• Applications: Suitable for plain carbon steel, alloy steel, tool steel, stainless steel, cast iron, copper and copper alloys, and high-temperature alloys

This end mill is designed to maintain stability during heavy roughing passes while delivering reliable chip control and long tool life. The asymmetrical fine-pitch HRA profile enhances performance in deep pockets and shoulder cavities, helping to maintain consistent engagement and reduce vibration. The combination of HSS-E powder metallurgy with the Alcrona coating provides improved wear resistance and smoother cutting action across a broad range of metals. For best results, pair this tool with appropriate feed and speed settings to maximize material removal and minimize cycle times in demanding milling operations.
