Master Bushing and Casing Bushing
MASTER BUSHINGS
Master bushings are designed for sq and pin drive Kelly bushings from sizes 17 1/2” to 37 1/2” rotary tables. The pin drive allows the use of extended insert bowls to meet flush with the top of table which means better slip support and preventing damage to drill pipe. The sq drive bushing has a 4” deep recess to be used with the sq drive Kelly bushings. Short and medium style slips are used in the sq drive for shallower depth and drilling.
