Product Name: MNS Five-Piece Concentric Overburden Casing Drilling System for CIR110 Hammer & 114mm Pipe
Product category: Overburden eccentric casing bit
Matched hammer: Hammer CIR110
Matched casing pipe OD: 114mm
MNS Sliding five-piece concentric overburden casing drilling system feature:
When the guide bit reaches to the rock stratum, the stabilizer rod and guide bit begin to fold, the reamer bits expand along the sliding chute and start to drill; when finished, the stabilizer rod is lifted, the guide bit is automatically separated by gravity and the reamer bits are automatically gathered, thus lifted from the bottom of the hole. This drilling system is mainly applied for 108-323mm.
