Harvey Tool 75230-C3 Corner Radius End Mill Solid Carbide

Product Description

The HARVEY TOOL 75230-C3 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous materials. It features a 0.1562-inch mill diameter with a 0.03-inch corner radius, four helical flutes, and an AlTiN (aluminum titanium nitride) PVD coating that extends tool life in abrasive cutting environments. The 9/16-inch length of cut and 2-inch overall length place this tool in the miniature stub and standard series, making it well suited for tight-tolerance profiling and finishing passes. Licensed machinists and CNC operators are the primary users of this tool in production and prototype machining environments.

This end mill is built for both roughing and finishing operations on steel, stainless steel, cast iron, non-ferrous metals, and composite materials. Its right-hand cutting direction, straight cylindrical shank, and center-cutting geometry make it compatible with standard toolholders used on vertical machining centers and CNC mills. The miniature diameter makes it a practical choice for detailed contour work, slot milling, and corner blending in close-tolerance parts where larger tools cannot reach.

Key Features

• 0.03-inch corner radius reduces stress concentrations at part corners and extends tool life
• AlTiN PVD coating provides high heat resistance for dry and semi-dry cutting in steel and stainless steel
• Four helical flutes support both roughing and finishing in a single tool
• Center-cutting geometry allows plunge entry without a pre-drilled hole
• Right-hand flute direction and right-hand cutting for standard CNC spindle setups
• Straight cylindrical shank fits standard collet and toolholder systems

Compatibility

Designed for use with standard toolholders compatible with a 3/16-inch shank diameter. Suitable for steel, stainless steel, cast iron, non-ferrous metals, and composite workpiece materials as specified by the manufacturer.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Secure the shank fully within the collet or toolholder to the minimum insertion depth before tightening to avoid runout. Verify spindle speed and feed rate parameters against the material being cut before starting the program. Do not exceed the rated length of cut when taking full-depth passes.
