Abstract

The invention relates to an annular tool (1) having at least one working region (4) oriented radially outward and having high wear resistance, and a clamping part (5) closer to the axis, in particular a roller bit or cutting ring for rock, in particular for tunnel boring machines, made of a material which is formed from an iron-based alloy as matrix having incorporated hard material particles, wherein the hard material particles are formed from carbide and/or nitride and/or oxide and/or boride, possibly as carbonitride or oxycarbonitride having a boron component of at least one of the elements, or in mixed form of the elements from groups 4 and 5 of the periodic system, and have a density at room temperature of more than 7400 kg/m3, preferably of more than 7600 kg/m3. The invention further relates to methods for the production thereof.
