RUKO HGB-DIN352-HSS-60°-M4x0,70mm macho de roscar manual

Cutting precise M4 threads by hand in unalloyed and low-alloy steels, cast iron, and non-ferrous metals requires a tool that stays sharp and maintains exact geometry. The RUKO HGB-DIN352-HSS-60°-M4x0.70mm hand tap solves this with a ground thread and high-speed steel construction, delivering clean, accurate threads in through holes and blind holes.

Who is it for

Machinists, metalworkers, and maintenance technicians who need a reliable single tap for manual thread cutting in materials up to 800 N/mm² tensile strength. Suitable for workshops, repair jobs, and small-batch production.
