API Borehole TCI Tricone Roller Bit IADC 635 12 1/4

Weare factory specializes in drill bits,such as tricone bits, PDC bits, HDD hole opener,Foundation roller cutters for water well, oil field, gas well,mining,construction, geothermal, directional boring, and underground foundation work all over the world. Our purpose is to sell the highquality products at the lowest possible price.
The TCI Tricone bits drilling for medium to hard rock formation.
The medium formation TCI tricone bitsfeatures 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 bitscan 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.
