Abstract
The invention relates to a tool head for a woodworking machine, having a cylindrical, conical or profiled main part, which has at least two tool-receiving portions evenly distributed across its circumference for holding the cutting insert. The tool-receiving portions each have grooves tapering in the radial direction, in which one cutting insert per groove is clamped between a first side wall of the groove and a closing element. A first interlocking connection is provided between the cutting insert and the first side wall. In addition, a centrifugal wedge is arranged between the closing element and a second side wall situated opposite the first side wall of the groove. According to the invention, a second interlocking connection is provided between the closing element and the centrifugal wedge. This permits radial insertion of a cutting insert.
