Harvey Tool 32415-C4 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The HARVEY TOOL 32415-C4 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. With a 0.125 inch mill diameter, a 0.625 inch length of cut, and a 0.0150 inch corner radius, this tool balances edge strength with accurate profile control. The four-flute, right-hand spiral geometry supports both roughing and finishing passes in a single setup. An amorphous diamond PVD coating reduces friction and extends tool life in abrasive and hard materials. The stub-to-standard length profile keeps the tool rigid in tight-clearance operations where deflection must be minimized. Licensed machinists and CNC operators rely on this end mill for close-tolerance work across a range of workpiece materials.

This end mill is suited for milling steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials in both conventional and climb-milling strategies. The single-end, straight-cylindrical shank fits standard toolholders used on CNC machining centers and manual mills. At 0.125 inch diameter, it is built for miniature and detail work where larger tooling cannot reach. The 30-degree helix angle aids chip evacuation and smooth surface finishes. Centercutting geometry allows plunge entry where the application requires it.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• Amorphous diamond PVD coating reduces friction and extends tool life
• 0.0150 inch corner radius protects the cutting edge and reduces stress concentrations at part corners
• Four flutes with right-hand spiral geometry support both roughing and finishing passes
• Centercutting design allows direct plunge entry into the workpiece
• Straight-cylindrical shank fits standard CNC and manual mill toolholders

Compatibility

Designed for use with standard straight-bore toolholders on CNC machining centers and manual milling machines accepting a 0.125 inch shank diameter. Compatible with toolholding systems sized for miniature end mills in the HARVEY TOOL Miniature End Mills - Corner Radius - Stub and Standard series.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the toolholder and tighten to the toolholder manufacturer's specified clamping procedure. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and reduces dimensional accuracy on small-diameter carbide tools.
