ARDURO
Reach the summit of impossibility in hard machining
Machining hardened steel at high cutting speeds and without coolants places extreme demands on tools. Therefore, selecting the correct coating is crucial. ARDURO is the latest solution to our portfolio of PVD coatings. Specifically developed for hard machining in the 55 HRC range, ARDURO sets new standards in tooling performance. This advanced coating offers exceptional abrasion resistance by combining toughness with high hardness, effectively preventing chip sticking and facilitating efficient chip removal. The innovative coating design, paired with a tailor-made layer architecture and optimized process control, withstands extreme mechanical loads during application and creates a microstructure that efficiently influences thermal conduction towards the substrate.
