Corner Radius End Mill Overall 2-1/2 L MPN:82100821

The multilayer Duarise coating on these end mills offers high lubricity to reduce friction during milling processes and leave an excellent surface finish on the workpiece. The coating also has a high oxidation temperature and resists thermal cracking when using water-soluble oil during the milling process.

General purpose end mills are intended for milling a wide variety of common materials but are not suitable for milling hard materials like titanium or gummy materials like aluminum. Finishing end mills create a finer finish on the workpiece than roughing and roughing/finishing end mills. Carbide corner-radius end mills provide excellent wear resistance and heat resistance, and they are harder than high-speed steel, cobalt, or powdered-metal corner-radius end mills. These end mills have a coating that protects them from wear. Sometimes called bull-nose end mills, corner-radius end mills have a square nose with slightly rounded corners that help distribute cutting forces evenly to prevent damage to the end mill and extend its life. They are rotated against a workpiece to create a flat-bottomed groove with slightly rounded inside corners in milling applications that require a specific radius.
