Cor Rad End Mill 1/4 Carb 0.0200 rad MPN:GEC-250-4-020X

The AlTiN coating on these end mills protects them from wear and is more resistant to high heat than TiN, TiCN, and TiAlN coatings. AlTiN-coated end mills are used for milling hard and abrasive materials.

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. Roughing/finishing end mills remove large amounts of material and create a smooth finish on the workpiece at the same time. 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. 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.
