RUKO HGB-DIN2181-HSS-60°-MF-9x0,75mm

Machine tap for cutting metric fine threads with a 60° thread angle, manufactured from high-speed steel to DIN 2181. The M9 x 0.75 mm thread is cut with a right-hand cutting direction and three flutes, suitable for through and blind holes.

Advantages

High-speed steel provides good wear resistance and a long tool life. The bright, uncoated surface reduces chip adhesion and supports clean thread profiles. The DIN 2181 geometry ensures reliable centering and stable tapping in machine operations.
