High Quality 8 Inch PDC Drill Bit for Rock Drilling

Matrix Body PDC Drill Bit1. SOFT TO MEDIUM AND HARD FORMATION DRILLINGShort parabolic profile with lower cutter density helps to obtain better ROP in soft to medium hard formations with lower compressive strength and small hard layers.Parabolic profile with medium to lower cutter density helps to obtain better ROP in soft to medium formations with low compressive strength and small abrasive layers.Medium Parabolic profile with medium cutter density helps to obtain better ROP in medium hard formation with medium compressive strength and small abrasive layers.Parabolic profile with heavy cutter density helps to obtain better ROP and long life in hard dense formations with high compressive strength and small abrasive layers.2. DURASET GAUGESuper strong material promotes gauge wear resistance to provide long bit life.3. SPECIAL CUTTER LAYOUTBalanced force cutter layout combined with straight blade design to improve the bit stability.Balanced force cutter layout combined with backside cutter design to improve the bit life and impact resistance.4. HYDRAULICSCuttings removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each blade with the proportional fluid flow.Big junk slot with balanced hydraulics design improves anti-balling ability within high penetration.5. UNIQUE BACKRACK DESIGNThe cutter's back rake has been unique design, reducing the bit torque and increasing aggressiveness.6. UNIQUE BLADE DESIGNCurved blade design makes the bit work stability.Straight blade mixed with curved blade make the bit work stably.Size available: 6", 8-1/2", 9-1/2", 12-1/4", 16", 17-1/2"Steel Body PDC Drill Bit1.
