Abstract (en)

[origin: WO03083149A1] The invention relates to a hard metal or cermet cutting material for cutting chromium-alloy steel parts. Said cutting material comprises a hard phase containing carbides, nitrides and/or carbonitrides and a binder phase based on iron, cobalt and nickel. The aim of the invention is to prevent an agglomeration of the cutting material during cutting operations. For this purpose, the binder phase contains 10 % by weight to 75 % by weight of Co, 10 % by weight to 75 % by weight of Ni, 5 % by weight to 30 % by weight of Cr, > 20 % by weight to 60 % by weight of Fe, the total of Co, Ni, Cr and Fe not exceeding 100 % by weight.
