Abstract
A cutting tool for a stump cutter device, having a holder and at least one cutter insert unit, wherein the cutter insert unit has a cutter head and a shank, and wherein the cutter insert unit can be connected with the holder by its shank. To achieve a simple and cost-effective tool exchange, along with the simultaneous low wear of the contact faces, the shank of the cutter insert unit respectively has at least a tapering shank section and at least a widened shank section. The holder has a recess with protrusions corresponding to the tapering shank section and an undercut area corresponding to the widened shank section and thus provides a positive connection between the shank and the holder.
