The PVD coating of indexable inserts with holes is subject to two major 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

Spear mounts solve these challenges. Taking into account the economic aspects, Spear 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.
