Title: MACHINING TOOL
Abstract:
The invention relates to a machining tool (1; 100) for materials containing metal, comprising a basic material consisting of a hard metal (4) which has particles of a resistant material (6) embedded into a ductile metallic binder (5). The metallic binder (5) is a Co-Ru alloy and the particles of resistant material (6) are at least predominantly made of tungsten carbide, with an average tungsten carbide grain size of 0.1 - 1.2 µm. The hard metal has a (Co + Ru) content of 5-17 wt.% of the hard metal, an Ru content of 6-16 wt.% of the (Co + Ru content), a Cr content of 2-7.5 wt.% of the (Co + Ru) content, a content of Ti, Ta and/or Nb each of < 0.2 wt.% of the hard metal, and a V content of < 0.3 wt.% of the hard metal.
