Finishing Cobalt Square End Mills
Available1,149 products
Finishing cobalt square end mills create a finer finish on the workpiece than roughing cobalt square end mills. Cobalt square end mills can be used at higher speeds and are harder and more wear-resistant than high-speed steel square 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.
4-Flute Finishing Bright Finish Cobalt Square End Mills
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 bright finish on these end mills provides a smooth, polished surface.

2-Flute Finishing Bright Finish Cobalt Square End Mills
Two-flute end mills help maximize chip clearance. The bright finish on these end mills provides a smooth, polished surface.
Finishing TiCN-Coated Cobalt Square End Mills
The TiCN coating on these end mills protects them from wear and is harder and more wear-resistant than a TiN coating.
Finishing TiN-Coated Cobalt Square End Mills
The TiN coating on these end mills protects them from wear and resists impact better than TiAlN and AlTiN coatings.
6-Flute Finishing Bright Finish Cobalt Square End Mills
Six-flute end mills allow for higher feed rates than end mills with fewer flutes and clear chips more quickly than end mills with more 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.
3-Flute Finishing 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.
8-Flute Finishing Bright Finish Cobalt Square End Mills
Eight-flute end mills allow for higher feed rates than end mills with fewer flutes and clear chips more quickly than end mills with more 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.
Finishing 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.
