Accupro 72090947 Corner Radius End Mill 0.625 in 6 Flute

Product Description

The ACCUPRO 72090947 is a 6-flute solid carbide corner radius end mill designed for high-performance milling in demanding materials. It carries an AlTiN+ coating and features a variable helix and variable index geometry, which reduces harmonic vibration and improves chip evacuation in difficult cuts. The 0.060-inch corner radius protects the cutting edge and extends tool life in high-temp alloy applications. At 0.625 inches in diameter with a 1.625-inch length of cut and a 3.5-inch overall length, this is a single-end, right-hand cutting tool suited for professional machinists working on aerospace, power generation, and oil-and-gas components.

This end mill is built specifically for cutting high-temp alloys, designated by workpiece material code S, which includes nickel-based superalloys, titanium, and cobalt-chrome materials. The centercutting design allows plunge entry, giving machinists flexibility in toolpath programming. The 5/8-inch shank diameter is compatible with standard ER collet chucks, shrink-fit holders, and hydraulic toolholders. It is well-suited for CNC machining centers operating in finishing and semi-finishing passes where edge integrity and thermal resistance are critical.

Key Features

• AlTiN+ coating provides high heat resistance and hardness for cutting high-temp alloys
• Variable helix and variable index geometry reduce chatter and improve surface finish
• 0.060-inch corner radius guards the cutting edge and extends tool life
• Centercutting design enables plunge milling and ramping operations
• 6-flute configuration increases feed rates and productivity in finish milling
• Solid carbide construction delivers rigidity and wear resistance in abrasive materials

Compatibility

Designed for use in CNC machining applications involving high-temp alloys (UNSPSC 27112803, Series HS). Compatible with standard 5/8-inch bore collet chucks, shrink-fit, and hydraulic toolholders.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the toolholder bore and collet are clean and free of chips before seating the shank. Verify spindle RPM and feed rate settings match the tool manufacturer recommendations for the specific workpiece material before engaging the cut. Do not exceed the rated length of cut when applying full-width passes.
