CNMG 432 Turning Inserts For Steel

CNMG 432 steel turning inserts are known for their 80° diamond shape and double-sided design, which provides four effective cutting edges for efficient material removal. Suitable for a variety of steel materials, including stainless steel and mild steel, these inserts are ideal for medium to coarse cutting applications. They have a positive rake angle that generates low cutting forces, which helps achieve reliable performance and extend tool life. Both sides of the insert have chipbreakers to improve chip control and chip evacuation, which are critical to maintaining machine efficiency and insert life. In addition, the inserts are typically coated with a tough CVD coating that provides an excellent balance of toughness and wear resistance for a variety of cutting conditions. Insert dimensions, such as an inscribed circle diameter of 12.7 mm (0.5") and a corner radius of 0.8 mm (0.0313"), are designed to optimize cutting performance and durability.

Grade：TG4105     Color：Yellow         Hardness：P15-P30    Coating：CVD

Features：It uses a dual-structure alloy substrate with better toughness, coated with medium-thick MT-TiCN and thick a-AI2O3 coating. Recommended for general intermittent cutting of carbon steel and low-alloy steel.

Grade：TG4135     Color：Black        Hardness：P15-P30    Coating：CVD

Features：Dual-structure alloy substrate with better toughness, using MT-TiCN and thick a-AI2O3 coating. The coating is treated with stress balance technology, which has outstanding reliability and wear resistance. Recommended for processing in a wide range of steel applications.

Grade：TG4245     Color：Dual color        Hardness：P25-P40    Coating：CVD

Features：The strong and tough alloy substrate is coated with MT-TiCN + thick a-AI2O3 coating, which gives it excellent edge strength and resistance to plastic deformation, making it the first choice for processing under unstable working conditions.
