7 1/2" 190mm 4 Wings PDC Rock Bit

 
Product Description
non-coring pdc bits
1.balanced force design
2.reasonable layout of PDC cutters
3.strong aggressiveness
4.high speed 
Characteristics of non-coring pdc bits :
-PDC cutters of different features are selected and bit profile design is optimized to suit different drilling 
applications in different formations to satisfy different requirements when drilling soft to medium hard formations.
-Cutting structure is force balanced, non-symmetrical blade and wide gage are designed so that the bit 
drills more stable and resulting longer working life of the bit.
-Better wear resistance and higher strength of the bit are guaranteed in regard to material and structure by 
using matrix body material with self-owned intellectual property rights and combining FEA analysis technology.
-Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning 
and colling effects of the bit to effectively prevent bit from balling.
-CNC sintering process uses full automatic control/ Inside and outside temperature of the bit is monitored 
during all procedures to fully embody material properties as well as ensure uniformity and stability of product 
quality.
 
Applications of non-coring pdc bits :
3 blades PDC bit is used to penetrate the degassing hole, drain hole, and grouting hole of coal mine, water canservancy and hydropower, road construction, bridge and building.  
 
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.
