Harvey Tool 46878-C6 Corner Radius End Mill 0.078in 3 Flute

Product Description

The HARVEY TOOL 46878-C6 is a solid carbide corner radius end mill engineered for demanding material removal in high-temperature alloys, stainless steel, steel, and cast iron. Measuring 0.078 inches in diameter with a 0.01-inch corner radius, this single-end tool features a variable helix geometry that reduces chatter and improves surface finish across both roughing and finishing operations. Three flutes provide an efficient chip evacuation pathway, and the AlTiN PVD coating delivers thermal resistance and extended tool life when cutting hard and abrasive workpiece materials. It is intended for use with high-precision toolholders to maximize runout control.

This end mill fits light-to-medium milling applications in CNC machining centers where tight tolerances and fine corner geometry are required. The 0.01-inch corner radius strengthens the cutting edge and reduces chipping in hard alloys. With a 15/64-inch length of cut, 1/8-inch straight cylindrical shank, and 1-1/2-inch overall length, it is well suited for finishing passes and profiling in deep pockets or constrained workspaces. Typical users include CNC machinists and tool-and-die professionals working in aerospace, medical, and precision manufacturing environments.

Key Features

• Variable helix design reduces harmonic vibration during high-speed cutting in hard alloys
• AlTiN PVD coating provides thermal and oxidation resistance for extended tool life
• 0.01-inch corner radius reinforces the cutting edge and minimizes chipping
• Center-cutting geometry enables plunge entry into workpiece material
• Right-hand cut and right-hand flute spiral for standard CNC milling setups
• Solid carbide construction maintains rigidity and dimensional stability at elevated cutting temperatures

Compatibility

Designed for use with high-precision toolholders. Suitable for milling steel, stainless steel, cast iron, and hard alloys. Part of the Harvey Tool Variable Helix End Mills for High Temp Alloys - Corner Radius series.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Seat the 1/8-inch straight cylindrical shank fully and concentrically in a high-precision collet or toolholder before tightening to minimize runout. Power down and lock out the spindle before any tool change. Do not exceed the toolholder manufacturer's recommended clamping torque or grip length specifications.
