Sandvik Coromant 8037552 Corner Radius End Mill 1/4in

Product Description

The SANDVIK COROMANT 8037552 is a solid carbide corner radius end mill designed for high-performance milling of non-ferrous and light-alloy materials. Part of the CoroMill Dura series, it features a 0.25-inch cutting diameter, a 0.06-inch corner radius, and a ZrN (zirconium nitride) coating that reduces built-up edge and extends tool life in aluminum and similar materials. The three-flute, right-hand spiral geometry with variable helix and variable index reduces chatter and improves surface finish in demanding machining environments. Licensed machinists and CNC operators in job shops and production facilities are the primary users of this tool.

This end mill suits single-end, center-cutting operations where a corner radius is required to reduce stress concentrations at the base of a feature. With a 1-inch length of cut and 3-inch overall length on a straight cylindrical 0.25-inch shank, it fits standard collet chucks and end mill holders in vertical and horizontal machining centers. The CoroMill Dura series targets material grade N1BZ, making this tool well suited for aluminum, copper, brass, and other non-ferrous alloys in both roughing and finishing passes.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous milling
• ZrN coating reduces friction and built-up edge when cutting aluminum and similar alloys
• Variable helix and variable index geometry minimizes vibration and chatter
• 0.06-inch corner radius reduces stress risers and improves feature edge quality
• Center-cutting design allows plunge entry without a pre-drilled pilot hole
• Right-hand cut, right-hand flute spiral for standard spindle compatibility

Compatibility

Designed for use with standard 0.25-inch collet chucks and end mill holders on vertical and horizontal CNC machining centers. Rated for material grade N1BZ applications within the CoroMill Dura series.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Confirm the shank is fully seated and properly torqued in the collet or holder before operation. Verify cutting parameters against SANDVIK COROMANT application data for the specific workpiece material and machine setup.
