OPTIONAL FEATURES



C
 Center nozzle: center jet can avoid bit balling, eliminate resorting area of fluid at bottom hole, expedite upward flow of the cuttings and improve ROP. It is suitable for drilling in soft to medium soft formations with low compressive strength and high drillability.
D Gage protection by diamond enhanced cutters on head O.D
The gage protection is significantly reinforced by adding diamond enhanced gage compacts on the head OD. Bit with this feature is suitable for drilling in directional and horizontal well with high abrasive formation.
E Extend double nozzle
The hydraulic system of extended double nozzle can expedite upward flow of cutting , reduce regrinding of the formation and eliminate resorting area of fluid at bottom hole to achieve effective drilling.
G Head OD enhancement
Special insert are strategically arranged on head OD to reduce effectively wear of the head and improve bit's gage protection in abrasive formation or directional and horizontal wells. Improved gage protection can extend service life of the bit.
H Gage protection by diamond enhanced cutters on cone
Diamond compacts arranged in heel row or gage row for the cone can enhance gage protection and increase its working life. It is suitable for drilling in high abrasive formation, hard or extreme hard formations.
L Head OD stabilization pad
Better protection of bit head and compensating hole can be achieved in directional and horizontal well drilling applications.
There are two types:
  • Bit head OD is reinforced with stabilization pad and compacts;
  • Spherical inserts are used on the lubrication reservoir closel
