Accupro 72025679 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The ACCUPRO 72025679 is a solid carbide corner radius end mill designed for high-performance milling in demanding materials. It features a 1/2 inch diameter, six flutes, and an AlTiN+ coating that provides heat resistance and extended tool life in high-temperature alloy applications. The 0.090 inch corner radius reduces stress concentration at the cutting edge, and the variable helix and variable index geometry help suppress chatter and improve surface finish. This is a single-end, center-cutting tool with right-hand flute direction and right-hand cutting direction, suited for machinists and tool-and-die professionals working in production or job-shop environments.

This end mill is intended for use in high-temp alloy workpiece materials, classified under primary workpiece material code S. Typical applications include roughing and finishing passes on nickel-based superalloys, titanium, and similar hard-to-machine materials where tool wear resistance and edge stability are critical. The 5/8 inch length of cut and 2-1/2 inch overall length make it appropriate for moderate-depth pockets, slots, and profiling operations on vertical or horizontal machining centers.

Key Features

• AlTiN+ coating for high heat resistance in high-temp alloy cutting
• Variable helix and variable index design reduces chatter and improves surface finish
• 0.090 inch corner radius extends edge life and reduces workpiece stress
• Six-flute geometry increases feed rate capability and finish quality
• Center-cutting capability allows plunge entry
• Solid carbide construction provides rigidity and wear resistance

Compatibility

Designed for use in CNC machining centers accepting a 1/2 inch straight shank; primary workpiece material is high-temp alloy (material code S), including nickel-based and titanium alloys.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling setup. Secure the shank in a collet or end mill holder to the full recommended grip length before operating. Verify spindle speed, feed rate, and depth of cut against the tool manufacturer's cutting data for the specific workpiece material before running. Never exceed the tool's rated cutting parameters, as solid carbide is rigid but brittle under excessive lateral load.
