Roughing Cobalt Square End Mills
Available57 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.
Length of Cut
3-Flute Roughing Bright Finish Cobalt Square End Mills
Three-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 bright finish on these end mills provides a smooth, polished surface.

Roughing TiAlN-Coated Cobalt Square End Mills
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.
