Abstract
A machining tool, especially a milling tool, includes a shaft-like holder defining a longitudinal axis (). A seat () is provided in the front face of the holder for a cutting plate that can be inserted into the holder. The cutting plate has a coupling part for mounting in the seat () of the holder. The coupling part has three ribs which project axially from the end surface of the cutting plate that is opposite the holder and which extend radially. The ribs are provided for engagement in complementary grooves () configured in the seat () of the holder. Their side walls (and) form driving surfaces and support surfaces, which interact for transmitting a machining torque, or as axial position safety-catch, with corresponding surfaces of the flanks of the ribs of the cutting plate. The driving surfaces and the supporting surfaces are formed by limited partial surfaces (and) of the side walls (and) of the grooves () whose other surfaces are retracted in relation to the partial surfaces (and) to form a spacing between the ribs and the walls of the grooves ().
