Harvey Tool 959660-C3 Corner Radius End Mill 0.06 in 4 Flute

Product Description

The HARVEY TOOL 959660-C3 is a solid carbide corner radius end mill designed for precision finishing operations in demanding machining environments. With a 0.0600-inch mill diameter, a 0.0050-inch corner radius, and four right-hand spiral flutes, this tool removes material cleanly while protecting part edges from chipping or cracking. The AlTiN PVD coating increases surface hardness and thermal resistance, extending tool life in abrasive and high-temperature cutting conditions. At 2.5 inches overall length with a long 0.3120-inch length of cut, this miniature end mill reaches into tight pockets and slots that standard-length tools cannot access. It is installed by machinists and toolroom professionals on CNC machining centers and manual mills.

This end mill is suited for finishing passes on steel, stainless steel, cast iron, non-ferrous metals, and composite materials. The long-flute geometry makes it particularly useful in die and mold work, medical component machining, and aerospace part production where small-diameter, deep-reach cutting is required. The centercutting design allows plunge entry, giving operators flexibility in toolpath programming. The 0.1250-inch straight cylindrical shank fits standard collet toolholders used on most CNC machining centers.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials
• AlTiN PVD coating improves heat resistance and extends tool life in steel and stainless steel applications
• 0.0050-inch corner radius protects cutting edges and reduces stress concentrations at part corners
• Long-flute geometry with 0.3120-inch length of cut reaches deep pockets and slots
• Centercutting design permits direct plunge entry into the workpiece
• 30-degree helix angle promotes smooth chip evacuation during finishing passes

Compatibility

Designed for use with standard collet-style toolholders accepting a 0.1250-inch straight cylindrical shank. Compatible with CNC machining centers and manual mills configured for right-hand cutting direction. Suitable for workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and composites.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer specifications for runout and setscrew torque. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the toolholder. Verify collet size matches the 0.1250-inch shank diameter before clamping. Inspect the cutting edges and coating for damage before each use, as miniature-diameter carbide tools are sensitive to impact and improper handling.
