Accupro 72088263 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The ACCUPRO 72088263 is a single-end, solid carbide corner radius end mill designed for high-performance milling in demanding materials. Built with a 1/2 inch diameter and six flutes, it delivers aggressive metal removal with a 2-inch length of cut and a 4-inch overall length. The AlTiN+ coating provides thermal resistance and extended tool life at elevated cutting temperatures. Variable index and variable helix geometry reduce harmonic chatter, making this tool well-suited for finishing and semi-finishing passes in high-temp alloys and other difficult-to-machine workpiece materials. Licensed machinists and CNC programmers select this end mill when tool stability and edge integrity are critical.

This end mill is engineered for primary use in high-temperature alloys, classified under workpiece material code S. It is a right-hand cut, right-hand flute tool with a centercutting configuration, allowing it to plunge as well as profile. The 1/2 inch shank diameter matches standard ER, side-lock, and hydraulic toolholders common in vertical and horizontal machining centers. It is appropriate for production environments where consistent corner geometry and tool life are required across multiple parts.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-temp alloys
• AlTiN+ coating for elevated heat resistance and extended tool life
• Variable helix and variable index geometry reduce vibration and chatter
• Six-flute design improves surface finish and feed rate potential
• Centercutting capability allows direct plunge entry
• 0.02 inch corner radius protects the cutting edge and improves corner strength

Compatibility

Designed as an OEM-style replacement and standard fitment for 1/2 inch straight-shank toolholders used in CNC machining centers requiring a single-end corner radius end mill in the HS series.

Installation Notes

This tool is installed by machinists or CNC setup technicians following standard toolholder torque and runout procedures per machine tool manufacturer guidelines. Ensure the spindle is fully stopped and locked out before changing tooling. Verify toolholder bore condition and cleanliness before seating the shank. Confirm programmed speeds and feeds are appropriate for the workpiece material and depth of cut before running the first part.
