For highest quality surfaces and maximum productivity with hardened materials: CBN indexable inserts from ARNO.
Why hard turning? Because it is very efficient, guarantees extreme tool life and excellent surface qualities, and protects the environment. Why ARNO? Firstly, because our coated CBN inserts stand out due to their incredible hardness (up to 65 HRC) and heat resistance, which is achieved via an even distribution of CBN grain and binder as well as a high degree of purity. And secondly, because ARNO offers the optimum solution for every application via seven insert types and two chamfer designs – even for extremely hard materials and the highest cutting speeds.
Ideal for hardened steel up to 52 HRC: the AH4205 type from ARNO.
If you are looking for a cost-effective alternative for hard turning, look no further – the type AH4205 is ideal for steels up to 52 HRC. Especially when combined with the NFS geometry, this type achieves the highest surface qualities down to RA 0.2 μm with excellent tool life. This is due to the very hard base substrate, a PVD multilayer coating, excellent wear and temperature resistance as well as optimum chip breakage and evacuation.
