Harvey Tool 892808 Corner Radius End Mill 1/8 in Solid Carbide

Product Description

The HARVEY TOOL 892808 is a solid carbide corner radius end mill designed for high-performance milling in aluminum alloys, steel, stainless steel, cast iron, and composite materials. The cutter measures 1/8 inch in diameter with a 3/8 inch length of cut and a 0.04 inch corner radius, delivering edge protection and improved surface finish in finishing and roughing passes alike. Three flutes with a variable helix geometry reduce harmonic vibration and chatter, making this tool well-suited for demanding aluminum machining applications. The single-end configuration and straight-cylindrical shank keep the setup straightforward for CNC machinists and tool-and-die professionals.

This end mill is part of the Variable Helix End Mills for Aluminum Alloys - Corner Radius series. It is intended for use in CNC machining centers and milling machines where precise corner geometry and tight tolerances are required. The right-hand flute direction and right-hand cutting action are standard for conventional CNC setups. With material removal capability spanning roughing and finishing in a single tool, it suits production environments and job-shop operations working with aluminum, ferrous metals, and non-ferrous stock. A high-precision toolholder is recommended for optimal runout performance.

Key Features

• Solid carbide construction for rigidity and wear resistance across multiple workpiece materials
• Variable helix design reduces chatter and improves chip evacuation in aluminum and non-ferrous cuts
• 0.04 inch corner radius with a tolerance of plus or minus 0.001 inch for consistent edge geometry
• Three flutes with helical flute type support both roughing and finishing in a single pass
• Center-cutting geometry allows plunge entry and full-slot milling capability
• Uncoated bright finish for use in applications where coating interaction with workpiece material is a concern

Compatibility

Designed for use with high-precision toolholders in CNC milling applications. Suitable for aluminum, cast iron, steel, stainless steel, wood, and composite workpiece materials per manufacturer specification. Part of the Variable Helix End Mills for Aluminum Alloys - Corner Radius series and the Material Specific End Mills series.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Secure the 1/8 inch straight-cylindrical shank in a high-precision collet or toolholder to minimize runout before cutting. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing or measuring tools. Verify corner radius and diameter tolerances with appropriate gauging if the application requires close geometric control.
