Inserts Oil Well DTH Hammer Bits Reaming Tungsten Carbide DTH Hammer Button Bits

In Down the hole drilling, the DTH 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.

DTH bits are paired with their corresponding hammers (by drilling hole diameter and spline configuration). Customers can customize their DTH bits in various ways, such as changing the tungsten carbide insert profile (spherical, ballistic, etc.), face profile (flat face, concave, convex, etc.), and flushing holes.​

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.
