KAT DRILLING
1 / 2
Drifting and tunnelling tools are essential components in modern excavation, including rods, shank adapters, couplings, and bits. These tools are engineered to meet the most demanding geological conditions.
We support 11 primary thread types: SR22, SR25, R25, SR28, R28, SR32, R32, SR38, R38, and T35. With a diameter range of 38-127mm, these tools are fully compatible with button bits, cross bits, and reaming products.
Our thread button bits are manufactured using high-quality alloy steel bars and tungsten carbides. Through advanced heat treatment, these products withstand the toughest rock drilling demands and transmit intensive impact energy into the rock with minimal energy loss.
Our R32 and SR32 drill rods, including the H35, TUN ROD T38-Hex35-R32, MF rod, and Drill rod R32 H28 R28, are widely recognized for their durability and high-performance capabilities in drifting applications.
