Foundation cutter bits also known as rotary drilling rig cutting teeth, which are install in rotary piling machines and drill rigs,they are widely used in highway,railway,high-speed rail and other basic projects construction. The heads bit are made of high quality Tungsten carbide,and the body are made of the 42CrMo alloy steel. To improve the hardness and wear resistance ,the strips and buttons of tungsten carbide are welded to the conical head.
We are willing to work with friends all over the world to go forward hand in hand and seek developments together.

When it comes to building high-rises, bridges, wind farms, or heavy infrastructure, the need for deep and stable foundations is non-negotiable. That’s where a foundation drill becomes a mission-critical machine. Engineered for precision and strength, the foundation drill is essential for boring deep holes in soil, rock, and mixed geological layers.
Whether you are a civil engineering contractor or a piling equipment dealer, choosing the right foundation drill ensures long-term structural integrity and efficiency on-site.
A foundation drill is a type of heavy-duty drilling machine used in deep foundation construction to bore vertical holes into the earth for piling or caisson construction. These drills can penetrate soft soil, dense sand, gravel, and bedrock, making them suitable for a wide range of foundation systems.
Foundation drills are widely used across multiple industries and infrastructure projects:
| Industry / Application | Use Case |
|---|---|
| Commercial Building | Pile foundation drilling |
| Bridge Construction | Deep bored piling |
| Wind Turbine Foundations | Large-diameter boreholes |
| High-Speed Rail Infrastructure | Soil nailing and stabilization |
| Telecommunication Towers | Monopole installation |
Using a foundation drill guarantees reliable support for structures exposed to dynamic loads and environmental stress.
There are several types of foundation drill machines based on their drilling method and depth capability:
Kelly Bar Rotary Drills
Most common type
Ideal for diameters up to 3 meters and depths beyond 60 meters
Continuous Flight Auger (CFA) Drills
Perfect for cohesive soil
Ensures minimal soil displacement
Hydraulic Casing Rotators
Used in hard rock and urban areas
Allows precise verticality
Core Barrel Foundation Drill
Equipped with tungsten teeth
Suitable for rock penetration
All these types fall under the broader category of foundation drill machinery, each optimized for different site conditions.
| Model | Drilling Depth | Max Diameter | Torque Output | Weight |
|---|---|---|---|---|
| FDR-360 | 60 meters | 2000 mm | 360 kNm | 28,000 kg |
| CFA-180 | 22 meters | 800 mm | 180 kNm | 19,000 kg |
| RCD-500 | 80 meters | 2500 mm | 500 kNm | 32,000 kg |
A top-tier foundation drill ensures:
✅ Precise hole verticality and depth control
✅ Compatibility with multiple auger or casing tools
✅ Fuel efficiency and eco-compliance
✅ Long service life in harsh construction environments
✅ Lower operating costs due to better torque efficiency
