Overburden Drilling Systems

When drilling in soft and loose ground with scattered boulders, the soil and clay are caved in and creates difficulty to withdraw the DTH drilling equipment and lowers the drilling speed. To overcome this problem, MAXA manufactures the "Balanced Type" (BT) and "Eccentric Type" (EC) Overburden Drill Systems to enable drilling and lowering the casing simultaneously.
