Product Description
Overburden Casing System. also named Eccentric Casing System. is suitable for drilling water wells. geothermal wells. short mircopiles.medium mini-type grouting hole of building. diamond harbour project.
Economy
Eccentric is the most economical solutions because its ingenious reaming wing the bit is retrievable can be used at the next hole.
Working Principle
When drilling. the reamer bit will rotate out to enlarge the hole which enough for the casing tube slide down behind the reamer. When reached required depth. the drill pipe will drill to the reverse direction and the reamer bit will retract. It is allowing the whole drilling system to pass through the casing.
Competitive Advantage
High grade tungsten carbide inserts
Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment
