RUKO HGB DIN 2181 HSS 60° MF strojný závitník M20 x 1,50 mm

Machine tap for cutting metric fine threads with a nominal diameter of 20 mm and a pitch of 1.50 mm. The HSS tool with a flank angle of 60° is suitable for through holes and blind holes in unalloyed and alloyed steels, cast iron and non-ferrous metals.

Advantages

High-speed steel (HSS) provides good cutting performance and tool life. The bright, uncoated surface allows universal use with a wide range of materials. The right-hand cutting direction and tolerance class 6H ensure precise threads.
