Core competence diamond coating

KOMET RHOBEST is a technology and quality leader in the field of nano diamond coating. We manufacture high-grade nano-diamond-coated tools for applications in the automotive industry, aviation and aerospace industries, for mould making and the energy sector. The method used allows ultra-fine, top-quality and high-purity diamond layers to be applied even to large and complex-shaped surfaces.

Optimum adhesion of the nano diamond layer on the surface is guaranteed thanks to specially developed cleaning and preliminary treatment methods.


KOMET RHOBEST uses diamond coating particularly for tools which are suitable for machining graphite, fibre-reinforced plastics and aluminium alloys.

We place great importance on innovation and consistent further development. We have our own research department for application-related development and have been cooperating with leading international research laboratories and universities for many years.
