A piston for a TCM has a central bore and a nozzle arrangement that carries a cooling liquid that is directed against the chip that the piston contacts. The bore extends from the hat end of the piston to a short distance from the face of the piston that contacts the chip, and at this point the bore branches into a cone-shaped array of nozzles that emerge from the face of the piston in a circular configuration. As is conventional, the chip end of the piston has a slightly concave shape, and the nozzles emerge from the piston at a point where the face of the piston is curved slightly away from contact with the chip. Liquid is distributed to each piston through openings located at the end of the cylindrical cavities which house the pistons. The liquid cools both the piston and the chip.
