IADC 7 SERIES DRILL BITS
The hard and abrasive formations Roller Cone Bit features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows.
This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations.
The HSN rubber O-ring provides adequate sealing for bearing durability.
All of our bits are manufactured according to strict standards, set forth by the American Petroleum Institute (API).
And classified according to characteristics set forth by the International Association of Drilling Contractors (IADC).
Advantage:
- Suitable for soft to extremely hard and abrasive formations.
- High temperature heat treatment forged alloy steel.
- Specifically designed tungsten carbide insert.
- Advanced synthetic grease improves bearing lubrication and reliability.
- Sealed bearing can improves bearing life for longer drilling time and more footage drilled.
- Tungsten carbide pucks added on the shirttail to protect against abrasive applications.
- Thread protected to prevent it damaged during transportation.

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.
