2. Main Optional Features of Drill Bits
K: Cutting structures for hard plastic formations
Unique desigining parameters and lengthening insert crest enlarge rock-breaking volume at the bottom hole and increase bottom hole coverage and increase ROP of the bit in hard plastic formations
C: Center Nozzle
Center jet can avoid bit balling, eliminate resorting area of fluid at bottom hole, expedite upward flow of cuttings and improve ROP, it is suitable for drilling in soft to medium soft formations with low compressive strength and high drillability
G: Head OD Enhancement
Special inserts 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
L: Head OD Stabilization Pad
Better protection of the bit head and compensating hole can be achieved in directional and horizontal well drilling applications
There are 2 types:
1) Bit head OD is reinforced with stabilization pad and compacts
2) Spherical inserts are used on the lubrication reservoir closely
D: Gage Protection by Diamond Enhanced Cutters on Head O.D.
The gage protection is significantly reinforced by adding diamond enhanced gage compacts on head OD. Bits with this features is suitable for drilling in directional and horizontal well with high abrasive formations
