RUKO HGB DIN 2181 HSS 60° macho de roscar à máquina M20 x 1,50 rosca fina métrica

Machine tap for cutting metric fine threads M20 x 1.50 with a 60° thread angle, made of high-speed steel (HSS) and ground for precision. The tap conforms to DIN 2181 and is suitable for through holes and blind holes in unalloyed and alloyed steels up to 800 N/mm², cast iron, and non-ferrous metals.

Advantages

Ground HSS provides high wear resistance and dimensional accuracy. The 4-flute design ensures efficient chip evacuation and stable thread cutting. The metric fine thread M20 x 1.50 is ideal for applications requiring fine adjustment and high strength.
