OD 133mm MRE Dual Rotors Overburden Casing Drilling bit CIR110 Shank

OD 133mm MRE Dual Rotors Overburden Casing Drilling bit CIR110 Shank

Description

MRE Eccentric Dual Rotors system for drilling overburden casing, Reamer bits enlarge to insert the casing pipe into the hole when rotated clockwise. Once completed, the reamer bits can be lifted up from the bottom of the hole using a drilling rig after closing counterclockwise. This kind is specifically used for diameters ranging from 89 to 323 mm.

Characteristics
