API 3 1/2 IADC 537/547 Tricone drill Bit For medium formation
| IADC | WOB (KN/MM) | RPM (r / min ) | Applicable formations | Diameter | API | Weight |
| 537/547 | 0.5~1.05 | 110~40 | Low compressive strength,medium hard formation with hard abrasive
interlayer, like hard shale, anhydrite, soft limestone, sandstone,dolomite with mezzanine, etc. | 152.4mm/ 6" | 3 1/2 | 19.5kg |
TCI Tricone bits offer a variety of carbide inserts such as spherically shaped inserts for very hard rock or conically shaped inserts for softer rock. The number of rows of inserts is directly related to the type of application and the size of hole to be drilled. There are also open and sealed bearings available as well as three types of shirttail protection to choose from. Finally, Focus rotary bits can use both fluid and air circulation.
Structural features of tricone bit
1.Cutting structure this type tricone bits:
The durability of premium tungsten carbide insert is improved with new formulas and new techniques
for insert bit.
2.Gauge structure this type tricone bits:
Multiple gaugeprotection with gauge trimmers on the heel of cone, tungsten carbide inserts and
hardfacing on the shirttail increases gauge holding capability and bearing life.
3.Bearing structure of this type tricone bits:
High precision bearing with two thrust faces. Ball lock the cone. Hardfaced head bearing surface.
Cone bearing inlaid with frictionreducing alloy and then silverplated. Abrasion resistance and seizure resistance of the bearing are improved.
4.Seal and Lubrication of this type tricone bits:
Premium Oring, optimal seal compression and curved seal structure can enhance the seal
performance.
5.Product Application this type tricone bits:
It can receive high WOB in the conventional drilling. It is suitable for various formations by matching
cutting structure with different tooth shape, tooth density and tooth exposure height.
Advantage of TCI tricone bit:
1. High-strength, high flexibility, high temperature and high wear
resistance.
2. High-precision metal seal.
3. Locking roller ball, to adapt to high-speed.
4. The use of high strength high toughness carbide teeth.
5. Hours in the rotary cone bit with the impact, crushing and
shearing the role of broken rock.
6. Cone bit to adapt to the soft, medium and hard of various strata.
7. Reasonable price and long working life.
