  • Under ReamerUnder ReamerUnder reamer is used to drilling and reaming at the same time. It’s different with the reaming drill bit which installed at the bottom of the drilling stem, it installed in the middle of drilling stem, diameter slightly larger than the bit diameter. When the following bit drilling, the reamer reaming, mend the wall at the same time. Hole opener is commonly used in drilling oblique, Shrinkage formation. When use diamond drill bit drilling, in order to prevent well diameter lessen caused by drill bit abrasion, ensure new bit can smooth down to the bottom, must install two to three diamond reamers interval in the drill stem.
