Harvey Tool 32440-C3 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The HARVEY TOOL 32440-C3 is a solid carbide corner radius end mill designed for precision milling of ferrous and non-ferrous materials. It features a 1/8 inch mill diameter, a 0.04 inch corner radius, and a 4-flute helical design with a 30-degree helix angle. The AlTiN PVD coating improves heat resistance and extends tool life in demanding cuts. With a 1/2 inch length of cut and 1-1/2 inch overall length, this single-end stub-standard tool is suited for tight-tolerance profiling, contouring, and finishing passes where edge integrity matters. It is installed and run by machinists and CNC tooling professionals working on vertical and horizontal machining centers.

This end mill is built for both roughing and finishing applications across a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and composites. Its miniature form factor makes it well suited for small-feature milling, slot work, and contour passes in die and mold work, precision component machining, and prototype fabrication. The straight cylindrical shank fits standard toolholders without modification. Right-hand flute direction and right-hand cutting direction are standard for conventional CNC setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating for elevated heat resistance and extended tool life
• 0.04 inch corner radius reduces stress concentration and improves corner durability
• 4-flute helical design supports both roughing and finishing material removal
• Center-cutting capable for plunge entry without a pilot hole
• Tight corner radius tolerance of plus or minus 0.001 inch for repeatable geometry

Compatibility

Designed for use with standard toolholders accommodating a 1/8 inch straight cylindrical shank. Compatible with CNC machining centers running steel, stainless steel, cast iron, non-ferrous metals, and composite workpiece materials.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer is in a safe state before handling. Seat the shank fully in the toolholder and torque the collet or set screw per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production run, as miniature diameter end mills are sensitive to even small amounts of runout.
