Accupro 72025992 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The ACCUPRO 72025992 is a single-end, solid carbide corner radius end mill designed for high-performance milling in demanding materials. With a 1/2-inch mill diameter, six flutes, and an AlTiN+ coating, it delivers extended tool life and heat resistance in high-temperature alloy applications. The variable helix and variable index geometry reduce chatter and improve surface finish. A 0.09-inch corner radius protects the cutting edge and reduces stress concentration at the corner. This tool is installed and used by machinists and CNC operators working in aerospace, defense, and precision manufacturing environments.

This end mill is suited for roughing and finishing operations in high-temp alloys such as nickel-based superalloys, titanium, and similar S-class workpiece materials. The 1-1/4-inch length of cut and 3-inch overall length make it well-matched for moderate-depth pocketing, slotting, and contour work. It is center-cutting, allowing plunge entry. Right-hand flute direction and right-hand cutting direction are standard for conventional CNC vertical and horizontal machining center setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in difficult materials
• AlTiN+ coating provides high heat resistance and extended tool life in high-temp alloys
• Variable helix and variable index design reduces vibration and chatter during cutting
• 0.09-inch corner radius reduces edge chipping and stress at the cutting corner
• Center-cutting capable — allows direct plunge entry without a pre-drilled hole
• Six-flute configuration supports higher feed rates and improved finish quality

Compatibility

Designed for use in high-temperature alloy (S-class) workpiece materials including nickel-based superalloys and titanium. Fits standard 1/2-inch diameter toolholders including ER collets, shrink-fit holders, and hydraulic chucks compatible with a 1/2-inch shank.

Installation Notes

Installation is performed by machinists and CNC setup technicians. Ensure the machine spindle is fully stopped and the tool release is engaged before inserting or removing the end mill. Use a calibrated torque wrench when tightening collet nuts to the toolholder manufacturer specification. Confirm runout with a dial indicator after mounting — excessive runout will accelerate wear on a variable-helix tool of this type.
