IADC 6 SERIES DRILL BITS
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.
Application
Roller Cone Bit is one of the main tools for blast hole and well drilling, mainly used for large-scale open-pit mining, such as open-pit coal mines, iron mines, copper mines and molybdenum mines, also the non-metallic mines. With the increasing in variety of type, it’s also widely used in quarrying, foundation clearing, hydrogeological drilling, coring, tunneling in railway transportation department and shaft drilling in underground mines. The rock breakage by the tricone bit which used in mine is working with both the impact of teeth and the shear caused by slippage of the teeth, which bring high rock breaking efficiency and the low operation cost.
Common fault analysis of Tricone bits
| Common fault | Fault description | Method |
| Early wear of the shirttail | Abrasive formations, bent drill rod, seriously worn stabilizer and insufficient air for drilling rate attained etc, are all the causes which result in premature shirttail wear. In this case, the configuration of cones is good and the amount of inserts wear is small. Shairttail wear can also allow the big roller bearings to fall out resulting in bit failure. | The designer should strength the shirttail with certain measures to increase the wear-resistance capacity of shirttails. |
| Early wear and loose movement of the bearing | Excessive weight on bit, insufficent air to clean the hole and/or cool the bearing, leads to bearings overheating due to improper cooling and poor cuttings removal can shorten the service life of bit bearing. | Reduce bit pressure and increase air pressure |
| Cutting structure failure | Excessive WOB or Rotation speed; Wrong bit selection; Cuttings blowing in bad conditions caused repeating crushing. | Correctly select operating parameters and rotary types for specific working conditions |
