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 TiN coating on these end mills protects them from wear. TiN-coated end mills can be used for milling aluminum, and they resist impact better than TiAlN and AlTiN coatings.

General purpose powdered-metal square 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. Finishing end mills create a finer finish on the workpiece than roughing and roughing/finishing end mills. Powdered-metal square end mills are tougher and less likely to break than high-speed steel or cobalt square 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.
