Milling cutters have teeth that remove material from a piece of stock to create parts with complex features and shapes. They are used on CNC or manual milling machines. Chamfer milling cutters can debur parts and mill internal and external chamfers on parts. Dovetail milling cutters create dovetail slots or tapered grooves in a workpiece.
Mills with Two Milling Ends When one end wears out switch to the opposite end for two times the life of a standard cobalt steel end mill. With better heat and wear resistance than high-speed steel these cobalt steel end mills can run at higher speeds and provide better performance on hard material such as cast iron hardened steel titanium ...
