Product Description
DHD3.5 drill bit is a common DTH hammer drill bits model, usually
used in mining, geological exploration, water well drilling and
construction projects. Moreover, it is usually connect with the
drill pipe through API standard threads to ensure stability and
reliability.
And it use high-quality materials and advanced manufacturing
technology. So the DHD3.5 drill bit has a long service life and low
replacement frequency.
It is a kind of high air pressure dth drill bit ,our newest
design.It is also one of the most advanced DTH drill bit in the
world.
Application
Using mining industry, energy, metallurgy, geology, coal, water
conservancy, chemical industry and road construction.
