Bits suitable for sidetracking, horizontal well in angle building
| Bi-center bit for reaming |
 Shallow cone crown profile, improved bit bit working stable.- Specific cutters layout, enhanced bit sidetracking ability.
- Strong anti-wear gage, improved bits control.
- Different design program according to the different drilling conditions.
|  Different Design program according to the different drilling conditions.- Unique cutters layout, improved stability in working.
- Maximum reducing bit torque.
|
| Eccenter bit can drill an oversize hole than nominal size | Washover shoe for steel or non-steel materials |
 Adopted traditional bit design program- Maximum decreased the negative effect on ROP
|  Shallow cone profile, improved bits working stability.- Specific cutter layout, the black diamond is used for steel materials washover and the Ballaset is use for non-steel material washover.
- No exposure at gauge in avoid of case wearing.
- Radial fluid flow combines with the large junk slot to improve better cleaning.
- Optional pin connection.
