Chicago-latrobe 50365 Taper Length Drill Bit 0.0210 in Hss

Product Description

The CHICAGO-LATROBE 50365 is a taper length drill bit designed for precision drilling in metalworking and general industrial applications. Built from high speed steel with a coated finish, this bit carries a 118-degree standard point angle that provides reliable centering and clean entry on a wide range of ferrous materials. The wire gauge size is No. 75, corresponding to a 0.0210-inch diameter. The spiral flute geometry with a web-thinned, tapered web configuration reduces thrust and improves chip evacuation. This bit is intended for use by machinists, tool and die technicians, and maintenance professionals requiring consistent performance at small drill diameters.

The 50365 is suited for drilling alloy steel, carbon steel, and cast iron in both production and maintenance-repair environments. The straight shank and compact taper length profile make it compatible with standard drill chucks on drill presses, CNC machining centers, and hand-held drilling equipment. The right-hand spiral flute and standard point geometry make this a general-purpose choice for operators working with small-diameter through-holes in ferrous stock.

Key Features

• Wire gauge size No. 75 at 0.0210 inches diameter for fine-tolerance drilling
• High speed steel construction with coated finish for extended service life
• 118-degree standard point angle for consistent self-centering on flat and curved surfaces
• Web-thinned, tapered web design reduces drilling thrust and improves chip flow
• Right-hand cut with regular spiral flute for standard machining setups
• Straight shank with 0.0210-inch shank diameter fits standard drill chucks without adapters

Compatibility

Rated for use in alloy steel, carbon steel, and cast iron. Designed as an OEM-style replacement or stock drill bit for applications requiring a No. 75 wire gauge straight-shank taper length drill in Series 120 configuration.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with small-diameter drill bit handling. Secure the straight shank firmly in a properly sized drill chuck before operation and verify runout before drilling to prevent bit deflection or breakage at this diameter. Power down and de-energize all equipment before changing bits. Refer to applicable shop safety standards and machine manufacturer guidelines for feed rate and speed recommendations appropriate to the workpiece material.
