Bit type | IADC Code | Applicable formation | Cutting structure | Normal WOB KN/mm(bit dia.) | Rotary Speed(rpm |
THJ547G | 547 | Medium soft with low compressive strength and harder abrasive stringers,such as hard shale,mudstone,soft limestone and sandstone,etc. | Large radius scoop compacts in inner row,wedge compacts in outer row and inequable spaced compacts arrangement | 0.50~1.05 | 220~40 |
TCI bits series:
Metal-face sealed bearing TCI Bit
Cutting Structure: The durability of tungsten carbide inserts bits are improved with new formulas and new techniques for insert bit.
Gauge Structure: Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
U can choose the size below
This type of tricone bits have optimal bearing design, it can be working stably in low WOB, and high quality tungsten carbide on suiface of cones and gauge make a good wear resistance, largely extend the working life of bit.
