KAT DRILLING
1 / 2
Drifting and tunnelling tools include rods, shank adapters, couplings and bits.
We provide 11 main thread types: SR22, SR25, R25, SR28, R28, SR32, R32, SR38, R38 and T35. With diameters ranging from 38mm to 127mm, these tools are compatible with button bits, cross bits, and reaming products.
Our drifting and tunneling thread button bits are manufactured from high-quality alloy steel bars and tungsten carbides. Through professional heat treatment, these tools withstand the toughest rock drilling demands and transmit intensive impact energy into the rock with minimal energy loss.
Popular products include BIT R28 37mm, 38mm, R32 45mm, R32 48mm, and BIT R32 51mm, alongside Button Bits and Retrac Bits. We also feature H35, TUN ROD T38-Hex35-R32, Drill rod R32 H28 R28, and MF rods.
