1. Special Cutting Edge: Special cutting edge can increase the cutting ability. The lifetime of tools and machines will be longer 2. Smooth And Wide Flute: Smooth and wide flute will remove the cuttings more easily 3. Heat-resistant Coating: With highly heat-resistant HELICA coating, can be used for high-speed processing 4. Bronze Coating: Under bronze coating, any abrasion is easy to be recognized 5. High Quality Raw Material: The raw material is used of high toughness, grain-sized carbon tungsten 6. Polished Surface Treatment: With high polished surface treatment, the friction coefficient could be reduced, the lathe efficiency could be improved, more production time could be saved The roughing end mills have scallops on the outside diameter which causes the metal chips to break into smaller segments. This results in lower cutting pressures at a given radial depth of cut.
