With over 10 years of manufacturing expertise, we've engineered this bit to work efficiently in rock formations up to f=10 hardness. You'll benefit from 10–30 times longer service life compared to traditional tungsten carbide bits, plus at least 60% higher drilling efficiency. Our standard production lead time is just 7–10 days, and we support full OEM/ODM customization to match your exact drilling requirements.

Technical Specifications

What Makes Our Spiral Rib Design Different?

The rib winding structure isn't fair around looks—it's built to illuminate genuine penetrating challenges you confront each day.

Enhanced Cutting Efficiency

The winding channels direct cuttings absent from the cutting confront rapidly. This avoids re-cutting and keeps your penetrating speed consistent.

Better Cooling Performance

Drilling liquid streams through the winding grooves more effectively. Your bit remains cooler, and PDC cutters final longer beneath persistent operation.

Improved Directional Stability

The rib plan gives adjusted contact with the borehole divider. You get straighter gaps with less deviation—critical for exactness investigation work.

Smooth Borehole Walls

The winding design diminishes vibration and makes cleaner gap surfaces. This implies higher center recuperation rates and way better test quality for your topographical investigation.

Where You Can Use This Bit?

Coalfield Exploration

Perfect for distinguishing coal creases and understanding subsurface structures. The item keeps up solidness indeed in layered arrangements with changing hardness.

Gas Seepage Operations

Underground coal mines require solid instruments that won't come up short mid-operation. Our bit conveys steady execution in gas waste boreholes where downtime costs you cash and safety.

Dewatering Projects

When you require to evacuate groundwater some time recently mining, smooth boring and directional precision matter. This bit makes a difference you total dewatering gaps speedier with less instrument changes.

Geological & Hydrological Drilling

For investigation ventures where center quality decides venture victory, you require amazing test recuperation. The winding plan ensures your center whereas penetrating through blended arrangements.

Key Performance Features

Smooth Drilling Action

Reduced vibration means less wear on your drill rig and longer equipment life. You'll notice the difference in operator comfort during extended drilling sessions.

Excellent Directional Control

The balanced rib design keeps your bit on track. Less deviation means fewer abandoned holes and better data from your drilling program.

Superior Core Recovery

Clean cutting action and efficient chip removal protect your core samples. You get the geological information you need without re-drilling.

No Resharpening Required

Unlike tungsten carbide bits, PDC cutters maintain their cutting edge throughout their service life. This saves you labor costs and keeps your rig productive.

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 the following information:

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

② Expected borehole diameter and depth

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

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

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

Once we receive this information, our technical team will offer professional selection advice and free technical support. Custom manufacturing is also available.

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

A: Take the two-wing PDC roof bolt bit as an example. Under identical rock conditions, its service life is 10 to 30 times longer than that of a tungsten carbide bit, and drilling efficiency is at least 60% higher. Additionally, PDC bits do not require resharpening, which significantly reduces labor intensity and saves rig time. Industry data shows that PDC bits typically last more than 10 times longer than tungsten carbide bits.

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

A: After each drilling operation, clean the bit body promptly. Carefully check for any abnormalities, such as matrix detachment or cracking of the steel body. Also inspect the wear condition of the PDC cutters.

If the gauge protection strip is worn by more than 2/3 of its original thickness, continued use will severely reduce drilling efficiency and accelerate wear on the core barrel and drill pipe. In that case, replace the bit or have the alloy re-welded.

When less than 1/5 of the PDC cutter volume remains, do not continue using the bit—replace the PDC cutters immediately.

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

A: Rate of penetration (ROP) depends closely 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 a lower rotational speed, moderate WOB, and sufficient pump output to fully utilize the shearing and crushing action of the PDC cutters

Each bit size has a recommended range of operating parameters—refer to the product data sheet for details. As a general rule, adjust parameters based on penetration feedback. If you encounter abnormal vibration or a sudden drop in ROP, pull the bit out for inspection.

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

A: Bit failure typically appears as diamond layer spalling, chipped cutters, lost cutters, or erosion of the cutter studs.

Normal wear usually shows as uniform consumption of the diamond layer, with the cutting edge becoming dull but not chipped. This can be addressed by manual conditioning of the bit or by replacing the PDC cutters.

Abnormal damage includes premature separation of the diamond layer from the tungsten carbide substrate, overall fracture of the diamond layer, or weld failure. These issues are often caused by sudden changes in formation or improper handling.

To reduce the risk of abnormal damage, operators should select a PDC bit that matches the performance of their drill rig, maintain stable WOB and rotational speed while drilling, and avoid heavy impacts as much as possible.
