High air pressure DTH drill bit water well mining rock DTH hammer button drill bit
The use of a wide range:the bit is suitable for carbonate rock, limestone, chalk, clay rock,siltstone, sandstone and other soft and hard. Each bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance. These are deigned for specific applications for all rock types,hardness's and condition.
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.
1-12 inch middle-low/high air pressure DTH hammers & bits
