Description PDC Drill Bit :
Tungsten Carbide Insert (TCI) Tricone bits serve as indispensable tools for drilling operations in middle to hard rock formations, presenting a versatile range of carbide inserts meticulously designed to address the varying hardness levels of rock encountered during drilling endeavors. These inserts come in diverse shapes, including spherically shaped inserts tailored for exceptionally hard rock formations and conically shaped inserts optimized for softer rock materials..
Application:
TCI (Tungsten Carbide Insert) and Steel Tooth Tricone Bits. Each type is uniquely designed to tackle specific drilling challenges and geological formations with precision and efficiency.
TCI Tricone Bits featuring :
Tungsten carbide inserts, excel in drilling operations in middle to hard rock formations. These bits offer a variety of carbide inserts, including spherically shaped inserts for very hard rock and conically shaped inserts for softer rock, catering to the diverse hardness levels encountered during drilling endeavors.
The number of insert rows directly correlates with the application type and hole size, ensuring customizable configurations for optimal drilling performance. Operators can choose between open and sealed bearings, along with three shirttail protection options, enhancing durability and performance in challenging drilling conditions.
Steel Tooth Tricone Bits :
Steel Tooth Tricone Bit are renowned for their effectiveness in drilling applications across a spectrum of geological formations.
These bits are particularly well-suited for drilling in shale formations, soft limestone sites, fast drilling in various strata, natural gas drilling, deep wells, and abrasive formations.

Rock Formation and Roller Cone Bit Type :
According to the API ,there are different Formation from soft to middle hard to hard ,there are milled tooth and Tungstern carbid Inster (TCI ) Bit to choose , But differetn bits will match different formation which can improve the cutting of bit performance and work effeciency .
| IADC | WOB(kN/mm) | RPM (r/min) | Suitable formation |
| 417 | 0.35~0.90 | 140~70 | Very soft with low compressive strength and high drillability,such as shale,clay,sandstone and conglomerate,etc. |
| 437 | 0.35~0.95 | 140~60 | Very soft with low compressive strength and high drillability,such as shale,clay,sandstone and conglomerate,etc. |
| 517 | 0.35~1.05 | 120~50 | Soft with low compressive strength and high drillability,such as shale,clay,sandstone and soft limestone,etc. |
| 537 | 0.35~1.05 | 110~40 | Medium soft with low compressive strength and harder abrasive stringers,such as hard shale,hard gypsolyte,soft limestone,sandstone |
| and dolomite with stringers,etc. | |||
| 617 | 0.35~1.05 | 80~40 | Medium hard with high compressive strength and thick&hard stringers,such as hard shale,limestone, sandstone and dolomite,etc. |
| 637 | 0.70~1.20 | 70~40 | Medium hard with high compressive strength and high abrasiveness,such as limestone,dolomite, sandstone and chert.ect. |
