Product Description

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 to medlum hard formations with abrasive properties.such as limestone, sandstone. shale, etc.
Deep blade parabolic shaped structure, anti rotation design, Increase the depth of the blades, reduce torque, improve the drilling depth,
mechanical drilling speed, and stability of the drill bit.
Welding high-performance wear-resistant materials on the surface of the blade,Reasonably configure high-quality PDC composite
sheets, Enhance the wear resistance and erosion resistance of the bit, Optimizing the tooth structure to improve the attack and
abrasion resistance of the drill bit.
Strengthening gauge with PDC composite sheets,Reduce the wear and tear of rocks on diameter preservation,increase the
wear resistance and stability of diameter preservation, improve the service life of drill bits.
Hydraulic structure optimization,Flow field design at the bottom of the well, conducive to the migration of rock debris and
the prevention of mud bags.
