Product Description

4 5/8 Inch Directional Drill Bit 4 Blades Well Drill Bits PDC Cuttter



1. The bit crown is a flat polished surface, suitable for hard non-abrasive formations. Can be used for strongly directional operations with good directionality.

2. The top of the drill bit is a shallow conical surface, which has good orientation, strong cleaning power and strong aggressiveness. 4 nozzles on the drill bit help remove cuttings from the bottom of the hole.

3. The drill bit is inserted into the PDC cutter in a counterclockwise staggered manner, so that the cutter can cut any area of the well with good cutting effect, and also reduces the number of drill bits to drill a hole. And the bit is at high speed and more stable.

4. The high-impact tool is embedded symmetrically on the drill. Caster angle is 13° to 16°. Knife model 1308 is very aggressive.

5. The blade of this drill is designed as a micro helix. The gauge surface is inlaid/inlaid with PDC knife gauge teeth to enhance the wear resistance and improve the gauge effect. Therefore, the tool can be fully utilized to improve the stability of the drill.
