formation
Product category: Overburden casing drilling tools
Matched hammer: Hammer CIR110
Reaming Diameter(mm): 152mm
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depth, the DTH hammer and Overburden Drill System can be withdrawn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.
