ABSTRACT:
A rotary tool that includes an elongate tool body and a hard insert affixed to the tool body is disclosed. The hard insert includes a WC-cermet including tungsten carbide and about 5 wt. % to 19 wt. % Co--Ni--Fe-binder. The Co--Ni--Fe-binder is unique in that even when subjected to plastic deformation, the binder substantially maintains its face centered cubic (fcc) crystal structure and avoids stress and/or strain induced transformations.
