The nACRo coating on these end mills protects them from wear. It is harder and more resistant to high heat than TiAlN, TiCN, AlTiN, and AlCrN coatings.

High-performance carbide ball end mills are designed to last longer and create a finer finish when used in their recommended, first-choice materials than general purpose ball end mills. They are used in production milling. Roughing/finishing end mills remove large amounts of material and create a smooth finish on the workpiece at the same time. Carbide end mills provide excellent wear resistance and heat resistance, and they are harder than high-speed steel or cobalt steel end mills. Ball end mills have a rounded nose that creates a round-bottomed groove in milling tasks. Also known as ball-nose end mills, they are rotated against a workpiece to make round-bottomed slots and pockets or mill complex shapes without sharp corners.
