High Performance Casing Drilling System For Mines / Quarries Alkali Resistance
Description The pilot bit is attached to any common DTH hammer shank or top hammer rod thread. The casing shoe is welded to the casing. The pilot bit and ring bit are locked together by the bayonet coupling. They drill a hole large enough to allow the casing to be pulled into the hole. The pilot bit and ring bit rotate with the drill string while the casing shoe and casing do not rotate. When required depth is reached, the pilot bit is unlocked by a slight reverse rotation of
