FKSeries
Air Cooling Roller Bearing Bit
FK Series Tricone Bit Diameter from 7 7/8-12 1/4 inch,IADC Code from 412 to 732.
Cutting Structure
Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new formula and new techniques of insert bit.
Gauge Structure
The leg and shirttail is hardfacing and tungsten carbide insert, the enhanced heel and hardfacing can better protect the gauge.
Bearing Structure
Air cooling roller bearing package, the ball can tightly locked the cone, optimized space between shirttail and cone R-slot lowers the accident of cone-dropping to minimum.
Product Predominance
It is applied for mining operation.
