Harvey Tool 874708-C6 Corner Radius End Mill 1/8 in 7 Fl

Product Description

The HARVEY TOOL 874708-C6 is a solid carbide corner radius end mill engineered for finishing operations in high-temperature alloys and other hard materials. It features a 1/8-inch mill diameter, 7 flutes with a variable helix design, and an AlTiN Nano PVD coating that sustains hardness and oxidation resistance at elevated cutting temperatures. The overall length is 2.5 inches with a 5/8-inch length of cut and a 0.005-inch corner radius. The right-hand cut, right-hand flute direction, and close pitch configuration make this tool suited for controlled finishing passes where surface finish and dimensional accuracy are critical.

This end mill is designed for finishing applications in steel, stainless steel, cast iron, and hard alloys. Its variable helix geometry reduces harmonic vibration during cutting, which is especially important when machining difficult materials that demand tight tolerances. The straight cylindrical shank with 1/8-inch diameter is compatible with high-precision toolholders. This tool is intended for use in CNC machining environments where a long-reach, small-diameter finisher is required in close-tolerance work.

Key Features

• AlTiN Nano PVD coating for oxidation resistance and extended tool life in high-temp alloys
• Variable helix design minimizes vibration during finishing passes
• 7-flute, close-pitch configuration supports smooth surface finish
• 0.005-inch corner radius with tolerance of plus or minus 0.001 inch
• Single-end, right-hand cut with right-hand helical flutes
• Non-centercutting design — intended strictly for finishing, not plunge cutting

Compatibility

Designed for use with high-precision toolholders in CNC milling applications involving steel, stainless steel, cast iron, and hard alloys. Primary workpiece material codes P, M, K, and H per ISO classification. Part of the HARVEY TOOL Variable Helix End Mills for High Temp Alloys - Finishers - Corner Radius series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a high-precision collet or toolholder to the toolholder manufacturer's specified clamping torque and runout tolerance. Confirm tool projection and reach before beginning a finishing pass. This tool is non-centercutting and must not be used for plunge entry.
