Product Details

Four-flute end mills clear chips more quickly than end mills with more flutes and allow for higher feed rates than end mills with fewer flutes. They also typically have larger cores and are less prone to breaking than end mills with fewer flutes. 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 corner-radius end mills are designed to last longer and create a finer finish when used in their recommended, first-choice materials than general purpose carbide corner-radius end mills. They are used in production milling. 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.
