RUKO HGB-DIN352-HSS-M27x3,0mm käsikierretappi

Hand tap for cutting metric ISO threads M27 with a pitch of 3.0 mm, manufactured to DIN 352 from high-speed steel. The straight flute design with four flutes ensures reliable chip evacuation in through and blind holes.

Advantages

High-speed steel provides good wear resistance and cutting performance in unalloyed and alloyed steels up to 800 N/mm², cast iron, and non-ferrous metals. The bright finish reduces friction during tapping.
