Factory Price 185mm Down hole hammer bit casing drill bit with 110/340 DTH Hammer
When drilling in soft and loose ground with scattered boulders, the soil and clay are caved in, which creates drilling difficulty to withdraw the DTH drilling equipment and lowers the drilling speed.
To overcome this problem, KINGDRILLING Eccentric Type Overburden Casing Drilling System to enable drilling and lowering the casing simultaneously. This prevents the soil from collapsing into the drilled hole.The systems are designed to drill the hole diameters bigger than the casing diameter. When reaching the required drilled depth, the DTH hammer and Overburden Drill System can be withdrawn from the hole. If the bed-rock level is reached and further drilling is needed, you can simply change the bit to a conventional DTH bit.
1. Application range
It is suitable for drilling water wells, geothermal wells, short micropiles, medium mini-type grounting hole of building, dam and harbour project.
2. Outstanding Advantage
Simple structure, easy operation, reliable quality, retrievable drilling tools and long service life.
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 drilling.
1. Hardening treatment of the part's surface:with longer operating life and excellent anti-wear properties.
2. Structural optimization:Strengthen the structural strength, easy to operate
3. Superior performance:Stable and reliable performance, high drilling speed
How to order:
