The ISO CNMG 190616E-R:6630 turning insert is a highly advanced tool accessory specifically designed for machining steels. This double-sided negative insert features an 80° rhombic design, providing precise and efficient machining. With an inner circle diameter of 19.05 mm and a thickness of 6.35 mm, it is ideal for medium to coarse machining applications. The MT-CVD coating enhances wear resistance and durability, while the specially designed R chip breaker with a rounded cutting edge ensures optimal chip removal. This insert is suitable for cutting depths ranging from 3 mm to a maximum of 8 mm and meets the ISO tolerance class M, guaranteeing high indexing accuracy. The use of functionally graded WC-Co carbide in substrate 6630 makes it a reliable choice for demanding machining tasks.
