WNTMASTERTOOL HSS taps Technical Information Workpieces to be plated require oversize taps. The interference depends on the coating thickness and the flank angle. at 60° Flank angle Oversize ^ 4 x coating thickness 55° Flank angle Oversize ^ 4.331 x coating thickness 30° Flank angle Oversize ^ 7.727 x coating thickness For special applications, e.g. abrasive cast iron materials or plastics other dimensions have to be chosen which are determined on previous experience. In such cases an „X“ is added to the short designation of the tolerance, e.g. ISO 2X, however the tolerance zone assignment...
