The aggressive angle design ensures improved drilling speed, while our ISO 9001-compliant production system guarantees consistent quality you can trust.

Technical Specifications

What Makes This Roof Bit Special?

You require penetrating instruments that won't let you down in challenging underground conditions. This item is built particularly for roadway bolster, coal mining, and securing applications where unwavering quality things most.

The PDC cutter innovation gives prevalent wear resistance compared to routine bits. You'll spend less time changing bits and more time boring. The forceful point fashion optimizes rock-cutting proficiency, permitting you to total your ventures faster.

Our fabricating handle consolidates progressed topographical adjustment investigation. We ponder shake hardness, brittleness, and clay substance to guarantee this bit performs reliably over shifting arrangements counting sandstone, limestone, and rock.

Key Applications

Roadway Bolster Operations

You confront requesting conditions when penetrating grapple gaps in mine rooftops. This bit handles both strong and covered roof conditions successfully, giving the soundness you require for secure installations.

Coal Mining Projects

Fast entrance rates cruel you total more gaps per move. The amplified life expectancy diminishes your operational costs essentially, giving you superior return on investment.

Engineering Construction

Whether you're working on establishment securing or ground stabilization, this bit adjusts to complex topographical conditions with reliable performance.

Performance Advantages You'll Appreciate

Extended Instrument Life

You won't require to hinder work habitually for bit changes. The high-performance PDC cutters keep up their cutting edge distant longer than conventional choices, diminishing downtime and labor costs.

Faster Penetrating Speed

The forceful point plan cuts through shake productively. You'll take note progressed entrance rates that decipher specifically into efficiency picks up on your work site.

No Resharpening Required

Unlike tungsten carbide bits that require visit honing, PDC bits remain sharp all through their benefit life. This spares you time, labor, and honing hardware costs.

Cost-Effective Operation

While the beginning venture may be higher, the 3–5 times longer benefit life implies your taken a toll per meter penetrated drops essentially. You'll see the reserve funds include up rapidly over numerous ventures.

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 rock lithology; ② Expected borehole diameter and depth; ③ Drill rig model and operating parameters (rotational speed, torque, pump output); ④ Application scenario (roof bolting, gas drainage, exploration); ⑤ Special requirements for complex formations. Our technical team will offer professional selection advice and free support. Custom manufacturing is available.

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

A: Under identical rock conditions, PDC roof bits last 10 to 30 times longer than tungsten carbide bits, with drilling efficiency at least 60% higher. PDC bits don't require resharpening, which significantly reduces labor intensity and saves rig time. You'll experience dramatically lower cost per meter drilled.

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

A: After drilling, clean the bit body and check for matrix detachment or steel body cracking. Inspect PDC cutter wear carefully. If the gauge protection strip is worn by more than 2/3, replace the bit to avoid reduced efficiency and accelerated wear on other equipment. When less than 1/5 of the PDC cutter volume remains, replace cutters immediately.

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

A: For soft to medium-hard formations, increase weight on bit (WOB) and rotational speed appropriately. For hard rock, use lower rotational speed with moderate WOB and sufficient pump output. Each bit size has recommended operating parameters. 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?

A: Normal wear shows uniform consumption of the diamond layer with dulling but no chipping—addressable through conditioning or cutter replacement. Abnormal damage includes premature diamond layer separation, overall fracture, or weld failure, often from sudden formation changes or improper handling. Select bits matching your rig performance, maintain stable WOB and speed, and avoid heavy impacts to prevent abnormal damage.
