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.
Product Description-----high quality PDC drill bit :
1. Cutting structure is force balanced and bit blade is asymmetrically designed so
that the load on bit is balanced that resulting
better stability of the bit.
2. Main cutter are high performance PDC cutters to insure service life of the bit while
2. Main cutter are high performance PDC cutters to insure service life of the bit while
improving ROP.
3. Cutter exposure is optimized to insure the bit can achieve higher ROP is soft to
3. Cutter exposure is optimized to insure the bit can achieve higher ROP is soft to
medium formations.
4. Shock absorbers are designed to make the bit capable of drilling through formations
4. Shock absorbers are designed to make the bit capable of drilling through formations
with hard strigers.
5. Hydraulic system of the bit is optimized using dynamic flow pattern simulation
5. Hydraulic system of the bit is optimized using dynamic flow pattern simulation
technology to enhance cleaning and cooling
effects of the bit to effectively prevent bit from balling.
