Harvey Tool 882312-C6 Corner Radius End Mill 7 Flute Altin

Product Description

The HARVEY TOOL 882312-C6 is a solid carbide corner radius end mill engineered for high-performance milling in hardened steels ranging from 45 to 68 Rc. With a 3/16 inch mill diameter, 7 flutes, and a close pitch design, this tool delivers both roughing and finishing capability in demanding ferrous materials. The AlTiN PVD coating provides thermal resistance and extended tool life at elevated cutting speeds. A variable helix geometry helps reduce chatter and improve surface finish. This end mill is intended for use by machinists and tooling professionals working in precision CNC machining environments.

This end mill is designed for milling steel, stainless steel, cast iron, and hard alloys, making it well suited for die and mold work, aerospace components, and precision part production where hardened workpiece materials are common. It is a single-end tool with a straight cylindrical shank, intended for use with high precision toolholders in CNC machining centers. The regular length configuration and 9/16 inch length of cut suit it to standard depth-of-cut applications in hardened material.

Key Features

• Solid carbide construction for rigidity and wear resistance in hardened steels up to 68 Rc
• AlTiN PVD coating for high-temperature performance and extended tool life
• 7-flute close pitch design supports both roughing and finishing in a single tool
• Variable helix geometry reduces vibration and chatter during cutting
• 0.0150 inch corner radius with a tight tolerance of plus or minus 0.0010 inch
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility

Compatibility

Designed for use with high precision toolholders in CNC machining centers. Suitable for milling steel, stainless steel, cast iron, and hard alloys. Part of the HARVEY TOOL End Mills for Hardened Steels - Corner Radius series, rated for steels 45-68 Rc.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the toolholder is clean and the shank seats fully before securing; this tool is rated for high precision toolholders and runout should be verified prior to cutting. Confirm spindle direction is set to right-hand before initiating a cut. Follow the tool manufacturer's recommended speeds and feeds for the specific hardness and material being machined.
