8-1/2 Inch 5 Blades Steel Body PDC Drilling Bit Oil Gas Rock Bits
Characteristics:
1. The crown surface of the drill bit is the middle casting
surface. It can increase the arc length in heavily worn locations
to insert more PDC cutters for better wear resistance.
2. The taper surface is shallow, so the drill has good
directionality, good cleaning effect and strong aggressiveness.
3. The center-to-center distance of the drill head is large, so
that the crown of the drill head has a larger impact resistance
area.
4. The PDC tool angle is 16-26°, which makes the drill bit have
higher cutting performance and impact resistance.
5. On the shoulder part of the bit,it is welded by double-row PDC
cutters so that they can drill and abrase simultaneously and
complement each other and work together. They undetake respectively
the cutting task so that the bits can drill in a high speed.
6. The long gauge surface is welded by double-row PDC cutter gauge
teeth so that the bit has higher abrasion resistance and better
protecting gauge effect.Meanwhile, the PDC cutters can be
effectively used to improve the bit's stability during the
drilling.
