Product Description

Factory MEC190 Eccentric Overburden Casing Drilling System with Pilot Bit for Quarry

Product Description

Down the hole (DTH) tools manufacturer KINGDRILLING Head Eccentric Casing drilling system is made up of a pair of chain embedded to guide apparatus, and ensure the bit is not contacting and damaging the retaining ring when it is rotating. When rotated clockwise, eccentric part will be expanded to bring the casing tube into hole. After completing, eccentric bit will be closed while rotated anticlockwise, and it can be lifted up by the drilling machine. This type is especially suitable for 114-273mm in diameter.

The overburden casing drilling system is a specialized technology employed in drilling operations, particularly in challenging geological conditions where overburden layers pose significant obstacles. This innovative system integrates casing advancement with drilling, streamlining the process and enhancing efficiency in various applications ranging from mining to environmental drilling. By combining casing installation and drilling into a single operation, the overburden casing drilling system offers numerous advantages over traditional drilling methods, making it a preferred choice for projects requiring precision, speed, and cost-effectiveness.
