Abstract

The invention relates to a fixing arrangement for holding a cutting tooth on a cutter. The cutting toot comprises a tool head and a shank. The shank is accommodated in a shank-receiving element of the cutter or a holder connected to said cutter. One or several bearing surfaces of the cutting tooth lies/lie on support surfaces of the cutter. The cutting tooth can be supported in a stable and reliable manner by inclining the support surfaces and the bearing surfaces in a peripheral direction and by providing the cutter with a shoulder which is arranged in the direction of the cutter in an offset position in relation to the bearing surfaces, said shoulder being associated with the cutting tooth at a distance therefrom.
