Accupro 72055460 Corner Radius End Mill 1/4 Inch 6 Flute

Product Description

The ACCUPRO 72055460 is a single-end, solid carbide corner radius end mill designed for high-performance milling in demanding materials. Built for machinists and tool-and-die professionals, it carries a 1/4 inch (0.2500 inch) mill diameter with a 0.0100 inch corner radius and six flutes. The AlTiN+ coating improves heat resistance and tool life when cutting high-temperature alloys and similarly tough workpiece materials. Variable helix and variable index geometry reduce harmonic vibration during aggressive cuts, contributing to better surface finish and longer tool life in production environments.

This end mill is suited for high-speed machining of high-temperature alloys, including nickel-based and titanium alloys commonly found in aerospace and precision manufacturing applications. The centercutting design allows for plunge operations where the job calls for it. With a 1-1/4 inch length of cut and a 3 inch overall length, it fits standard toolholders accepting a 1/4 inch shank. Right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling setups in these material categories.

Key Features

• Solid carbide construction for rigidity and heat resistance in high-temp alloy cutting
• AlTiN+ coating for extended tool life and improved wear resistance
• Variable helix and variable index design reduces chatter and improves surface finish
• Six-flute configuration supports higher feed rates in hard materials
• Centercutting geometry allows plunge milling capability
• 0.0100 inch corner radius protects the cutting edge and reduces stress concentration at corners

Compatibility

Designed for use in standard 1/4 inch shank toolholders on CNC machining centers and manual mills. Primary workpiece material designation is high-temperature alloy (material code S), consistent with nickel-base, titanium, and similar hard alloy applications.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout specifications. Ensure the spindle and toolholder are clean and free of chips before seating the shank. Confirm proper tool projection and gauge length before beginning a cut. Follow all applicable shop safety procedures and machine lockout protocols when changing tooling.
