Deep blade and plain parabolic configuration design,enhances the offensive of the bit. Be better used for Additional Row
Double rows five blades design, maximized enhances wear resistance and stability of the bit.
Description
•CFD hydraulic balance design, benefits for the bit cleaning, cooling and anti-balling.
•Optimize the cutting structure and places high quality cutters at different points, increases wear resistance and offensive of the bit.
Optimize the width of the blade and extends the gauge reasonably, significantly enhances stability of the bit.
Enhanced Gauge
Enhanced gauge with high quality PDC cutters, offers additional protection in abrasive applications, helps several-fold increasing wear resistance and life of the bit.M
High Density Cutters
High density PDC cutting structure design,ensures efficient reaming and drilling while extending the application and performance range of casing running operation.
Hardfacing
The surface of the blade is welded by wear-resistant hardfacing material, improves wear resistance and erosion resistance of the bit.
