The HSS construction provides durability and wear resistance, while the bright finish reduces friction during threading. The hand tap design allows manual operation with a tap wrench, giving you full control in low-volume or repair work.

Ideal use cases

• Cutting internal G 9/16 pipe threads in steel, non-ferrous metals, and plastics
• Creating threads for pipe fittings, hydraulic connections, and pneumatic systems
• Repairing damaged threads or rethreading existing holes
• Workshop and maintenance environments where machine tapping is not available

Good to know

DIN 352 defines dimensions and tolerances for hand taps. The recommended core hole diameter of 21.75 mm ensures proper thread engagement. This tap is part of the Heller HSS hand tap series from RUKO.
