RUKO HGB-DIN352-HSS-60°-Nr.12 Hand Tap M12 x 1.75 mm Taper Tap, HSS, DIN 352

Cutting precise internal threads in tough materials like steel or cast iron requires a tool that stays sharp and accurate. The RUKO HGB-DIN352-HSS-60°-Nr.12 hand tap is engineered for just that—a taper tap made from high-speed steel (HSS) with a ground thread for clean, reliable thread cutting.

Who is it for

Machinists, metalworkers, and maintenance professionals who need to create metric coarse threads in unalloyed and low-alloyed steels, cast iron, and non-ferrous metals. Ideal for pre-cutting internal threads before finishing with plug and bottoming taps.
