The cutting ring (1), for disk rollers of partial and/or full cutting machines in tunneling and the like, has a base ring (2) of steel or similar material. The cutting ring has a closed hard metal ring (4) at the outer mantle surface (3) of the base ring. The hard metal ring is composed of segments of a cobalt and/or nickel alloy. The base ring has two pyramid projections (7), to hold the hard metal ring between them, soldered in place. |
