Product Detail

Model No.: RZ-22

Rotary drilling tools for hard rock, roller bit, tricon

Rotary drilling tools for hard rock, roller bit, tricone bit

 

Specifications

carbide tooth three roller bit tci tricone bit, roller bits, drill bits

High temperature and wear resistance

 

 

Roller bits are mainly divided into two types:

 

i) Metal sealed roller bits

ii) Rubber sealed roller bits

 

 

Metal sealed roller bits main applications:

 

a) Adopted high-speed bearing metal sealed technology, long available time 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 directionalwell, horizontaldrainhole and horizontal branch wells.

Rubber sealed roller bits main applications:

 

a) Adopted new alloy welding technology to improve abrasion and available time.

 

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.
