Down the Hole Bits

Our Down the Hole Bits (DTH) drill bits are designed to make your operations easier – whatever ground conditions. They are also equipped with our PowerCarbideTM inserts, which provide superior life and enhanced drilling productivity.

The KingKong DTH button bit designs are well known and extensively used around the world. Whatever conditions you are dealing with, our drill bits make the job easier. They are fitted with KingKong’s proprietary cemented carbide buttons, which are designed to drill further. The drill bit bodies are made from precision hardened nickel molybdenum steel, with a compound curve shape for faster and smoother cutting and easier removal of cuttings.
