8 3/4", 12 1/4", 17" Oilfield API Drilling Rig TCI Drill Bit, Insert Tricone Rotary Bit, PDC Bit
Description of Tricone Bits:
The tricone drill bit is the most popular drilling bit in the world,it can be widely used for Oil&Gas Drilling,Mining,Water Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit and rubber sealed bit.
Advantage :
1. High temperature heat treatment forged alloy steel .
2. Carbide teeth with high strength and toughness work more efficiently
3. Tooth palm lip hard welding surface with hard alloy ,Effectively prevent the drill bit wear and tear work
4. Head OD protection to effectively reduce head wear in abrasive formation and extend bit work
5.Directional jet enlarges lateral flow area and helpful bottom hole cleaning and increase of ROP
6. Lubricating system protection of bearing and seal system of bit extend bit work life
7. API REG Connection
