Harvey Tool 913008-C6 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The HARVEY TOOL 913008-C6 is a solid carbide corner radius end mill engineered for high-performance metal removal in difficult-to-machine materials. Built on Harvey Tool's Variable Helix End Mills for High Temp Alloys platform, this single-end, center-cutting tool features a 1/8 inch diameter, a 0.0100 inch corner radius, and four spiral flutes with a variable helix design that reduces harmonic vibration during aggressive cuts. The AlTiN (aluminum titanium nitride) PVD coating provides elevated heat resistance and extended tool life when working in high-temperature alloy environments. Overall length is 1.5 inches, with a 3/16 inch length of cut and a 1/8 inch straight-cylindrical shank. This tool is intended for use in precision CNC machining centers and high-precision toolholders.

This end mill is suited for both roughing and finishing operations in steel, stainless steel, cast iron, and hard alloys including high-temperature materials. The variable helix geometry helps suppress chatter in deep-pocket and slotting applications where tool deflection and vibration are primary concerns. The short flute length and 34-degree helix angle make it well-matched for tight-tolerance features in aerospace, medical, and die-mold workpieces. High-precision toolholders are recommended to maintain runout tolerances consistent with the close mill diameter tolerance of 0.0000 to -0.0020 inch.

Key Features

• Variable helix geometry reduces vibration and chatter in high-temp alloy cuts
• AlTiN PVD coating extends tool life in steel, stainless steel, cast iron, and hard alloys
• Center-cutting design allows plunge entry and ramping operations
• 0.0100 inch corner radius with a tight tolerance of plus or minus 0.0010 inch
• Right-hand cut and right-hand spiral flute direction; compatible with standard CNC spindle rotation
• Solid carbide construction for rigidity and dimensional stability at elevated cutting temperatures

Compatibility

Designed for use with high-precision toolholders. Recommended workpiece materials include steel, stainless steel, cast iron, and hard alloys as specified by the manufacturer for this series.

Installation Notes

Installation and tool changes must be performed with the CNC machine powered down and the spindle at a complete stop. Use a high-precision toolholder and verify runout before cutting to maintain tolerances appropriate to the close diameter and corner radius specs on this tool. Follow the machine tool manufacturer's guidelines for collet torque and tool projection. This tool is intended for use by qualified machinists and CNC setup technicians familiar with carbide end mill handling procedures.
