Elongate rotary tool comprising a cermet having a Co-Ni-Fe binder

An elongate rotary tool for machining materials, the rotary tool comprising:

• an elongate body at a first end;
• a shank at a second and opposite end, the elongate body and the shank sharing a common axis;
• at least one face on the elongate body at an end opposite the shank, wherein the at least one face defines a corresponding flute extending along the elongate body toward the shank;
• at least one flank on an end of the elongate body at an end opposite the shank;
• and
• a cutting edge at a juncture of the at least one face and the at least one flank,
• wherein the at least one flank, the at least one face, and the cutting edge at the juncture thereof of the elongate rotary tool comprise a WC-cermet comprising tungsten carbide and about 0.2 wt. % to about 19 wt. % Co--Ni--Fe-binder comprising about 40 wt. % to about 90 wt. % cobalt, about 4 wt. % to about 36 wt. % nickel, about 4 wt. % to about 36 wt. % iron, and a cobalt:nickel:iron ratio comprising about 1.8:1:1.
