17.5 Inch CR114 Steel Tooth Tricone Drill Bit 444.5mm with 250kg Weight for Soft Formations
The CR114 Steel Tooth Tricone Drill Bit is engineered for high-performance drilling operations in soft to medium formations. With a robust 17.5-inch (444.5mm) diameter and advanced rubber sealed roller bearing system, this drill bit delivers exceptional durability and efficiency in demanding applications.
The tricone drill bit operates through a sophisticated mechanical system where three cones rotate simultaneously around the bottom of the hole while each cone rotates on its own axis. This dual rotation mechanism ensures comprehensive rock contact and generates powerful cutting forces for efficient formation fracturing.
- Composite motion enables full rock formation contact
- Cutting teeth sequentially impact and shear formation rocks
- Drilling fluid provides lubrication, cooling, and debris removal
- Optimized for 100-300 RPM operating range
