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 treatmentSpecification:PartModelPA90PA115PA140PA165PA190Casing Tube(max.O.D.)(mm)115142171195222Casing Tube (min.O.D.)
