Claw Bit Manufacturer in China
Stop wasting time and money drilling slowly through compacted backfill, hard clay and mixed ground.
Our HDD Claw Bit is purpose-built for horizontal directional drilling (HDD) pilot holes. The aggressive carbide claws don’t just scrape – they crush and fracture the formation while maintaining excellent steering control, so you can drill faster, hit your line and grade, and finish more bores per week.
Common size of Claw Bit
Find the perfect fit for any rig. We offer a complete range of common claw bit sizes, ensuring your project starts on time with the right tool for the job.
What Is a Claw Bit in HDD?
Navigating the world of HDD tooling can be complex. If you’ve ever wondered what exactly a “claw bit” is and what makes it unique, this section is your go-to guide.
A Claw Bit is a specialized HDD pilot bit designed for trenchless, “no‑dig” construction. Instead of a flat blade, it uses multiple carbide claws to aggressively cut and break through:
- Compacted fill and road base
- Stiff to hard clay
- Sandstone and soft rock
- Mixed formations with cobbles and gravel
During an HDD job, the Claw Bit is used in the pilot bore stage. It drills the initial hole along the designed path. After that, hole openers and reamers are used to enlarge the bore and pull the product pipe.
Advantages of Claw Bit
Each advantage is designed to maximize your drilling speed, extend tool life, and conquer the toughest formations.
Replaceable Carbide Cutters
The replaceable cutting tooth design means you only need to replace worn teeth, not the entire drill bit, significantly reducing your long-term operating costs (TCO) and minimizing downtime.
Rugged Heat-Treated Alloy Steel
Provides exceptional durability, withstanding high torque and impact forces, preventing bit breakage or deformation in demanding conditions. The robust, one-piece construction ensures maximum energy transfer from the drill rod to the cutting face.
Precision tapered guide surfaces
Give you superior control and precise execution of your drilling plan. Optimized geometry responds instantly to steering inputs, helping you easily navigate complex paths and avoid oversteering, even in hard, compacted soils.
Optimized flow paths and nozzles
Maintain a clean hole and efficient cutting action. This design effectively cools the cutters and promptly flushes cuttings away from the work surface, preventing balling in cohesive soils, thereby improving overall performance and bit life.

Frequently Asked Questions
Have questions? We have clear answers. Here we’ve gathered you need to know about our fly cutter reamer—so you can make your purchase with complete confidence.
A great question. The Claw bit is best suited for soft-to-medium-hard, heterogeneous formations, where its design advantages lie in breaking and poking. Tri-cone bits, on the other hand, are more suitable for homogeneous hard rock formations, where they break rock through grinding and compression.
The frequency depends on the abrasiveness of the formation. In highly abrasive sandstone or gravel formations, more frequent inspection and replacement may be necessary. The replacement process is simple and can be performed on-site with standard tools. We provide detailed replacement instructions with the drill bit.
Of course. As a source manufacturer, customization is one of our core strengths. In addition to API standard threads, we can manufacture threaded connections that perfectly match your drill pipe or probe housing based on your specific specifications or drawings, ensuring a reliable connection.
