9-7,8 IADC645 Water Well Drill TCI Rock Roller Tricone Bit Deep Oil and Gas Drilling
The TCI Tricone bits drilling for medium to hard rock formation.
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 formations. The HSN rubber O-ring provides adequate sealing for bearing durability.
The hard formation TCI tricone bits can be used to drill hard and abrasive formation. Wear resistance tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical shaped inserts are used in all rows to provide cutter durability and long life.

IADC Codes are designed to make it easier for drillers to describe what kind of rock bit they are looking for to the supplier. Such as 12 1/4" IADC617
The first three digits classify the bit according to the formation it is designed to drill and the bearing/seal design used.Bit Type and Hardness of Formation to be Drilled
First Digit: 1, 2, and 3 steel tooth bits (from softest to hardest). 4, 5, 6, 7, and 8 tungsten carbide insert bits (from softest to hardest).
Second Digit: from softest (1) to hardest (9).
Third Digit: Stand for bit feature as follows: Open Bearing Open Bearing, Air Cooled Open Bearing with Gauge Protection Sealed Roller Bearing Sealed Roller Bearing wih Gauge Protection Sealed Journal Roller Bearing Sealed Journal Roller Bearing with Gauge Protection.
