This adaptor offers a simple solution for connecting mismatched threads in core drilling setups. It converts a 1/2" BSP female thread, typically found on drills or extensions, to a 1/2" BSP male thread for direct attachment of core bits and other accessories. Built from hardened steel, it withstands high torque and vibration while maintaining a secure, concentric fit. The adaptor can also serve as a short, rigid extension, ensuring maximum power transfer and long service life in demanding applications.
