Harvey Tool 72805-C3 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The HARVEY TOOL 72805-C3 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 3/8 inch cutting diameter with a 0.0050 inch corner radius, four spiral flutes, and a right-hand cutting direction with right-hand flute orientation. The tool carries an AlTiN (aluminum titanium nitride) PVD coating, which improves heat resistance and extends tool life in high-temperature cutting environments. At 2.5 inches overall length with a 1 inch length of cut, this is a stub-standard geometry suited to rigidity-critical setups where deflection control matters.

This end mill is rated for roughing and finishing operations across a broad range of primary workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and composites. The centercutting design allows plunge entry, and the straight cylindrical shank fits standard toolholders. It belongs to the Harvey Tool Miniature End Mills - Corner Radius - Stub and Standard series, making it a practical choice for machinists running tight-tolerance features or small-diameter contour work in production or prototype environments.

Key Features

• 0.0050 inch corner radius breaks sharp edges and reduces stress concentration at part corners
• AlTiN PVD coating provides high-temperature wear resistance for ferrous and hard materials
• Four-flute spiral geometry supports both roughing and finishing in a single tool
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Solid carbide construction delivers rigidity and dimensional consistency in precision work

Compatibility

Designed for use with standard straight-bore toolholders. Part of the Harvey Tool Miniature End Mills - Corner Radius - Stub and Standard series. Rated for steel, stainless steel, cast iron, non-ferrous metals, and composite workpiece materials (ISO material codes P, M, K, N, O).

Installation Notes

Installation is performed by a machinist or toolroom technician using a compatible toolholder sized for a 3/8 inch straight cylindrical shank. Ensure the toolholder bore and collet are clean and free of chips before seating the tool. Confirm runout is within acceptable limits before cutting, as corner radius tools are sensitive to deflection at small radii. Always power down and lock out the spindle before changing tooling.
