BORED PILE SINGLE CUT SOIL AUGER

---

Overview

The Bored Pile Single Cut Soil Auger is a heavy-duty drilling tool designed for precision excavation in soft to medium-dense soils. It is a core component of bored pile foundation systems, ensuring clean, round, and stable holes for reinforced concrete piles. Manufactured under 3GEN Export’s OEM standards, this auger combines exceptional durability with engineering precision, offering global compatibility with the world’s most renowned piling rigs, including Bauer, Soilmec, Liebherr, Junttan, Casagrande, ABI (Banut & Delmag), XCMG, SANY, Woltman, Mait, TYSIM, and Fangyuan.

Unlike the double-cut version, the BORED PILE SINGLE CUT SOIL AUGER is optimized for shallow and medium-depth piling where faster rotation and high soil discharge efficiency are critical. Its single-layer cutting edge ensures smoother torque transmission, reduced wear, and minimal energy loss—making it ideal for urban construction, bridge foundations, and general civil engineering applications where speed and precision matter.

What Is a Single Cut Soil Auger?

A Single Cut Soil Auger is a rotary drilling attachment that excavates soil by using one continuous set of cutting blades welded around a central shaft. During operation, the auger penetrates the ground as it rotates, slicing through soil with its carbide-tipped teeth while lifting the loosened material upward through helical flights.

The “single cut” configuration means the auger has one set of cutting edges instead of two. This design reduces the number of contact points with the ground, enabling smoother rotation and lower torque requirements. The result is faster drilling speed, improved efficiency in non-cohesive soils, and less strain on the rig’s rotary head.

This auger is specifically designed for soft clay, silt, sand, and weathered soils, providing clean boreholes that maintain structural stability during concrete casting.

Design and Construction Features

1. Precision Single Cutting Edge

The defining feature of the BORED PILE SINGLE CUT SOIL AUGER is its single-level cutting edge, strategically angled to slice and lift soil efficiently. The geometry of the blade minimizes torque load while maximizing soil displacement, ensuring fast, smooth drilling.

2. Reinforced Helical Flights

Each auger is equipped with high-strength, continuous helical flights designed for optimal soil transport. The pitch and spacing of the flights prevent clogging, particularly in cohesive clay or damp soils, ensuring continuous material discharge.

3. High-Tensile Steel Core

The central shaft is fabricated from structural alloy steel capable of withstanding extreme torsional stress. This provides excellent rigidity and alignment during high-speed drilling.

4. Replaceable Pilot Bit

A replaceable pilot bit at the center of the auger guarantees accurate hole positioning and guides the tool during penetration. Depending on the soil condition, 3GEN Export supplies a range of pilot bits—from conical to chisel types—ensuring maximum adaptability.

5. Interchangeable Cutting Teeth

The cutting edge features bolt-on wear-resistant teeth made from tungsten-carbide steel. They can be quickly replaced on site without dismantling the auger body, reducing maintenance time and operational cost.

6. Kelly Box Connection

The upper end of the auger comes with a universal Kelly box (130 mm, 200 mm, 250 mm), making it fully compatible with global drilling rigs. This design ensures perfect torque transfer and operational safety.

7. Industrial-Grade Coating

Each auger receives a high-temperature epoxy powder coating or zinc-rich primer for corrosion protection. This industrial finish ensures long-term performance in wet, muddy, or saline environments.

How the BORED PILE SINGLE CUT SOIL AUGER Works

1. Penetration
   The auger’s pilot bit initiates the hole, guiding the central axis vertically. The single cutting edge engages the soil at a controlled angle, slicing through with minimal vibration.

2. Soil Cutting and Lifting
   As the auger rotates, the cutting edge loosens soil which is then lifted upward through the helical flights. The continuous spiral motion prevents clogging, even in damp or adhesive conditions.

3. Discharge
   Once the auger reaches the desired depth, it is lifted from the hole. The soil carried on the flights is discharged easily, leaving a clean and stable borehole ready for reinforcement cages and concrete pouring.

This three-phase operation makes the BORED PILE SINGLE CUT SOIL AUGER one of the most efficient tools in foundation drilling, combining simplicity with robust performance.

Performance Advantages

1. Faster Drilling Cycles

With a single-level cutting edge, the auger rotates faster and cuts smoother, reducing drilling time per pile.

2. Reduced Energy Consumption

The optimized geometry minimizes torque demand, extending rig service life and lowering fuel costs.

3. Clean Borehole Finish

The auger’s balanced design prevents wall collapse and ensures uniform hole diameters for concrete casting.

4. Enhanced Durability

All components—teeth, flights, and central shaft—are heat-treated for maximum hardness and fatigue resistance.

5. Simplified Maintenance

Interchangeable cutting teeth and pilot bits make maintenance quick and economical on site.
