RUKO HGB-DIN352-HSSCo-60°-M12x1,75mm conjunto de machos de roscar manuais, 3 peças, HSS-Co, rosca métrica normal

Manual threading of metric coarse threads in tough materials demands tools that stay sharp and resist wear. This hand tap set from RUKO GMBH is made from high-speed steel with cobalt (HSS-Co), providing the durability needed for threading unalloyed and low-alloyed steels, cast iron, and non-ferrous metals up to 900 N/mm². The set includes three taps—taper, second, and bottoming—for cutting full threads in through holes or blind holes.

Who is it for

Machinists, metalworkers, and maintenance technicians who need reliable hand taps for creating or repairing M12 coarse threads in a variety of metals. Suitable for manual threading operations where precision and tool life are essential.
