Three-flute end mills clear chips more quickly than end mills with more flutes and allow higher feed rates than end mills with fewer flutes. They also typically have larger cores and are less prone to breakage 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 bright finish end mills, and it resists cracking and rust better than TiN or TiCN coatings. This listing is for each.
