VCMT / VNMG 35° Diamond Turning Inserts | Precision Machining and Wear-Resistant Turning
VCMT and VNMG are commonly used 35° rhombic turning inserts, suitable for external cylindrical, internal bore, and end-face machining. VCMT features a positive rake angle design, enabling smooth cutting and making it ideal for precision finishing and low-feed applications. VNMG has a negative rake angle structure, offering superior wear resistance and chipping resistance, making it well-suited for machining scenarios that demand high stability. A variety of flute types, R-radius options, and coating choices are available, allowing these inserts to machine steel, stainless steel, and hardened materials.
