These CCMT120404-DF diamond-shaped internal boring inserts feature KM242Z carbide grade, specially developed for 316 stainless steel machining. Equipped with optimized DF chipbreaker and high-speed design, they are fully compatible with standard CNC boring bars.
The KM242Z grade delivers excellent wear resistance under high line speed conditions, while the DF chipbreaker ensures stable chip control and strong built-up edge resistance on 316 stainless steel. It guarantees fine surface finish and consistent dimensional accuracy.
Ideal for internal semi-finishing and finishing of 316/304 stainless steel parts on CNC lathes. High-speed capability boosts machining efficiency, and extended service life reduces tool changes, lowering overall tooling costs for mass production.
