Accupro 72016983 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The ACCUPRO 72016983 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. With a 0.5000 inch mill diameter and six flutes, it delivers a high feed-per-tooth rate and excellent surface finish in difficult materials. The AlTiN+ coating provides thermal resistance and extended tool life at elevated cutting temperatures. A 0.0150 inch corner radius protects the cutting edge and reduces chipping at corners. Variable helix and variable index geometry reduce harmonic vibration and chatter during aggressive cuts. This tool is single-end and centercutting, making it suitable for both plunge and peripheral milling operations.

This end mill is rated for use in high-temperature alloys (material code S), including nickel-based superalloys, titanium, and cobalt-chrome alloys commonly encountered in aerospace, medical device, and industrial turbine component machining. Right-hand cutting direction with a right-hand flute spiral suits standard CNC vertical and horizontal machining centers. The 1/2 inch shank fits standard ER and side-lock toolholders used across production and job-shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN+ coating for high-temperature oxidation resistance and extended tool life
• Variable helix and variable index design reduces chatter and vibration
• 0.0150 inch corner radius protects cutting edges and reduces edge chipping
• Centercutting geometry allows direct plunge entry
• Six-flute configuration maximizes metal removal rate in finishing and semi-finishing passes

Compatibility

Designed for use in CNC machining centers with standard 1/2 inch toolholding systems. Primary workpiece material designation is high-temp alloy (material code S), including nickel superalloys, titanium alloys, and similar difficult-to-machine materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading tooling. Confirm runout at the toolholder before cutting, as excessive runout accelerates edge wear on multi-flute carbide tools. Follow machine tool manufacturer torque specifications for the toolholder style in use.
