Machinists and maintenance technicians use this RUKO hand tap set for cutting metric fine threads with a 42 mm nominal diameter and 1.5 mm pitch in unalloyed and low-alloyed steels up to 800 N/mm² tensile strength. The set includes a taper tap for starting and a plug tap for finishing, both made from ground high-speed steel (HSS-G) for clean, accurate threads.
