THIS IS WHERE IT COMES TO THE CRUNCH. For high surface finish quality and productivity with hardened materials: CBN indexable inserts from ARNO. Why hard turning? Because it is very efficient with extremely long tool life, ensures high surface finish quality and preserves the environment. Why ARNO? Because our coated CBN grades shine due to the special hardness up to 65 HRC and heat resistance. This is obtained by the uniform distribution of CBN grain and binder and a high degree of purity. And because ARNO offers the best solution with seven grades and two chamfer designs for each application – also for extremely hard materials and high cutting speeds. If you are looking for a cost-efficient alternative for hard turning, here it is: the AH4205 grade is excellent for steels up to 52 HRC.
