Drifting and tunnelling tools include rods, shank adapters, couplings and bits. We provide a comprehensive range of high-performance components designed for the most demanding underground environments.
Our thread selection covers 11 major standards: SR22, SR25, R25, SR28, R28, SR32, R32, SR38, R38, and T35. With diameters ranging from 38mm to 127mm, these tools are fully compatible with button bits, cross bits, and reaming products.
The thread button bits are manufactured from high-quality alloy steel bars and premium tungsten carbides. Through advanced heat treatment, these bits withstand the toughest rock drilling demands, transmitting intensive impact energy into the rock with minimal energy loss. Popular specifications include the R28 37mm/38mm, R32 45mm/48mm/51mm, as well as Button Bits, Retrac Bits, and various drill rods like the H35, TUN ROD T38-Hex35-R32, and MF rods.
