Harvey Tool 72810 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The HARVEY TOOL 72810 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous materials. It features a 3/8 inch diameter with a 0.010 inch corner radius, a 1 inch length of cut, and a 2.5 inch overall length. The 4-flute, right-hand spiral configuration supports both roughing and finishing operations in a single tool pass. The bright uncoated finish suits applications where coating compatibility with workpiece material is a concern. This is a centercutting, single-end tool with a straight cylindrical shank, making it compatible with standard toolholders used by machinists and tool-and-die professionals.

This end mill is suited for use in CNC machining centers and manual mills across job shops, aerospace, automotive, and general metalworking environments. It is designed to machine steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials. The stub and standard miniature series classification makes it appropriate for tight-tolerance work requiring a controlled corner radius. The 30 degree helix angle aids chip evacuation and surface finish quality across these varied material types.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• 0.010 inch corner radius with a tolerance of plus or minus 0.001 inch for consistent edge geometry
• 4 right-hand flutes with spiral geometry for combined roughing and finishing capability
• Centercutting design allows plunge entry into workpiece
• Bright uncoated finish compatible with a wide range of workpiece materials including aluminum and composites
• Normal pitch, non-variable helix, no chipbreaker for predictable cutting performance

Compatibility

Designed for use with standard toolholders accepting a 3/8 inch straight cylindrical shank. Part of the Harvey Tool Miniature End Mills Corner Radius Stub and Standard series.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the end mill. Seat the shank fully in the toolholder and torque the retention mechanism to the toolholder specification. Verify runout with a dial indicator before beginning a production cut, as excessive runout will accelerate wear and degrade corner radius accuracy.
