Harvey Tool 73993 Corner Radius End Mill 0.093 in 2 Flute

Product Description

The HARVEY TOOL 73993 is a miniature corner radius end mill designed for precision milling in tight-tolerance applications. Built from solid carbide with a bright/uncoated finish, it features a 0.0930-inch mill diameter, a 0.0300-inch corner radius, and a 2-flute, right-hand spiral configuration. The stub-length geometry keeps deflection low during light finishing and contour work. With a 30-degree helix angle and centercutting capability, the 73993 handles both plunge entry and peripheral cuts. It is a single-end tool intended for use in CNC machining centers and manual mills with compatible toolholders.

This end mill is suited for small-feature milling in steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composites. The miniature diameter and stub-standard series make it a practical choice for die and mold work, medical component machining, and precision part production where a standard-length tool cannot access confined geometries. A 1/8-inch straight cylindrical shank provides straightforward retention in collet-style and end mill toolholders.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 0.0300-inch corner radius reduces stress concentration and improves edge life on contoured surfaces
• Centercutting design allows direct plunge entry without pre-drilling
• 2-flute right-hand spiral geometry supports both roughing and finishing operations
• Bright/uncoated finish suitable for aluminum and non-ferrous applications where coating adhesion is a concern
• Miniature stub-standard series profile minimizes overhang and tool deflection at small diameters

Compatibility

Designed for use with standard collet and end mill toolholders accepting a 1/8-inch straight cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composites per manufacturer specification.

Installation Notes

A licensed machinist or CNC operator should install and qualify this tool using appropriate collet toolholders rated for the 1/8-inch shank diameter. Confirm spindle runout is within tolerance before cutting, as miniature-diameter carbide tools are sensitive to runout-induced breakage. Always set spindle speed and feed rate per material-specific guidelines before engaging the cut. Inspect the cutting edges under magnification before each use to confirm no chipping has occurred.
