Product Introduction
The T38 76mm Retrac Button Bit is a threaded top hammer rock drilling bit engineered for mining, quarrying, tunneling, drifting and construction drilling applications. Featuring a T38 threaded connection, a 76 mm drilling diameter and a Retrac skirt design, it is built for demanding rock drilling conditions, particularly fractured, fissured and broken formations.
The Retrac design helps improve drill-bit retrieval and reduces the risk of the bit becoming stuck in unstable formations. Tungsten carbide buttons provide effective rock penetration and wear resistance, while the flushing system helps remove drilling cuttings from the borehole. The bit can be supplied with different carbide button sizes, layouts, face designs and flushing-hole configurations according to the customer's drilling equipment and rock conditions.
