Abstract: The invention relates to a cutting tool for machining processes, in essence composed of a clamping holder with a recess for accepting a support plate and with a cutting plate secured on the support plate by way of a clamping claw. It is proposed, for secure fastening of the cutting plate on the clamping holder, that an interlocking tongue-and-groove connection is used for positioning of the cutting plate on the support plate.
