High Performance Cost Ratio 26 Inch Hard Rock Hole Opener
26 Inch High Performance Cost Ratio Hole Opener For HDD Hard Rock
Drilling
Introduction
HDD hole openers range from 12 to 66, and are divided into MT type
and TCI type, which are suitable for the compressive strength of
various formations.
It is used for non-excavation horizontal directional drilling and
vertical drilling reaming of petroleum, natural gas, petrochemical,
sewage, electric power, and fiber optic pipelines.
In this operation, hole drilling is the most arduous task, and the
key to hole drilling operation is to choose a suitable hole opener
according to the operating equipment and formation.
Use a drilling machine to make holes with low torque.
Features
1. Connect the drill bit according to API standard.
2. We can adjust the bit size according to your drilling rig.
3. The best results can be obtained by using steel tooth bits in
soft formations.
