Geological Drilling Trenchless TCI Roller Cone Hole Opener
Introduction
The taper hole opener is suitable for oil drilling and geological drilling. The tapered roller hole opener has the effect of impacting, crushing and shearing the formation rock when rotating. Therefore, the tapered hole opener can adapt to soft, medium and hard formations. Especially after the emergence of jet cone drills and long nozzle cone drills, the drilling speed of roller cone drills has been greatly increased. This is a major revolution in the development history of cone openers.

Used in
Drilling, exploration, petroleum, drill bits, drilling accessories.
Cone hole opener is the most widely widely apply to oil drilling and geological drilling.
Advantages
1. Adopt floating load-bearing structure, floating elements are made of new materials with high strength, high elasticity, high temperature resistance and high wear resistance, and the surface is treated with solid lubricant.
2. New grease resistant to high temperature and wear at 250℃.
3. The steel ball locks the cone to adapt to high speed.
4. The saw blade adopts high-strength, high-toughness carbide teeth, which gives full play to the high wear resistance and excellent cutting performance of the saw blade, and extends the life of the cutting teeth of the drill.
5. Adopt high precision metal seal.
