New design concentric 3 wings casing drilling bit introduction:
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 When reaching the required drilled depth, the DTH hammer and Overburden Drill System can be withdrawn from the hole.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.

FAQ:
1. What is Symmetrix drilling?
Previously known in our industry as Concentrix, the updated Symmetrix system allows for the simultaneous casing and drilling of a hole. The system consists of three main components: pilot bit, ring bit (reamer) and casing shoe
2. Where does overburden go during a mining operation?
Overburden is used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete. Mine water is treated and then used for dust and particulate suppression, agricultural/industrial use, and as a coolant.
3. How deep can a water well be drilled?
Drilling a Water Well for household use will usually range from about 100 feet to 500 feet deep, but... When drilling a new well for your home or business, the depth of the well depends on the geology and underground water levels of the area.
