A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing them to provide fast cuts, smooth finishes, and long tool life.
