Square End Mill, 1/4" Milling Diameter, Number of Flutes: 4, 3/4" Length of Cut, TiAlN, HP400

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.
