DTH Drill Button Bits are produced from premium quality nickel-alloy steel for increased durability and wear characteristics. Specific heat treatment standards and special “stress relief” processes ensure consistent performance.
DTH hammer bits are designed for maximum performance and hole cleaning ability and high penetration rate.
We can design and manufacture according to customer's requirement of the down the hole bits Diameter、No. air holes、carbide button shape and the face shape.
Down the hole bits advantage
1. The longer life of the drill : longer using life
2. High Drilling Efficiency : the drill button is wear -resistant ,so that the drill can always
keep sharp ,thus greatly improving the speed of the drilling
3.The drilling speed is stable : the bit is scraped and cut to break the rock
4. Good performance
5.The use of a wide range : 9-grade drill ability of rock, hard rock drilling
The application of DTH hammer
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.
