The PVD coating of indexable inserts without a hole is subject to special challenges:

1. The cutting edges point in all possible directions and require charging as freely as possible. The peak performance can only be achieved with a balanced layer thickness distribution.

2. The revenues for standard products are at a very low level. The costs for the peripheral steps such as cleaning, blasting treatment and control are increasingly coming into focus

3. The plates often have hardly any suitable surfaces for receiving them. Customers are used to the all-round coating from CVD technology and do not accept any stains or shadows from the brackets.

TongS mounts solve these challenges. Taking into account the economic aspects, TongS holders bring the cutting corners into the optimal position. In addition, the products can remain on the holders as far as possible in all production steps.
