DHD350 Flat Face Down The Hole Drill Middle and High Pressure DTH Hammer Bit
In DTH drilling, the rock drilling 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.
High Penetration Speed Dth Hammer is our company main product. After many years search, we have rich experience in development and manufacture which adopted high-quality raw materials, advanced craft technology and passed through strictly inspection, manufacturing high quality products.
