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 extremely soft formations with low compressive strength and high drillability, such as Clay,mudstone,
gypsum, soft limestone...
Wear-resistant coating:Carbide wear-resistant material is applied to the palm tip and the edge of the tooth palm,
increase wear resistance and life of the bit.
Carbide centralizer embedded on the surface of palm, Reduce the wear of bit grinding formations, oblique well and horizontal well
improve the life of bit.
Gauge inserts of high-quality tungsten carbide alloy, Reduce the wear of bit in grinding formations, improve the stability and life of bit.
High quality tungsten carbide tricone tooth, Reduce wear, increase the crushing capacity and life of bit.
Optimize water conservancy structure, Enhance the self-washing ability and life of bit.
