Accupro 72081359 Corner Radius End Mill 3/8 in 6 Flute

Product Description

The ACCUPRO 72081359 is a single-end, solid carbide corner radius end mill designed for high-performance milling in demanding materials. Built with a 0.375-inch diameter and six flutes, it carries an AlTiN+ coating that improves heat resistance and tool life when cutting high-temperature alloys. Variable index and variable helix geometry reduce harmonic chatter during aggressive cuts, making this tool well-suited for interrupted cuts and long-reach applications. The 0.060-inch corner radius protects the cutting edge and reduces stress concentration at part corners. Licensed machinists and CNC programmers specify this tool for precision work where edge integrity and surface finish matter.

This end mill is intended for use in CNC machining centers and manual mills where high-temp alloys such as titanium, Inconel, and similar S-group materials are the primary workpiece. The 2-inch length of cut and 4-inch overall length give the tool enough reach for deeper pocket and slot work without excessive overhang. Right-hand cutting and right-hand flute direction are standard for conventional CNC setups. The centercutting geometry allows plunge entries, adding flexibility to the operation sequence.

Key Features

• AlTiN+ coating for extended tool life in high-temperature alloy cutting
• Variable helix and variable index geometry reduce vibration and chatter
• Six-flute design increases feed rate potential and improves finish
• 0.060-inch corner radius protects edge and reduces stress at workpiece corners
• Centercutting capable — supports direct plunge entry
• Solid carbide construction provides rigidity and wear resistance

Compatibility

Designed for use in CNC machining centers with a 3/8-inch collet or end mill holder. Primary workpiece material designation is S (High-Temp Alloy), covering titanium, nickel-based superalloys, and similar materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the 3/8-inch shank in a properly sized collet or end mill holder and torque to the toolholder manufacturer specification. Ensure the machine spindle is fully stopped before tool changes. Verify runout with a dial indicator before commencing production cuts to protect both the tool and the workpiece.
