Harvey Tool 792393-C3 Corner Radius End Mill 3/32 in 3 Flute

Product Description

The HARVEY TOOL 792393-C3 is a solid carbide corner radius end mill designed for high-performance milling in steel, stainless steel, and cast iron. It features a 3/32 inch (0.0930 inch) cutting diameter, a 0.0150 inch corner radius, and three flutes with a variable helix geometry that reduces harmonics and improves surface finish in medium alloy steels. The AlTiN PVD coating provides thermal resistance and extended tool life in abrasive ferrous materials. At 1-1/2 inches overall length with a short flute configuration, this end mill is well suited for rigidity-critical applications where reach and deflection are concerns.

This end mill is intended for both roughing and finishing operations in steel, stainless steel, and cast iron on CNC machining centers and milling machines. The centercutting design allows plunge entry, giving machinists flexibility in toolpath programming. The 1/8 inch straight-cylindrical shank fits standard collet chucks and toolholders. It is a single-end tool with right-hand cutting and right-hand flute direction, appropriate for conventional CNC milling setups in job shop and production environments.

Key Features

• Variable helix flute geometry reduces chatter in medium alloy steel and stainless steel cuts
• AlTiN PVD coating extends tool life in high-heat ferrous milling applications
• 0.0150 inch corner radius reduces stress concentration and chipping at the cutting edge
• Centercutting construction permits direct plunge entry without a pre-drilled hole
• Short flute length (9/64 inch LOC) maximizes rigidity and minimizes deflection in tight setups
• Right-hand spiral flutes provide efficient chip evacuation on CNC milling equipment

Compatibility

Designed for use with standard toolholders and collet chucks accepting a 1/8 inch straight-cylindrical shank. Suitable for milling steel, stainless steel, and cast iron workpieces. Part of the HARVEY TOOL Variable Helix End Mills for Medium Alloy Steels - Corner Radius series.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Secure the 1/8 inch shank in a collet or toolholder to the manufacturer-specified engagement depth before beginning any cut. Confirm spindle direction is set to right-hand rotation before operation. Do not exceed the tool's rated depth of cut or feed parameters for the workpiece material, as this end mill does not include through-coolant and relies on external coolant or air blast for chip clearance.
