CIR90 Low Air Pressure DTH Drill Bit Tungsten Carbide 90mm - 130mm Bit Dia

In Down the hole drilling, the DTH hammer bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.

We select best steels from Sweden Ovako factory or Baogang, the Tungsten carbide inserts are top material treated with hot insert technology.
