High Drilling Rate DTH Drill Hammer Bits DHD3.5 M30 Good Flushing Design


DTH Hammer bit is also called DTH BIT, DTH Button Bit, Down The Hole Button Bit, Rock Bit, Rock Drill Bit,

Low Air Pressure DTH Button Bit, High Air Pressure DTH Button Bit

In DTH drilling, the down the hole rock drilling 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. 

DTH Hammer drill bits are normally used on limestone,Granite, bluestone etc.the selected button inserts can let the drill bits bear any hardness rocks. also, we have special design to improve the drilling efficiency.
