Design Features of PDc Oil Drill Bits
1, Blade Design
The design of the blade widens the flow channel of the dril bit, effectively prevents mud clogging, and the asymmetrical blade layout reduces the wear of cutting teeth.
2,Gauge Protection Design
he design of spiral gauge protection surfaces improves tooth density, reduces the effective gauge length of the dril bit,increases the base of the qauge protection surface, and reduces the torgue of the drilbit, This extends the lifespan of thedrill bit and improves its control over water holes.
3,Raised Blade Design
This design provides the drill bit with a stronger attack driling speed, bringing users a more efficient drilling experience.
4,Multi-row Tooth structure Design
This design maintains efficient cutting ability while reducing the risk of wear and damage to the drill bit, effectively improving the stability and impact resistance of the drill bit.
5,Anti-Rotation Design
We have adopted an anti-rotation design to enhance the stability of the blade and increase the driling speed.

| FEATURE | |||||
| Suitable for soft formations, such as clay rock, sandstone, shaping mudstone, etc. | |||||
| Deep blade with long parabolic shape structure and anti swirl design, Maximizing the mechanical drilling speed and stability of the drill bit. | |||||
| High quality composite sheet gauge preservation, reduce gauge wear and increase the wear resistance and stability of drill bit gauge retention. | |||||
| Welding high-performance wear-resistant materidls on the surface of the blade, Enhance the wear resistance and erosion resistance of the bit. |
|||||
| Double row tooth, Reasonably configure high-quality PDc composite sheets, 0ptimize the tooth structure, improve the aggressiveness and abrasion resistance of drill bits. |
|||||
| Strengthening gauge with PDc composite sheets, Reduce the wear and tear of rocks on diameter preservation, increase the wear resistance and stability of qauge, improve the service life of drill bits. |
|||||
| Hydraulic structure optimization, Flow field desian at the bottom of the well is beneficial for the migration of rock debris and the prevention ofmud bags. |
