Sandvik Coromant 8037579 Corner Radius End Mill 1/2 in

Product Description

The SANDVIK COROMANT 8037579 is a solid carbide corner radius end mill designed for high-performance milling in metalworking and machining applications. It features a 0.5000 inch mill diameter, a 1.2500 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding cuts. The three-flute geometry supports chip evacuation while maintaining rigidity. A ZrN (zirconium nitride) coating improves wear resistance and is well suited for non-ferrous materials and high-speed finishing passes. This tool is installed and operated by machinists and CNC tooling professionals.

This end mill is built for precision milling in aerospace, automotive, die-and-mold, and general metalworking environments. The CoroMill Dura series targets applications where consistent surface finish and edge integrity are critical. The single-end, centercutting design allows plunge entry and is appropriate for slotting, profiling, and ramping operations. The 35-degree helix angle and variable index and variable helix geometry reduce chatter and improve stability during long-reach or high-feed operations. The straight-cylindrical shank fits standard ER and side-lock toolholders with a 1/2 inch bore.

Key Features

• 0.0300 inch corner radius reduces edge chipping and improves part surface finish
• ZrN coating provides wear resistance suited to non-ferrous and aluminum alloys (Material Grade N1BZ)
• Variable helix and variable index geometry minimize vibration and chatter
• Centercutting design enables plunge milling without a pre-drilled pilot hole
• 35-degree helix angle supports efficient chip evacuation in spiral flute configuration
• Right-hand cut and right-hand flute direction for use in standard CNC and manual milling setups

Compatibility

Part of the SANDVIK COROMANT CoroMill Dura series. Designed for use in 1/2 inch bore toolholders including ER collet chucks and side-lock holders. Material grade N1BZ designates optimization for non-ferrous workpiece materials.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Clean the toolholder bore and shank of any chips or coolant residue before seating the end mill. Confirm runout with a dial indicator after tightening to maintain cutting accuracy and protect the carbide substrate.
