RUKO HGB handtapset M30 x 1,5 mm DIN 2181, 2-delig, HSS-G

Cutting precise metric fine threads in tough materials demands a tap that stays sharp and accurate. The RUKO HGB hand tap set provides two high-speed steel taps for M30 x 1.5 mm threads, conforming to DIN 2181, so you can produce clean internal threads in steel, cast iron, and non-ferrous metals without premature wear.
