A can forming tool pack 2 includes internally cooled die modules 4, 6, 8. Each die module includes at least one die nib 14, 16, 18, 20, 22 held in a case. Fluid cooling medium is supplied to multiple inlets 24, 26, 28, 30 provided circumferentially in each case. The cooling fluid is channelled from the inlets through clearances 42, 44, 46, 48, 50 between an outer surface of the die nib and the case to cool the die nib. Outlets 34, 36, 38, 40 are spaced circumferentially around the case to return the cooling fluid to the medium supply
