Sandvik Coromant releases CB7105 and CB7115 hard turning grades

Sandvik Coromant has strengthened its offer in the ISO H05 to H15 application area with the introduction of two hard turning grades, CB7105 and CB7115. The grades will be of particular benefit to those machining transmission components for the automotive industry, where lower cost per part can be achieved, says the company.

With CB7105, Sandvik Coromant claims to have created a grade for hard part turning that offers enhanced crater wear resistance in comparison with existing solutions, while CB7115 is designed to provide users with better fracture resistance than today’s available grades. Both are based on a PCBN grade material and coating, and feature appropriately adjusted edge preparation on the inserts.

CB7105 allows machine shops to achieve lower cost per part when used as part of a high speed machining strategy, says Sandvik Coromant. Alternatively, users of this grade can benefit from longer tool life at lower speeds.
