End Mill, 3/8" Milling Diameter, Number of Flutes: 4, 5/8" Length of Cut, TiAlN, CEM-V-4R

The TiAlN coating on these end mills withstands high temperatures and protects them from wear. It allows the end mills to be used at faster speeds than end mills with a bright finish, and it resists cracks and oxidation better than TiN or TiCN coatings.

High-performance carbide square end mills are designed to last longer and create a finer finish when used in their recommended, first-choice materials than general purpose 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, cobalt, or powdered-metal end mills. Also called square-nose end mills, square end mills have a square nose and are rotated against a piece of stock to create a flat-bottomed groove with 90° inside corners in milling tasks. They are used for counterboring, side and face milling, and milling square shoulders.
