A forming tool (1) for the production of a semifinished product or end product from a metal sheet (2) has a first tool part (3) that has an upper tool part (5), a die (6), and at least one first floating bearing (7), which attaches the die (6) to the upper tool part (5) with bearing play (18) in the bearing plane (33), for equalization of its thermal contraction or expansion, has a second tool part (4) that has a lower tool part (9), a punch (8), and at least one second floating bearing (11), which attaches the punch (8) to the lower tool part (9) with bearing play (32) in the bearing plane (34), for equalization of its thermal contraction or expansion, wherein punch (8) and die (6) work together for forming of the metal sheet (2). The two tool parts (3, 4) each have at least one further bearing (12, 13), which bearings attach die (6) and punch (8) to the upper tool part (5) or lower tool part (9) without play in the bearing plane (33, 34).
