Product Description

12 1/4 Inch 5 Blades Diamond Tipped Drill Bit Tricone Drill Bit Rock Drill Bits

1. The crown of the drill bit has a long cast surface, which is suitable for neutral and abrasive formations.
2. The cone surface is shallow and has good cleaning power.
3. The PDC tool angle is 13-16°, which makes the drill bit have stronger feedability and higher rotational speed.
4. The design of the helical blade is conducive to the exposure of the PDC tool, so that the drill bit can drill into deeper formations at a higher speed.
5. The high-edge and deep runner design enables the rock powder to be discharged from the bottom of the pit as soon as possible to prevent the drill from cutting and pilling repeatedly.
6. The middle and long gauge faces are inlaid/inlaid with double-row PDC cutter gauge teeth, which makes the drill bit wearable and has good gauge distance.
