Audited Supplier 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 When reaching the required drilled depth, the DTH hammer and Overburden Drill System can be withdrawn from the hole.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.
Eccentric casing drilling system allows you to drill in all types of formations, even those with large stones. This method is based on a guided drill bit and an eccentric reamer, which drill a hole slightly larger than the outer diameter of the casing together. This allows the casing to follow the drill bit down. When using KINGDRILLING, some of the impact energy is transferred to the casing through the shoulder on the guide device, which in turn impacts the special casing shoe at the lower end of the casing.
