Accupro 72082878 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The ACCUPRO 72082878 is a single-end, solid carbide corner radius end mill designed for high-performance milling in demanding materials. Built to a 1/2 inch diameter with six flutes and an AlTiN+ coating, it delivers aggressive material removal while maintaining edge integrity in high-temp alloys and similar difficult-to-machine workpiece materials. The 0.020 inch corner radius reduces stress concentration at the cutting edge, extending tool life in hard-metal applications. Variable helix and variable index geometry reduce harmonic vibration during the cut, improving surface finish and dimensional stability. This tool is sized for use in standard 1/2 inch collets or end mill holders on vertical machining centers and manual mills.

The 72082878 is intended for milling high-temperature alloys, classified under workpiece material code S, which includes nickel-base and cobalt-base superalloys common in aerospace, power generation, and medical manufacturing. With a 1-1/4 inch length of cut and 3 inch overall length, it suits moderate-depth slotting, profiling, and finishing passes where rigidity and coating performance are critical. Single-end configuration means the tool is replaced rather than flipped when worn.

Key Features

• AlTiN+ coating provides oxidation resistance and hardness retention at elevated cutting temperatures
• Variable helix and variable index design reduces chatter and vibration during aggressive cuts
• Solid carbide construction for rigidity and wear resistance in hard workpiece materials
• 0.020 inch corner radius protects the cutting edge and reduces stress risers at part corners
• Center-cutting capable, allowing plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand flute direction — compatible with standard spindle rotation

Compatibility

Designed for use with 1/2 inch collet chucks or end mill holders; primary workpiece material designation is High-Temp Alloy (code S). No specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before loading or unloading the tool. Secure the shank to the full recommended gauge-line depth in the holder and verify runout with a dial indicator before beginning a cut. Follow the tool manufacturer and machine OEM guidelines for feeds, speeds, and coolant strategy when machining high-temperature alloys.
