RUKO HGB-DIN352-HSS-60°-5/8 UNC käsikierteitysavain, 5/8 tuuma, HSS, DIN 352

Cutting internal UNC threads by hand requires a tap that holds its edge and follows the DIN 352 standard precisely. The RUKO HGB-DIN352-HSS-60°-5/8 is a finishing tap made from high-speed steel, ground to a 60° thread angle for clean, accurate threads in general-purpose steels, non-ferrous metals, and cast iron.

Who is it for

Machinists, maintenance technicians, and metalworkers who need a reliable hand tap for producing or repairing 5/8" UNC threads. It suits workshops where manual tapping is preferred over machine tapping and where tool life and thread quality matter.
