Claim:
A tool head adapted to receive a cutting insert for chip removal machining, comprising: a basic holder including an insert holder formed by a lower support part and an upper clamping portion which define therebetween an insert-receiving pocket; a slot extending laterally through an outer periphery of 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 lower support part; a recess extending through the basic holder substantially parallel to the slot and in communication therewith; a nut roll positioned within the recess; a bore extending from an outer periphery of the basic holder though the slot radially inward, a longitudinal axis of the bore being oriented perpendicular to a longitudinal axis of the recess; a clamping screw extending through the bore of the basic holder and into engagement with the nut roll, said clamping screw oriented perpendicularly to said nut roll, wherein the clamping screw is operable to displace the nut roll into the slot to expand the slot and elastically displace the clamping portion about the hinge portion and toward the support part; wherein the recess is of tapering shape toward the slot.
