|1. (WO2018121997) TOOL|
The invention relates to a tool for machining materials, having a main part (4, 34) and one or more blades (6, 38). The main part (4, 34) is made of a low-alloy steel. The socket (17, 39) is welded to the main part (4, 34), and the blade edges (8, 41) consist of a hard metal. The hard metal contains at least 82 vol.% of tungsten carbide and a metal binder made of a cobalt-nickel-based alloy. The hardness of the hard metal is greater than 1350 HV10. The socket (17, 39) consists of a sintered composite, and 40 vol.% to 60 vol.% of the composite is composed of a metal carbide and a metal binder. At least 95 vol.% of the metal binder consists of nickel, and the hardness of the composite is less than 800 HV10.
