Harvey Tool 61793-C4 Corner Radius End Mill 0.093in 3 Flute

Product Description

The HARVEY TOOL 61793-C4 is a solid carbide corner radius end mill engineered for precision milling in demanding materials including aluminum alloys, steel, stainless steel, cast iron, and composites. It features a 0.093-inch mill diameter, a 0.005-inch corner radius, and three flutes arranged in a variable helix configuration. The amorphous diamond (PVD) coating extends tool life and reduces built-up edge in non-ferrous and ferrous applications. The single-end, right-hand cutting geometry with spiral flutes supports both roughing and finishing passes. This tool is installed and operated by machinists and CNC tooling professionals on vertical and horizontal machining centers.

This end mill is suited for high-precision milling operations in aerospace, automotive, and general machining environments. The variable helix design reduces harmonic vibration during cuts, making it effective in long-reach and thin-wall scenarios. It accommodates steel, stainless steel, cast iron, aluminum, wood, and composite workpiece materials. A 0.25-inch length of cut and 1.5-inch overall length make this a short-series tool appropriate for tight-clearance pockets and slots. It is compatible with high-precision toolholders for runout-sensitive work.

Key Features

• 0.093-inch mill diameter with 0.005-inch corner radius for controlled edge blending
• Variable helix flute geometry reduces chatter and vibration during cuts
• Amorphous diamond PVD coating for extended wear life across ferrous and non-ferrous materials
• Three right-hand spiral flutes support both roughing and finishing in a single pass
• Center-cutting capable, allowing plunge entry into workpiece
• Short-series length (0.25-inch LOC) improves rigidity in precision pocket milling

Compatibility

Designed for use with high-precision toolholders on CNC machining centers. Suitable for milling aluminum, cast iron, steel, stainless steel, wood, and composite materials. Straight-cylindrical shank with h6 tolerance fits standard 1/8-inch collet and shrink-fit systems.

Installation Notes

This tool is installed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool changer or collet is properly seated before securing the shank. Use a high-precision toolholder to maintain runout tolerances consistent with the mill diameter tolerance of plus or minus 0.0005 inches. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool offsets and running initial cuts.
