Accupro 72087919 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The ACCUPRO 72087919 is a solid carbide corner radius end mill engineered for high-performance milling in demanding materials. With a 0.5000-inch mill diameter, six flutes, and a 2-inch length of cut, this tool removes material efficiently in high-temp alloys and other difficult workpiece materials. The AlTiN+ coating provides heat resistance and extended tool life at elevated cutting temperatures. Variable helix and variable index geometry reduce chatter and vibration, improving surface finish and tool stability. This is a single-end, right-hand cut, right-hand flute, centercutting end mill suited for profiling, slotting, and finishing operations in CNC machining environments.

This end mill is intended for use in CNC machining centers where high-temp alloys such as Inconel, titanium, and similar S-class materials are the primary workpiece. The 0.0100-inch corner radius protects the cutting edge and reduces chipping at the tool tip, making it appropriate for semi-finish and finish passes. With a 4-inch overall length and a 0.5000-inch shank diameter, it fits standard ER and end mill holders used in production and job shop environments. It is part of the ACCUPRO HS series, designed for rigorous material removal applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN+ coating for high heat resistance and extended tool life in high-temp alloys
• Variable helix and variable index design reduce vibration and improve surface finish
• Six-flute geometry increases feed rate capability and finish quality
• 0.0100-inch corner radius protects cutting edge and reduces chipping
• Centercutting design allows plunge entry into the workpiece

Compatibility

Designed for use with standard 1/2-inch end mill holders and ER collet chucks. Primary workpiece material designation is S-class (High-Temp Alloy), including nickel-based superalloys and titanium. Part of the ACCUPRO HS series.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle and tool holder are clean and free of debris before seating the shank. Torque the tool holder to the machine manufacturer's specification using calibrated tooling. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates wear on carbide tooling.
