Accupro 72050164 Corner Radius End Mill 1/4 in 6 Flute

Product Description

The ACCUPRO 72050164 is a single-end, solid carbide corner radius end mill designed for high-performance milling in demanding materials. With a 0.25-inch mill diameter, six flutes, and an AlTiN+ coating, it is built to handle high-temperature alloys and other difficult-to-machine workpiece materials. The 0.060-inch corner radius adds edge strength and reduces chipping on profiling passes. Variable helix and variable index geometry help reduce harmonic vibration and chatter during cuts. Machinists and CNC operators working in aerospace, medical, and energy sectors will find this tool well-suited for precision work on heat-resistant alloys.

This end mill is intended for milling high-temperature alloys, classified under material code S, which includes nickel-base, titanium, and cobalt-base alloys. It is a right-hand cutting, right-hand flute tool with centercutting capability, allowing it to be used for slotting, profiling, and plunge entry operations. The 3/8-inch length of cut and 2-inch overall length make it appropriate for shallow-to-moderate depth milling applications in precision shop environments.

Key Features

• Solid carbide construction for rigidity and heat resistance in high-temp alloy cutting
• AlTiN+ coating improves thermal protection and tool life in abrasive materials
• Variable helix and variable index design reduce chatter and improve surface finish
• 0.060-inch corner radius protects the cutting edge and extends tool life on profiling passes
• Centercutting geometry enables plunge milling without a pre-drilled entry hole
• Six-flute configuration supports higher feed rates and improved finish quality

Compatibility

Designed for use in CNC machining centers and manual milling machines with a 1/4-inch collet or end mill holder. Primary application is high-temperature alloy workpieces as specified by the manufacturer.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and locked out. Ensure the shank is properly seated and torqued in the collet or tool holder per the holder manufacturer's specifications before starting the spindle. Verify runout with a dial indicator after tool setup to protect edge integrity. Follow shop-specific feeds and speeds for high-temp alloy applications, as improper parameters accelerate edge wear.
