Product Introduction
The T38 64mm Retrac Button Bit is a threaded top hammer rock drilling bit engineered for mining, quarrying, tunneling, drifting and construction drilling applications. With a T38 threaded connection and a 64 mm bit diameter, it is designed for compatible T38 drilling systems where reliable penetration and efficient cuttings removal are required.
The Retrac skirt design is particularly useful in fractured, fissured and broken rock formations. It helps improve borehole control and facilitates retrieval of the drill bit when drilling conditions increase the risk of jamming. The bit can be manufactured with different tungsten carbide button configurations, face designs and flushing-hole arrangements according to rock formation, drilling method and customer requirements.
