Product Description
CNMA 80° Rhombic Turning Insert with Flat Chipbreaker for Cast Iron Machining
This CNMA 80° rhombic turning insert features a flat chipbreaker geometry specially optimized for cast iron machining. Adopting negative rake structure with strong edge toughness, the insert delivers excellent chipping resistance and stability during heavy-duty turning, interrupted cuts, and rough machining of grey cast iron and ductile iron. The flat chipbreaker design simplifies chip flow for short brittle chips while maximizing cutting edge strength, making it a cost-effective and reliable solution for general iron turning applications.
