150 ft-lbs will break a 3/8″ drive usually and about 300 ft-lbs will break a 1/2″ drive. These are on regular breaker bars that are partially hollow and have the little ball in the space of the head to hold the socket. A SOLID 1/2″ heat treated impact rated drive anvil will go up to about 1200 ft-lbs.
