Rated for use in cast iron and steel workpiece materials.

Installation Notes

Install in a properly rated drill press, CNC machine, or hand drill with a chuck capacity covering 0.0465 inches. Ensure the workpiece is securely clamped before drilling. At this small diameter, low feed pressure and appropriate cutting speed are critical to prevent bit deflection or breakage. Coolant through is not supported on this bit; use a light cutting fluid applied externally when drilling harder steels to extend tool life.
