Features unequal spacing of teeth and variable leads that control chattering vibration and flute geometry optimized for high-hardness materials with enhanced chip evacuation and stiffness


Oxidation resistance evaluation (calo test crater after being held for 1 hour in the atmosphere at 1,100°C)
Oxidation resistance tests conducted under NACHI standards showed GSX II coating limits oxidation to 0.3µm from the surface. whereas coating products of competitors resulted in total oxidation of the coating layer.
Comparison of wear after side milling 70m with SKD11 (60HRC)
