Why Our Hard Rock Drilling Solutions Stand Out?

Engineered for Extreme Conditions

You face tough rock every day. That's why our drilling tools combine advanced matrix design with high-grade PDC cutters. This pairing creates tools that withstand the punishment of abrasive formations while maintaining cutting efficiency. Your operations benefit from fewer bit changes and more meters drilled per tool.

Precision-Matched to Your Drilling Environment

No two drilling projects are identical. We analyze your specific conditions before recommending solutions:

  • Rock characteristics: Hardness, brittleness, clay content, and fracture patterns
  • Equipment specifications: Rig type, available torque, rotational speed, and pump capacity
  • Project requirements: Borehole diameter, target depth, and formation complexity

This careful matching process ensures you get tools optimized for your exact application.

Proven Performance Across Industries

Our products serve diverse applications:

  • Coal mining operations
  • Mining exploration and probing projects
  • Water well development
  • Geothermal drilling
  • Geological prospecting programs

Each application demands specific performance characteristics. Our design team creates solutions that address your unique challenges.

Performance Advantages You Can Measure

Extended Tool Life

Compared to conventional tungsten carbide bits, our PDC arrangements final 10 to 30 times longer beneath indistinguishable conditions. This sensational enhancement diminishes your consumable costs and minimizes downtime for bit changes.

Higher Drilling Efficiency

Field information appears our instruments accomplish at slightest 60% higher penetrating productivity than routine choices. You'll total ventures speedier and decrease in general operational costs.

No Resharpening Required

Unlike traditional bits, our Hard Rock Drilling Tools don't need frequent resharpening. This saves labor time and keeps your rigs productive.

Custom Engineering Capability

Bring us your drawings, specifications, or drilling challenges. Our technical team designs custom solutions that match your exact requirements. We support both OEM and ODM partnerships.

Delivery and Support You Can Count On

Quick Turnaround: Standard generation completes in 7–10 days. We keep up adaptable stock and react rapidly to critical requirements.

Global Reach: Through organizations with worldwide express carriers, we convey door-to-door around the world. Your apparatuses arrive securely and on schedule.

Technical Organization: Our bolster doesn't conclusion at conveyance. We give progressing application direction, offer assistance troubleshoot operational challenges, and persistently work with you to optimize boring execution.

FAQ

Q: What information should I provide before purchasing to ensure I choose the right PDC bit for my needs?

A: To help our team recommend the most suitable PDC bit, please provide:

① Hardness coefficient (F-value or drillability grade) or lithology of your target rock formation

② Expected borehole diameter and depth

③ Drill rig model and key operating parameters (rotational speed, torque, pump output)

④ Application scenario (roof bolting, gas drainage, geological exploration, etc.)

⑤ Any special requirements (complex formations, fractured zones, hard interlayers)

Our technical team will offer professional selection advice and free technical support. Custom manufacturing is available for unique requirements.

Q: What advantages do PDC bits have over tungsten carbide bits?

A: Using a two-wing PDC roof bolt bit as an example, under identical rock conditions, its service life is 10 to 30 times longer than tungsten carbide alternatives. Drilling efficiency improves by at least 60%. PDC bits require no resharpening, which significantly reduces labor intensity and saves valuable rig time.

Q: What maintenance should be performed after each drilling operation?

A: After each operation, clean the bit body promptly. Check carefully for matrix detachment or steel body cracking. Inspect PDC cutter wear condition.

If the gauge protection strip is worn by more than 2/3 of its original thickness, replace the bit or have the alloy re-welded. Continued use will severely reduce efficiency and accelerate wear on core barrels and drill pipes.

When less than 1/5 of the PDC cutter volume remains, replace the cutters immediately.

Q: Drilling speed is unsatisfactory. How can I optimize drilling parameters based on rock conditions?

A: Rate of penetration depends on rock hardness, density, and abrasiveness.

① For soft to medium-hard formations: increase weight on bit (WOB) and rotational speed appropriately

② For hard rock formations: use lower rotational speed, moderate WOB, and sufficient pump output to fully utilize the shearing action of PDC cutters

Each bit size has recommended operating parameters in the product data sheet. Adjust based on penetration feedback. If you encounter abnormal vibration or sudden ROP drops, pull the bit for inspection.

Q: How can I tell the difference between normal wear and abnormal damage of a bit?

A: Normal wear shows as uniform consumption of the diamond layer with dulling of the cutting edge, but no chipping. This can be addressed through manual conditioning or cutter replacement.

Abnormal damage includes premature diamond layer separation from the tungsten carbide substrate, complete diamond layer fracture, or weld failure. These issues often result from sudden formation changes or improper handling.

To reduce abnormal damage risk: select bits matching your drill rig performance, maintain stable WOB and rotational speed, and avoid heavy impacts.
