Harvey Tool 997962-C3 Corner Radius End Mill 0.062 in 4 Flute

Product Description

The HARVEY TOOL 997962-C3 is a solid carbide corner radius end mill designed for precision material removal in demanding machining applications. Built to miniature stub and standard dimensions, it features a 0.0620-inch mill diameter, a 0.0150-inch corner radius, and four right-hand spiral flutes with a 30-degree helix angle. The AlTiN (aluminum titanium nitride) PVD coating extends tool life when cutting ferrous and hard materials. At 1.5 inches overall length with a 1/8-inch straight cylindrical shank, this end mill is suited for both roughing and finishing passes. Licensed machinists and toolroom technicians are the primary users.

This end mill is intended for use in CNC machining centers and manual mills requiring tight-tolerance work in a miniature footprint. It is well suited for applications involving steel, stainless steel, cast iron, non-ferrous metals, and composites. The 3/32-inch length of cut and centercutting geometry allow plunge entries and slot milling in confined features. It mounts in standard toolholders accepting a 1/8-inch shank. Typical applications include mold and die work, medical components, aerospace detail parts, and precision prototype machining where a small corner radius is required to blend walls and floors.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials
• AlTiN PVD coating improves heat resistance and tool life in steel and stainless steel cuts
• 0.0150-inch corner radius reduces stress concentrations at part corners and extends cutter life
• Centercutting design enables direct plunge entry without a pre-drilled pilot hole
• 4-flute, right-hand spiral geometry supports both roughing and finishing in a single tool
• Miniature stub form factor fits tight clearance pockets and small-feature work

Compatibility

Designed for use with standard toolholders accepting a 1/8-inch straight cylindrical shank. Suitable for machining steel, stainless steel, cast iron, non-ferrous metals, and composite materials.

Installation Notes

Installation is performed by qualified machinists following shop toolholding procedures. Ensure the toolholder bore and collet are clean and undamaged before seating the shank to the correct insertion depth. Confirm spindle runout is within acceptable limits before cutting, as runout has an outsized effect on tool life and part finish at miniature diameters. Do not exceed the manufacturer's recommended speeds and feeds for the workpiece material and coating type.
