A tool head, which is adapted to receive a cutting insert for chip removal machining, includes a basic holder which has a lower support part and an upper clamping portion defining therebetween and insert-receiving pocket. A slot extends through the basic holder at a location spaced from the pocket, wherein the clamping portion is joined to a remaining portion of the basic holder by a hinge portion about which the clamping portion is elastically displaceable toward the cutting insert. A recess extends through the basic holder parallel to the slot and in communication therewith for receiving a nut roll. A clamping screw extends through a bore of the basic holder and into engagement with the nut roll, wherein the clamping screw is operable to displace the nut roll into the slot to expand the slot and thereby elastically displace the clamping portion about the hinge and toward the cutting insert.
