Harvey Tool 980210-C3 Corner Radius End Mill 1/8 in

Product Description

The HARVEY TOOL 980210-C3 is a miniature corner radius end mill designed for precision milling in demanding materials. Built from solid carbide and coated with AlTiN via a PVD process, it handles steel, stainless steel, cast iron, non-ferrous metals, and composite materials. The 0.01 inch corner radius reduces stress concentrations at the cutting edge, extending tool life in both roughing and finishing operations. With 4 right-hand spiral flutes and a 30-degree helix angle, this single-end tool delivers efficient chip evacuation and smooth surface finishes at small diameters. It fits standard straight-cylindrical toolholders and is well suited for machinists working on tight-tolerance components.

This end mill is classified in the Miniature End Mills - Corner Radius - Stub and Standard series, making it appropriate for close-quarter milling operations where a short length of cut and compact overall length are required. The stub length configuration provides added rigidity, reducing deflection when cutting hardened steels, stainless alloys, cast iron, and non-ferrous materials. Typical applications include mold and die work, medical component machining, aerospace detail parts, and general precision shop work where a small-diameter, corner-radiused tool is called for. It is center-cutting and runs right-hand cutting direction.

Key Features

• Solid carbide construction with AlTiN PVD coating for heat and wear resistance in ferrous and non-ferrous materials
• 0.01 inch corner radius reduces edge chipping and stress concentration at the tool tip
• 4 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Center-cutting design allows plunge entry and versatile toolpath strategies
• Stub length configuration increases rigidity and minimizes deflection at 1/8 inch diameter
• Straight-cylindrical shank fits standard precision collets and toolholders

Compatibility

Compatible with standard straight-cylindrical toolholders accepting a 1/8 inch shank diameter. Suitable for use on CNC machining centers and manual mills equipped with appropriate collet systems. Rated for steel, stainless steel, cast iron, non-ferrous metals, and composite workpiece materials.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Seat the shank fully and evenly in the collet or toolholder to the recommended grip length before tightening. Avoid exceeding the tool diameter tolerance stack-up when setting runout, as small-diameter carbide tools are sensitive to imbalance and lateral load. Consult the machine tool builder documentation and applicable shop safety standards when programming feeds, speeds, and depth of cut for this tool diameter.
