SPENTA
Head Assembly
Head assemblies connect the drill rod string to the core barrel and enable smooth rotation, fluid circulation, and efficient wireline core recovery during drilling operations.
Role in the Core Drilling System
The head assembly is a critical interface component within a core drilling system. Installed between the drill rods and the core barrel, it transmits rotational force and drilling fluid while enabling engagement with the overshot during wireline operations.
