Rock bit catalogue
Fairly used and new Tricone and PDC bits — inspected, graded, and priced fairly. Browse by category, then send us your section and we’ll match the right bit.
Roller-cone family
Soft, unconsolidated formations
Steel-tooth cones on a non-sealed bearing — the workhorse for short, soft sections at the lowest cost per run.
Soft to medium formations
Sealed-bearing version of the milled-tooth bit — keeps grease in and cuttings out, extending life on longer runs.
Medium to hard, abrasive formations
Tungsten-carbide insert teeth on a sealed roller bearing — the most common Tricone choice for typical Nigerian sections.
Hard formations · long runs
Premium Tricone for the hardest, longest sections — sealed journal bearings give the highest hours per bit.
Fixed-cutter family
Abrasive formations · erosion-prone fluids
Tungsten-carbide matrix body with brazed PDC cutters. Excellent erosion resistance — the right call when fluids are abrasive.
Impact-prone sections · interbedded rock
Steel body is tougher under impact and rebuildable — recover cutter pockets after a run rather than scrapping the bit.
Variable / interbedded formations
Combines PDC cutters with roller cones for sections where neither alone delivers — stable in transitions, faster than tricone.
