Accupro 72016744 Corner Radius End Mill 3/8 in 6 Flute

Product Description

The ACCUPRO 72016744 is a 6-flute solid carbide corner radius end mill designed for aggressive material removal in high-temperature alloys and other difficult-to-machine workpiece materials. At 0.375 inches in diameter with a 0.015-inch corner radius, this single-end mill features a variable helix and variable index geometry that reduces harmonic vibration and chatter during deep cuts. The AlTiN+ coating provides thermal resistance and extended tool life in demanding milling applications. Overall length is 3.0 inches with a length of cut of 1.25 inches. It is centercutting and configured for right-hand cutting and right-hand flute direction.

This end mill is suited for precision slot milling, peripheral milling, and contour work in high-temp alloys including nickel-based superalloys and titanium-group materials, categorized under ISO material code S. It is a single-end tool intended for use in machining centers and CNC milling setups where tight tolerances and surface finish are critical. The 3/8-inch shank diameter is compatible with standard ER collet chucks, end mill holders, and hydraulic toolholders of the same bore size.

Key Features

• Variable helix and variable index geometry reduce chatter and improve surface finish in hard materials
• AlTiN+ coating delivers high thermal and oxidation resistance for dry or near-dry cutting of high-temp alloys
• Solid carbide construction provides rigidity and wear resistance compared to HSS equivalents
• Centercutting design allows plunge entry and ramping operations
• 0.015-inch corner radius protects the cutting edge and reduces corner chipping under load
• 6-flute configuration increases feed rate capability while maintaining chip clearance

Compatibility

Designed for use in CNC machining centers with standard 3/8-inch bore toolholding systems. Primary workpiece material designation is high-temp alloy (ISO code S), covering nickel, cobalt, and titanium-based alloys.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the tool shank is fully seated and secured in the toolholder to the manufacturer-specified engagement depth before running the spindle. Verify spindle orientation and programmed cutting direction match the right-hand configuration of this tool before initiating a cut. Inspect the cutting edges and coating condition before each use; do not run a chipped or worn carbide tool at full parameters.
