As the professional supplier of rock bits in China,we can supply all kinds of rock bits,such as PDC bits,TCI bits,rock bits,tricone bits,single cone bits,hole opener,steel tooth bits,insert tooth bits,drag bits,etc.
The description of TCI Bit
IADC Code | Applicable formation | Main characteristics of the bit | Recommended parameters | |
Cutting structure | NormalWOB KN/mm(bit dia.) | Rotary Speed(rpm) | ||
617 | Medium hard with high compressive strength and thick&hard stringers,such as hard shale,limestone,sandstone and dolomite,etc. | Large radius scoop compacts in inner row,wedge co,pacts in outer row,inequable spaced compacts arrangement,and a row of trimmers is added between gage row and heel row. | 0.50~1.05 | 80~40 |

Medium to Hard Formation TCI Bits
For medium-hard shales, limestones, sandstones and dolomites
For medium-hard shales, limestones, sandstones and dolomites
These Tri-Cone ™ Bits have moderately sharp conical or chisel inserts with a shorter extension.An increased insert count helps reduce breakage when drilling in harder formations.Full bottom hole coverage and non-uniform insert spacing results in smooth drilling at high penetration rates.
Features of TCI Bits
Short, closely spaced teeth to withstand heavier impact loads
Short, closely spaced teeth to withstand heavier impact loads
From C3 to C5 type Carbide Tri-Cones
Sizes range from 4 3/4" to 26"
