DTH Hammer Button Bits have high-air pressure and low-air pressure ones. With advanced design concept, better wear-resistance, better impact-resistance, higher drilling speed and longer service life, they are widely used in large-scale open pit mining, quarry and other construction projects.
There are four types of end face design for high wind pressure DTH bits: end face convex type,End face plane type, end face concave type and end face deep concave center type. Cemented carbide mostly adopts ball teeth, spring teeth or tooth distribution mode shared by ball teeth and spring teeth.
The DTH drill bit mainly used in geological exploration,coal mine,water conservancy and hydropower ,highway ,bridge,construction etc.
DTH hammer bits are used for blast hole drilling and water well drilling project.
Working with DTH drilling pipe and DTH drill bit, mainly applied in Mining,
Marble quarry or well drilling and other construction projects.
