Harvey Tool 908908-C6 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The HARVEY TOOL 908908-C6 is a solid carbide corner radius end mill designed for high-temperature alloy machining applications. It features a 1/8 inch diameter, a 0.005 inch corner radius, and four flutes with a variable helix geometry that reduces harmonics and chatter during aggressive cuts. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting hard, abrasive materials. At 1-1/2 inches overall length with a 3/16 inch length of cut, this is a short-series tool suited for rigid setups. Qualified machinists and tooling specialists install and apply this end mill in CNC milling operations.

This end mill is engineered for use on steel, stainless steel, cast iron, and hard alloys including high-temperature materials. The variable helix design makes it particularly effective in roughing and finishing passes where vibration control is critical. The center-cutting geometry allows plunge entry, and the right-hand flute direction with right-hand cutting orientation suits standard CNC milling spindles. It is intended for use with high-precision toolholders to maintain concentricity and minimize runout at the small diameter. Single-end configuration is standard.

Key Features

• Variable helix geometry reduces chatter and improves surface finish on hard and high-temp alloys
• AlTiN PVD coating delivers thermal and wear resistance in steel, stainless, cast iron, and hard alloy cuts
• Center-cutting design allows direct plunge and ramp entry
• 0.005 inch corner radius protects cutting edge and reduces stress concentration at the tool tip
• Solid carbide construction provides rigidity and precision in short-series length
• Compatible with both roughing and finishing material removal strategies

Compatibility

Designed for use with high-precision toolholders in CNC milling applications involving 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 should be performed by a qualified machinist or tooling technician. Secure the shank in a high-precision toolholder to the specified h6 shank diameter tolerance to minimize runout. Ensure the machine spindle is fully stopped and the CNC program is cleared before tool changes. Do not exceed the rated length of cut when programming axial depth of pass.
