Description
RockForce Pin-Pin Adapters are designed to connect DTH drill tubes or drill string components with different thread sizes where both connecting ends have male (Pin) threads.
In drilling terminology, a Pin refers to a male thread, while a Box refers to a female thread. Pin-Pin Adapters provide a secure connection between two Pin-threaded components, allowing different thread sizes or configurations to be incorporated into the same drill string.
Manufactured for demanding drilling conditions, RockForce Pin-Pin Adapters provide a strong, reliable connection and efficient transfer of drilling forces throughout the drill string.
