Browse our top-tier core drilling rigs, horizontal directional drills, and custom structural piling tools engineered for maximum efficiency.
In soft-to-stiff cohesive soil formations, traditional drilling tools face extreme operational stress due to the adhesive and plastic properties of clay. A highly engineered Clay Auger acts as a primary rotary tool to break cohesiveness and transport soil upward without creating structural blocks within the borehole.
Key design features of a professional clay auger include the pitch spacing of the flights, the geometry of the progressive pilot bit, and the thickness of the alloy steel plates. Without these targeted design elements, heavy drilling rigs face the common challenge of "balling up," where clay sticks to the center shaft and flights, causing hydraulic strain, excessive drag, and severe drops in drilling efficiency.
Sinovo heavy-duty clay augers are designed using high-strength steel (typically Q355B or wear-resistant Hardox equivalents) and built to withstand torque peaks from powerful rotary drives, ensuring continuous stability and durability under variable structural loads.
Features a wide pitch configuration and customized double-flight or single-flight structures to facilitate smooth cutting discharges and minimize structural suction.
Hard-faced welding runs along flight edges and highly exposed stress zones to prevent abrasion and extend operational lifespan in gritty or hard clay layers.
Compatible with international standard Kelly bar sizes (such as 130mm, 150mm, and 200mm square connections) to guarantee a direct, seamless match with global rotary rigs.
SINOVO heavy-duty drilling tools are customized to match exact geological conditions and rig capacities. The pricing model depends on tool diameter, plate thickness, Kelly box size, and type of ground engagement teeth (e.g., flat teeth, rock teeth, or custom tungsten carbide teeth). Below is a guide to technical parameters and pricing factors:
| Drilling Diameter (mm) | Typical Flight Thickness (mm) | Kelly Box Connection (mm) | Suitable Soil Conditions | Estimated Base Price Index |
|---|---|---|---|---|
| Φ600 - Φ800 | 16 / 20 | 130 x 130 / 150 x 150 | Soft to medium-stiff cohesive clays | Request Dynamic Quote |
| Φ1000 - Φ1200 | 20 / 25 | 150 x 150 / 200 x 200 | Stiff clay, sandy silt mix | Request Dynamic Quote |
| Φ1300 - Φ1500 | 25 / 30 | 200 x 200 | Dense cohesive soils, dry clay layers | Request Dynamic Quote |
| Φ1800 - Φ2000 | 30 / 40 | 200 x 200 / Custom Octagonal | Highly consolidated clay, deep marine silts | Request Dynamic Quote |
*Note: The actual quote for custom clay augers will vary depending on raw steel market fluctuations, shipping destinations, import tariffs, and specific custom requirements (e.g., hardfacing strips, specialized pilot bits). Contact our technical sales team for a formal project quote.
