steel tooth bit
1.Tricone Bit size range from 3 7/8"to 26"
2.Covers almost all IADC code.
3.Meet with API Spec7-1 Standard
Rock bit , tricone bit , steel tooth bit , milled tooth bit , cone bit , roller bit , drill cone bit
1. Steel tooth tricone bits sizes range from 3 7/8" to 26" and cover almost all IADC codes
2. The steel tooth bit are always beused in drilling soft or soft-medium formation , using fields like mining, hydrology well drilling , subterranean heat well drilling, water well drilling, oil well drilling, gas well drilling.
3.This type of tricone bits have optimal bearing design, it can be working stably in low WOB, and high quality tungsten carbide on suiface of cones and gauge make a good wear resistance, largely extend the working life of bit.
