Bit type | IADC Code | Applicable formation | Cutting structure | Normal WOB KN/mm(bit dia.) | Rotary Speed(rpm) |
THJ527G | 527 | Soft with low compressive strength and high drillability,such as shale,clay,sandstone and soft limestone,etc. | Large radius offset crested scoop compacts in inner row,wedge compacts in outer row,high compact exposure and inequable spaced compacts arrangement | 0.35~1.05 | 240~50 |
The medium formation TCI tricone bits features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard for mations. The HSN rubber O-ring provides adequate sealing for bearing durability.
Advantage of tricone rock 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.
