We are capable to design and manufacture according to customer's requirement on the Bit DiaNo., Air holes, carbide button shape and the bit face shape. High air pressure and low air pressure. Thanks to our long year experienced technicians and engineers in the field, whom make this into reality and meet the clients' demand accurately.
All hammer and bits are compatible with many products manufactured by , Atlas Copco, etc, all our products are widely used in mining, tunneling, quarrying, construction, and civil engineering project.
APPLICATION RANGE: Widely used for drilling water wells,geothermal wells,short mircoplies,medium mini-type grouting hole of building,damand habour project.
OPERATION GUIDELINES: 1. When drilling starts, the reamer swings out and reams the pilot-hole wide enough for the casing tube to slide down behind the drill bit assembly. 2. When the required depth is reached, rotation is reversed carefully, whereupon the reamer swings in, allowing the drill bit assembly to be pulled up through the casing. 3. Casing tubes that are to be left in the drill hole should be sealed at the bottom of the hole by means of cement grout or some other sealing agent. 4. Drilling continues to the desired depth in the bedrock using a conventional drill string.
