Chicago-latrobe 50361 Taper Length Drill Bit 0.0260 in Hss

Product Description

The CHICAGO-LATROBE 50361 is a taper length drill bit designed for precision drilling in metal fabrication, maintenance, and light industrial applications. Built from high-speed steel with a coated finish, it carries a wire size designation of #71 and a decimal diameter of 0.0260 inches. The 118-degree standard point angle suits general-purpose entry into alloy steel, carbon steel, and cast iron. At 2 inches overall length with a 0.75-inch spiral flute, this bit fits small-diameter drilling tasks where control and accuracy matter. Licensed machinists, toolroom technicians, and experienced tradespeople are the primary installers.

This drill bit is suited for small-diameter through-hole and spot-drilling operations in ferrous metals including alloy steel, carbon steel, and cast iron. The taper length body provides additional rigidity compared to jobber-length bits of the same diameter, making it a reliable choice in drill press and CNC setup work where runout and deflection must be minimized. The straight shank accepts standard drill chucks across bench-top and floor-standing machines.

Key Features

• Wire size #71 at 0.0260 inches diameter with a tight tolerance of +0.0000 to -0.0005 inches
• 118-degree standard point angle for general-purpose metal drilling
• High-speed steel construction with coated finish for wear resistance
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Web-thinned tapered web configuration reduces thrust and improves penetration
• Straight shank at 0.0260 inches diameter fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose taper length drill bit for use in alloy steel, carbon steel, and cast iron. Fits standard drill chucks accepting straight-shank tooling at 0.0260 inches shank diameter.

Installation Notes

Installation is performed by machinists or tradespeople using a drill press, CNC machine, or hand drill with an appropriate chuck. Secure the straight shank fully in the chuck before operation and verify zero runout on small-diameter bits to prevent breakage. At this diameter, reduced feed rates and proper cutting fluid application are standard practice when drilling ferrous metals. Follow applicable shop safety procedures and machine manufacturer guidelines throughout setup.
