Sandvik Coromant 8037542 Corner Radius End Mill

Product Description

The SANDVIK COROMANT 8037542 is a solid carbide corner radius end mill from the CoroMill Dura series, designed for high-performance milling in metalworking and machining applications. It features a 1/4 inch diameter with a 0.015 inch corner radius and a 3/8 inch length of cut, delivering clean, controlled corner blending on finished surfaces. The ZrN (zirconium nitride) coating improves wear resistance and surface finish quality. Three right-hand spiral flutes with variable helix and variable index geometry reduce chatter and improve chip evacuation. This tool is installed by machinists and CNC operators working in production and job-shop environments.

This end mill is suited for milling non-ferrous metals, aluminum alloys, and similar materials as indicated by the N1BZ material grade classification, which targets non-ferrous workpiece materials. It is a single-end, centercutting design, allowing plunge entry and full-slot cutting. The straight cylindrical shank accepts standard 1/4 inch collet chucks and end mill holders. It is appropriate for use in vertical and horizontal machining centers, as well as manual knee mills where the setup allows for the 2 inch overall length.

Key Features

• Solid carbide construction for rigidity and wear life in demanding cuts
• ZrN coating provides enhanced hardness and lubricity for non-ferrous applications
• Variable helix and variable index flute geometry reduces harmonic vibration and chatter
• 0.015 inch corner radius protects the cutting edge and improves surface finish at workpiece corners
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Right-hand cut, right-hand flute configuration for standard spindle operation

Compatibility

Part of the SANDVIK COROMANT CoroMill Dura series. Designed for use in 1/4 inch collet chucks, end mill holders, or shrink-fit toolholders. No additional specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the tool is fully seated and properly torqued in the holder before running the spindle. Verify runout with a dial indicator before production cuts to protect the corner radius geometry. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool length offsets and establishing feeds and speeds.
