PDC mining drill bit

1,Type:matrix

2,Size: 8-1/2"

3,Blade: 5

4,Thread:4-1/2" API REG

5,PDC cutter size:16mm

6,API certification

7,suti for medium soft to medium hard homogeneous formations

8,PDC cutter type:Forced

Application: 

Suitable for medium soft to medium hard formations.

Feature:Improved support and retention

Advantage:Manage the magnitude cutter loading and bit torque.

Benefit:Improved bit durability and directional responsiveness

1,Suit for drilling medium to medium-hard formations.

2,Evolute asymmetrical blade cutter design and balanced bit load so that bit whirl is prevented .

3,Composite gage protection and low torque design improve rate of penetration .

4,CFD hydraulic balance design results in better bit cleaning and cutting removal .

5,Combined utilization of high performance PDC compacts significantly prolongs bit life .

 

 

 

Advantage:Higher nozzle counts and/or fixed ports to best serve cleaning,cooling and cuttings evacuation requirements with available hydraulic flows.Allows for higher flow rates with minimal increase in pump pressure.

Feature:Diamonds are impregnated in the matrix behind the PDC cutters

Benefit:Increased footage drilled in abrasive applications
