Threaded Cross Bit

Description of Threaded cross bit:
Same as tapered cross bits, cross bits have an excellent drilling penetration, also they can be used in very hard or hardest rock formation. Like threaded button bits, we have different shape design of cross bits, one is standard one, also named cylinder button bits, another one is retrac button bits. Usually retrac cross bits are used for some fractured rock formation, such cross bits can make drilling hole very straight because of special wings outside of cross bits bodies and such cross bits can be easily pulled out from drilling holes after finish drilling. Our cross bits diameters are from 38mm to 127mm, and different threads are available, like R22, R25,R32, R38, T38,T45,T51, SR28,SR32,SR35, ST58, ST68,etc.
