Product Description

Product Description

Attributes of PDC Drill Bits:

1. Stability: PDC bits have a tendency to vibrate or drill laterally away from the bit centerline, which is influenced by the bit profile .
2. Steerability: The ability of the bit to maintain a desired drilling direction is affected by the profile .
3. Cutter Density: The number of cutters on the bit, which can impact the rate of penetration (ROP) and cleaning efficiency .
4. Durability: PDC bits are known for their longevity, maintaining sharpness and resisting wear .
5. Rate of Penetration (ROP): Influenced by the bit's hydraulic efficiency and cutter loading .
6. Cleaning Efficiency: The ability of the bit to remove cuttings, which is directly related to the hydraulic flows across the bit face .
