Accupro 72080492 Corner Radius End Mill 3/8 in 6 Flute

Product Description

The ACCUPRO 72080492 is a 6-flute solid carbide corner radius end mill designed for high-performance milling in high-temperature alloys and other demanding workpiece materials. With a 3/8-inch (0.3750 inch) mill diameter and an AlTiN+ coating, this tool delivers thermal resistance and wear life in elevated-heat cutting environments. The 0.0100-inch corner radius protects the cutting edge under heavy loads, while variable index and variable helix geometry reduce harmonics and chatter during aggressive passes. Licensed machinists and CNC programmers specify this tool for tight-tolerance finish work where edge integrity matters.

This end mill is suited for single-end use in vertical machining centers, CNC mills, and similar multi-axis equipment. Its primary application is machining high-temp alloys (UNSPSC material code S), including nickel-based superalloys, titanium, and similar aerospace and energy-sector materials. The 2-inch length of cut and 4-inch overall length provide adequate reach for most cavity and contour operations without excessive tool overhang.

Key Features

• AlTiN+ coating for high-heat resistance in hard and high-temp alloy cutting
• Variable helix and variable index geometry to suppress vibration and chatter
• 0.0100-inch corner radius (0.25 mm) extends edge life and reduces chipping at the corner
• Solid carbide construction for rigidity and dimensional stability
• Center-cutting design allows plunge entry and ramp milling
• Right-hand flute direction and right-hand cutting for standard spindle use

Compatibility

Designed for use in standard 3/8-inch ER or end mill collet holders. Primary workpiece material designation is high-temp alloy (code S). No specific machine model compatibility is stated by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Verify spindle is fully powered down and locked out before changing tooling. Seat the shank fully and evenly in the collet or tool holder to the recommended gauge depth before tightening. Confirm runout at the collet face before initiating a cut, as excessive runout accelerates wear on variable-helix geometry tools.
