Abstract: A clamping jaw for a tool holder chuck, wherein the clamping chuck has two clamping jaws arranged spaced apart and diametrically opposite one another relative to an axis of rotation of the clamping chuck and moveable toward and away from one another for clamping a tool shaft by moving the clamping chuck with a radial component, has a longitudinal slot having a slot mouth open toward the axis of rotation and a slot bottom. The longitudinal slot receives positive-lockingly the tool shaft and has slot flanks defining an approach angle at the slot mouth and a slot bottom angle at the slot bottom. The approach angle is greater than the slot bottom angle. The clamping jaw is manufactured with a disc milling cutter with opposed milling cutter flanks located radially outwardly and positioned slantedly relative to one another at different flank angles. The flank angles increase toward a center of the cutter body.
