Five-flutes 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. Refresh page to try again.
