RUKO HGB set maschi a mano DIN 5157 HSS-G 3/4 x 14, 2 pezzi

This 2-piece hand tap set cuts G 3/4 x 14 parallel pipe threads (BSP) in unalloyed and alloyed steels, malleable cast iron, non-ferrous metals, and plastics. Manufactured from bright HSS-G high-speed steel to DIN 5157, the set includes a taper tap for starting and a plug tap for finishing, both with right-hand cutting direction and ISO 2 (6H) tolerance for precise internal threads.

Advantages

HSS-G high-speed steel provides high wear resistance and long tool life. The bright, uncoated surface reduces friction and improves chip evacuation. The set covers both roughing and finishing in one package, ensuring consistent thread quality.
