Accupro 72028129 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The ACCUPRO 72028129 is a solid carbide corner radius end mill designed for high-performance milling in demanding materials, particularly high-temperature alloys. With a 1/2-inch mill diameter and a 0.120-inch corner radius, it delivers a controlled edge break and improved tool life in difficult cuts. The AlTiN+ coating provides thermal resistance and wear protection at elevated cutting temperatures. Six flutes with a variable helix and variable index geometry reduce chatter and improve surface finish. This tool is a single-end, right-hand cut, center-cutting design suited for CNC milling operations in aerospace, energy, and precision manufacturing environments.

This end mill is intended for use on CNC machining centers and milling machines where high-temp alloys such as Inconel, titanium, and similar S-class workpiece materials are processed. The 5/8-inch length of cut and 2-1/2-inch overall length make it well suited for moderate-depth profiling, slotting, and contouring passes where corner integrity and edge life are critical. It is installed and operated by machinists and CNC programmers working in production and job-shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN+ coating provides high-temperature oxidation resistance and extended tool life
• Variable helix and variable index geometry reduce harmonic vibration and chatter
• 0.120-inch corner radius protects the cutting edge and improves part surface finish
• Center-cutting design allows plunge entry and versatile toolpath strategies
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility

Compatibility

Designed for milling high-temperature alloys (material code S), including nickel-based and titanium alloys, using standard 1/2-inch tool holders or collets on CNC milling and machining center spindles.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and the tool holder is clean and free of debris before seating the shank. Use a torque wrench and follow the tool holder manufacturer's specified clamping procedure. Verify runout with a dial indicator after installation before engaging the workpiece.
