Roughing Cobalt Square End Mills

Available26 products
Roughing cobalt square end mills remove large amounts of material from a workpiece more quickly than finishing cobalt square end mills. Cobalt end mills can be used at higher speeds and are harder and more wear-resistant than high-speed steel end mills. Sometimes 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.
