T38 102mm Retrac Button Bit Tungsten Carbide Threaded Rock Drill Bit for Mining

Product Specification

Product Introduction

The T38 102mm Retrac Button Bit is a large-diameter threaded top hammer rock drilling bit designed for demanding mining, quarrying, tunneling, construction and rock excavation applications. Featuring a T38 threaded connection and a 106 mm drilling diameter, this Retrac button bit is built for drilling applications that require a larger borehole diameter.

The Retrac skirt design helps improve drill-bit retrieval and reduces the risk of sticking when drilling in fractured, fissured, broken or unstable rock formations. Manufactured with a durable alloy steel body and tungsten carbide buttons, it provides reliable rock penetration, wear resistance and drilling stability. Different carbide button configurations, face designs and flushing-hole arrangements can be supplied according to drilling equipment, rock formation and customer requirements.
