Rubber sealed roller bits main applications:
a) Adopted new alloy welding technology to improve abrasion and working life.
b) Multiple gauge structure, weld trimming teeth on the edge to enhance gauge
protection ability.
c) High precision with radial sliding, two thrust rubber sealed bearing and optimized
anti-seizure ability to avoid bits peel off.
Metal sealed roller bits main applications:
a) Adopted high- speed bearing metal sealed technology, long working life under the screw drilling condition.
b) High efficiency cutting edge and structure to improve drilling speed.
c) Cutter shell self-protection shape to reduce abrasion of detritus and unbreakable rock.
d) Best choice for directional well, horizontal drainhole and horizontal branch wells.
