Polycrystalline Core Bit
Features:
1、Short parabolic configuration outer cone crown design,high cutter density,significantly increases wear resistance and stability of the bit.
2、Inner and outer gauges are protected by natural diamond,which helps several-fold increasing wear resistance and stability of the bit.
3、Optimize the waterway design, benefits for the bit cleaning and cooling.
4、Suitable for coring in medium to medium hard abrasive formation.High rate of core recovery.
