Specifications of the TCI trione bit
1) brand new drill bit
2) Size range from 3 7/8 to 26, including all IADC code.
3) Steel tooth tricone drill bit
4) Sealed type: metal sealed or rubber sealed
5) Bearing type: rolling bearing or sliding bearing
Cone bit with good structuralcharacteristics:
1 with the rolling cone bit sealed bearing, cylindricalroller body rolling groove is placed, , with better performance in use.
(2) In sub-cone bit thrust bearing surfacesrespectively antifriction treatment and hardening, hardening anti-drillprotection.
3 using can withstand 250 ° C high temperaturewear resistance of the new grease.
4 using the differential pressure limit andprevent the drilling fluid into the lubrication system.Improved conebitsoil capsule full rubber, the bearing lubrication systemprovides a good guarantee.
