M (Edge Profile): Stands for a medium light-cutting geometry, ensuring low vibration and precise transitions.
PM (Chip Breaker Style): Designed for pre-machining with a demand on final surface finish, providing security on the cutting edge.
3040 (Material Grade): A highly specialized CVD (Chemical Vapor Deposition) TiCN+Al2O3 coated carbide substrate.
