Accupro 72072036 Corner Radius End Mill 3/8 in 6 Flute

Product Description

The ACCUPRO 72072036 is a solid carbide corner radius end mill designed for high-performance milling in demanding materials, including high-temperature alloys. The tool measures 0.375 inches in diameter with a 0.5-inch length of cut and a 2-inch overall length. It features a variable helix and variable index geometry, a 6-flute configuration, and an AlTiN+ coating for extended tool life under elevated cutting temperatures. Single-end construction with a right-hand cutting direction and centercutting capability make it a versatile choice for both slotting and profiling operations in CNC machining environments.

This end mill is engineered for use in aerospace, power generation, and industrial machining applications where high-temp alloys such as Inconel, titanium, and cobalt-chrome are common workpiece materials. The 0.010-inch corner radius reduces edge chipping and stress concentration at the cutting tip, making it well suited for finish milling passes on complex part geometries. Machinists and CNC operators working with tight tolerances on exotic materials will find the variable helix design helps manage harmonics and reduce chatter during extended cuts.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-temp alloy cutting
• AlTiN+ coating provides heat resistance and reduced friction at elevated cutting speeds
• Variable helix and variable index geometry reduce chatter and improve surface finish
• 6-flute design increases feed rate potential and improves chip load per tooth
• 0.010-inch corner radius (0.25 mm) protects the cutting edge and reduces stress risers
• Centercutting capability allows plunge milling and ramp entry

Compatibility

Designed for use in CNC machining centers with standard 3/8-inch collets or tool holders. Primary workpiece material designation is high-temp alloy (material code S), consistent with nickel-based superalloys, titanium alloys, and similar materials.

Installation Notes

This tool should be installed by qualified CNC machinists or tooling technicians using a properly balanced tool holder and collet matched to the 0.375-inch shank diameter. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify runout with a dial indicator before cutting to maximize tool life and surface finish quality. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut when working with high-temp alloys.
