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 medium soft formations with high compressive strength and abrasive properties.such as limestone, clay rock, shale, etc.
Deep spiral blade with parabolic shaped structure and anti swirl design, Maximizing the mechanical drilling speed and stability of the drill bit.
Welding high-performance wear-resistant materials on the surface of the blade, Enhance the wear resistance and erosion
resistance of the bit.
Double row tooth structure,Reasonably configure high-quality PDC composite sheets, Optimize the tooth structure,
low density cloth teeth, improve the aggressiveness and abrasion resistance of drill bits.
Reasonably optimize hydraulic structure,Maximizing waterway design and improving debris removal efficiency,
