HARDAL Supra Endmills (TiALN) HARDAL Supra (HDS) endmills offer a new high performance alternative to conventional HSS and carbide endmills. This high speed alloy with a hardness of up to 70HRc guarantees an extremely stable cutting edge. The TiALN Black Panther coating gives the necessary resistance to heat and oxidation. This combination allows the HDS endmill to show excellent results even when run dry.
