Odex140 Eccentric Overburden Drilling System For Water Well Drilling
Product Description
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, 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 When reaching the required drilled depth, the DTH hammer and Overburden Drill System can be withdrawn from the hole.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.
Advantages
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
