ABSTRACT:
A drill stem connection system and method is shown that provides a secure hold on drill stem surfaces while unscrewing a threaded connection. Two lever arm components are adjustable to a number of possible orientations to allow for fitting the drill stem wrench in tight spaces. Concentric rotation of lever arm components facilitates connection of the lever arm components together. Configurations and methods shown provide a stable and powerful tool to loosen threaded drill stem effectively.
