API Hejian Deris 17 1/4" TCI rock tricone drill bit for water well drilling equipment
Why tricone drill bit are most widely used
Due to impact, crushing and shearing rock breaking when roller cone rotates, the contact area between cone and bottom hole is small, the specific pressure is high, the working torque is small, and the working blade has a large total length and can be suitable for rock of various kinds.
what is the working principle of tricone drill bit
Tricone bits rely on the impact of the cone on the formation, crushing and sliding shear to crush the rock.
Size of tricone bit
17 1/2" inch (444.5 mm)
7 5/8" API reg pin
rubber /metal o-ring journal bearing
WOB (Weight On Bit)
0.35~1.05 KN/mm (bit Dia.)
110~40r/min / 220~40 r/min
Make up torque
Medium formation with high compressive strength ,and high drillability ,such as mudstone,gypsum,salt,soft limestone,etc.
The Advantages of Using a Tri Cone Over Other Drill Bits
1. Tungsten Carbide Insert (TCI) High grade tungsten carbide inserts are pressed into accurately pre-machined holes, the exposed ends of the inserts are the cutting working parts.
2. Tungsten Carbide Enhanced Inserts Arranging tungsten carbide inserts in heel and gage rows, which greatly increase gage protection ability, also prolong the service life, it is suitable for abrasive formation drilling. Diamond inserts optional upon requirement.
3. Shirttail Protection Widen and thicken hardfacing on shirttail to protect the seal.
4. Head OD Protection Special tungsten carbide inserts are arranged on head OD to effectively reduce head wear in very abrasive formations and extend the bit life.
5. Body The steel body with high strength after heat treatment
6. Nozzles The nozzles is very important part in the life of a bit, bit hydraulics are controlled through these nozzles, it is also heat treatment for more strength and stability
7. Welding The three legs welded together with quality electrodes to ensure stability in structure. To further enhance the stability, the bit goes through heat treatment to relieve stresses after welding
8. Connection Thread Threads are machined with CNC machine to keep a precision and dimension. A thin layer of heavy duty grease is applied to prevent rust.
