The use of thick TICN and thick AL2O3 coating, has a very strong resistance to plastic deformation and cutting edge strength, is the general election of steel from finishing to rough machining. Under the high removal efficiency of cutting parameters, the performance of the cutting parameters is stable, and can achieve more green environmental protection of dry cutting. Cutting speed can be improved more than 25%, in the same cutting speed, cutting tool life can be increased by more than 30%. The product is 10pcs/box. , good overall performance, high hardness, high wear resistance and high finish. Long service life and high wear resistance. Which can be replaced in time to meet your needs., Manufacturer: MSWgjYRQ
