Harvey Tool 50108-C8 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The HARVEY TOOL 50108-C8 is a solid carbide corner radius end mill designed for high-performance milling in aluminum alloys, steel, stainless steel, cast iron, and composite materials. It features a 1/8 inch mill diameter, a 0.005 inch corner radius, and three flutes with a variable helix geometry that reduces chatter and improves surface finish during both roughing and finishing passes. The TiB2 (titanium diboride) PVD coating is optimized for non-ferrous metals, particularly aluminum, reducing built-up edge and extending tool life. Overall length is 1.5 inches with a 3/8 inch length of cut. This tool is a single-end, right-hand cut, right-hand flute configuration intended for use in high-precision toolholders on CNC machining centers.

This end mill is part of the Harvey Tool Variable Helix End Mills for Aluminum Alloys - Corner Radius series. It is suited for precision profiling, contouring, and slotting operations in a shop or production environment. The 0.005 inch corner radius reduces stress concentrations at part edges and extends tool life compared to sharp-corner end mills. It is appropriate for aerospace, automotive, and general metalworking applications where tight tolerances and fine surface finishes are required in aluminum and other listed workpiece materials. Compatible with standard straight-cylindrical shank toolholders with a 1/8 inch bore.

Key Features

• Variable helix geometry reduces harmonics and chatter during aggressive cuts
• TiB2 PVD coating optimized for aluminum and non-ferrous metal machining
• 0.005 inch corner radius with a tolerance of plus or minus 0.001 inch for edge protection and finish quality
• Center-cutting design allows plunge entry
• Solid carbide construction provides rigidity and heat resistance
• Right-hand cut and flute direction for standard CNC spindle compatibility

Compatibility

Designed for use with high-precision toolholders accepting a 1/8 inch straight-cylindrical shank. Suitable for milling aluminum, cast iron, steel, stainless steel, wood, and composite workpiece materials. Part of the Harvey Tool Variable Helix End Mills for Aluminum Alloys - Corner Radius and Material Specific End Mills series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Seat the shank fully in the toolholder and torque the set screw or collet nut per the toolholder manufacturer specification. Verify runout with a dial indicator before first cut, as this tool is designed for high-precision toolholders where runout directly affects surface finish and tool life. Do not exceed the manufacturer-recommended cutting parameters for the workpiece material.
