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 When reaching the required drilled depth, the DTH hammer and Overburden Drill System can be withdrawn from the hole.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. High drilling efficiency, the drilling button is wear-resistant and can always keep sharp, thus greatly improving the drilling speed.
2. The drilling speed is stable. Drill bits are scraped off to break up the rock.
3. A good drill bit has strong wear resistance, good diameter protection, and can effectively use the cutting teeth.
