Harvey Tool 72860-C3 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The HARVEY TOOL 72860-C3 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, a 0.06 inch corner radius, and a 1 inch length of cut, making it well-suited for both roughing and finishing operations. The AlTiN PVD coating extends tool life in demanding materials including steel and stainless steel. With 4 right-hand helical flutes at a 30-degree helix angle and a straight cylindrical shank, this single-end tool delivers consistent chip evacuation and surface finish in tight-tolerance machining environments.

This end mill is part of the Harvey Tool Miniature End Mills - Corner Radius - Stub and Standard series. It is used in CNC machining centers and milling setups where corner radius geometry is required to reduce stress concentrations and improve part surface quality. Typical applications include profiling, slotting, and contouring in steel, stainless steel, cast iron, non-ferrous metals, and composite materials. It fits standard toolholders accepting a 3/8 inch straight-cylindrical shank.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN PVD coating for enhanced heat resistance and extended tool life in ferrous materials
• 0.06 inch corner radius reduces stress concentrations and improves edge durability
• 4 right-hand helical flutes with 30-degree helix angle for efficient chip evacuation
• Center-cutting design allows plunge entry without a pre-drilled hole
• Single-end, straight-cylindrical shank compatible with standard toolholders

Compatibility

Designed for use with standard toolholders accepting a 3/8 inch straight-cylindrical shank. Suitable for CNC milling applications in steel, stainless steel, cast iron, non-ferrous metals, and composite workpiece materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the specified clamping torque for the toolholder in use and verify runout with a dial indicator before cutting. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
