ABSTRACT:
A cooling fluid path formed in a calibrating tool body member includes a plurality of parallel openings extending within the body member from one side of the body member. The one side of the body member includes a slot interconnecting the parallel openings. A plate member covers the one side of the body member to close the slot to form a fluid path. A plurality of baffle members, each positioned from the plate member and across the slot and within one of the openings partially along the length of the opening, forms a serpentine fluid path back and forth within each opening on both sides of the baffle and between adjacent openings within the slot.
