Product Description

8-1/2 Inch 5 Blades Oil Well Drill Bit Rock Drilling Bit



1. The drill crown is a medium cast surface, suitable for generally hard to hard and highly abrasive formations.
2. The taper surface is shallow, the drill bit has good orientation, good cleaning effect and strong aggressiveness.
3. The distance between the nose and the center is moderate, so that the crown of the drill has a larger impact resistance area.
4. The angle of the PDC cutter is 20-27°, which makes the drill bit highly resistant to wear and impact.
5. The exposed design of the gauge PDC tool can increase the cutting area of the gauge part. This design will better protect the gauge effect and abrasion resistance.
6. The surface of the middle and long gauges is welded by a single row of PDC cutter gauge teeth, which enhances the wear resistance and protects the gauge better. At the same time, the design can increase the stability of the drill bit.
