Evoloop® GRINDAMAX™ V3
Evoloop® GRINDAMAXTM V3 is a vanadium-based grade which has been developed to bridge the gap between conventional & Powder Metallurgy High-Speed Steels in terms of both performance and grindability. Its chemistry is a very effective combination of alloying elements allowing high wear resistance and excellent toughness.
