advantage

most favourable price and best qualtity

bearing type:

Deep blade and medial parabolic configuration ,ensure optimal bottom hole flow pattern and anti-balling .

Balanced flow hydraulics make the bit have good direction nature and enhances the drilling stability .

Medial and double row cutters design,suitable for medial soft to medial hard formations .

Formation or layer

soft ,medium soft ,hard,medium hard,very hard formation

Material

Alloy steel ,carbide ,diamond

Packing

Application

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

6,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.
