RUKO MGB DIN 5156 HSSCo 55° Rp 3/4 rúrkový závitník

Cutting internal pipe threads by hand or machine demands a tap that stays sharp in tough materials and produces clean, accurate threads. The RUKO MGB DIN 5156 HSSCo 55° Rp 3/4 pipe tap is made for that job. Its cobalt-alloyed high-speed steel resists heat and wear, so it holds an edge longer than standard HSS when tapping steel, stainless steel, cast iron, or non-ferrous metals.

Who is it for

This tap suits metalworkers, plumbers, and maintenance technicians who need reliable internal BSPP threads. It works in through holes and blind holes where a parallel thread with a 55° flank angle is required.
