for hardened steels, for cast iron
The R220.70 and the R220.74 are two face milling cutters that come fitted with PCBN face milling inserts, which are suitable for use in the high productivity face milling of grey cast iron and other hardened steels. Adjustable pockets on the devices ensure high position accuracy and security, resulting in an optimum surface finish. The R220.70 and R220.74 can be used even with applications that require higher surface finishes, as the cutter bodies have separate adjustable pockets.
The PCBN inserts can be bought with high durability and wear resistance grades, and are designed and manufactured to guarantee excellent edge quality. The R220.70 utilizes solid round inserts, while the R220.74 utilizes solid square inserts.
