1.Certified by ISO9001&API
2. High quality with reasonable price
3. Fast drilling rate
4. Strong cutting structure durability
5. Different sizes as required
6. pdc drill bit,diamond bit,pdc core bit,diamond core bit,impregnated bit,pdc cutters
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.
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
balancedthat resulting better stability of the bit.
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 medium 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 technology to enhance
cleaning and cooling effects of the bit to effectively prevent bit from balling.

Advantage:
1.Optimized short parabolic profile,suitable for drilling soft to medium soft homogeneous formations.
2.Asymmetrical evolute spiral blade cutter placement makes the bit more stable during drilling.
3.Prlmary and secondary cutting structure extends bit life.
4.CFD hydraulic blance design results in nbetter bit cleanding1 and cutting removal.
5.Combined utilization of high performance PDC compacts significantly prolongs bit life.
