In April 2025, a construction company based in Lima reached out to us regarding a piling project in Arequipa. They were facing challenges with drilling efficiency in cohesive soil conditions and were looking for more reliable tooling solutions. In their initial inquiry, they briefly described issues such as soil clogging and tool wear, and requested augers compatible with their Bauer rotary rig. After a short exchange, it became clear that they needed a more specialized auger design to match the local geology and improve penetration rates.

First Contact: The Initial Inquiry

The client discovered our company through internet research, where our specialized foundation piling tools, particularly our drilling augers and core barrels, had garnered significant attention. In their initial email, they highlighted their need for efficient drilling tools for large-diameter soil piling work, with a strong emphasis on urgency due to their project being delayed by over three weeks. 

What stood out in their message wasn’t just the technical requirement, but the clear sense of urgency. They needed tools that could be quickly delivered, and that could match their existing drilling rigs without requiring major on-site modifications.

We responded within two hours of receiving their message and scheduled a video call for the next day. This swift communication impressed the client—they later told us they had contacted five suppliers, but only received timely and helpful responses from two.

Needs Analysis and Customized Solution

During our video consultation, our technical team conducted a detailed review of the client’s project scope and preliminary drilling data. While their initial message was brief, the conversation uncovered key specifications:

• Pile diameters of 800 mm, 1000 mm, and 1200 mm;
• Drilling depth up to 30 meters;
• Soil formations with some compacted layers, but not hard rock;
• Existing rigs were Bauer and Soilmec models.

What the client needed were Double-cut Single-flight straight soil augers, capable of efficient spoil removal in cohesive and semi-dense soils, while minimizing tool wear. Their specific requests included:

• Straight-body, double-cut augers for improved material break-up and conveyance;
• BFZ70 carbide flat cutter teeth, optimized for soil and mixed ground conditions;
• Casted Kelly boxes (130×130 mm) for seamless compatibility with their current Kelly bars;
• Reinforced structures with optional wear strips for longer tool lifespan under frequent use;
• Quick delivery and assurance of compatibility with Bauer and Soilmec rigs.

They also expressed interest in core barrels for potential use in denser zones, requesting:

• Round shank chisels,
• Adjustable cutting diameters,
• Customizable shell height and tooth layout,
• Possibility to integrate roller bits for select sections if necessary.

In response, we offered a customized tooling package centered around our standard soil auger and core barrel designs, including:

• Double-cut single-flight straight soil augers fitted with BFZ70 flat teeth, reinforced flights, and casted 130×130 mm Kelly boxes;
• Optional hard-facing or wear strips to improve performance in semi-abrasive ground;
• Core barrels equipped with round shank chisels and custom cutting diameters, with adaptability to roller bits as needed;
• Full compatibility with Bauer, Soilmec, and other major rotary drilling rigs.

We provided custom technical drawings, adapter solutions, and confirmed compatibility with their Bauer and Soilmec rigs. Our support included:

• Remote technical guidance,
• Digital training resources,
• Tool maintenance and spare part planning.

Through four rounds of technical consultation, the client was able to refine their tooling selection and drilling methodology. Our tailored approach helped them move from urgent uncertainty to confident execution, aligning our capabilities precisely with their on-site challenges and delivery expectations.

Ordering and Production Process

On April 10, the client confirmed their order for six customized soil drilling augers and related core barrel equipment. Given the urgency of their delayed schedule, our production team immediately prioritized the order. We assigned senior technicians to oversee each step, from the casting of the auger bodies to the reinforcement of the flights and Kelly boxes for heavy-duty soil operations.

To maintain transparency, we provided weekly updates with photos of production progress and quality control checks. These reports helped reassure the client that we were on track to meet both technical specifications and delivery deadlines.

Quality Control and Shipping

Before shipping, each soil auger and core barrel underwent our 17-point inspection before shipping. These checks included fit testing with 130×130 mm Kelly boxes, tooth alignment inspection, and hardness testing of wear protection strips.

For international shipping to Peru, we developed shock-resistant packaging that protected the flat carbide cutter teeth and auger flights. The goods departed on May 2 and, despite minor customs delays, our logistics team expedited clearance to ensure the tools arrived at the client’s construction site on May 12.

Client Reception and Implementation

Upon receiving the shipment, the client’s site manager Javier recorded the unboxing and initial deployment. His team quickly installed the soil augers on their Bauer and Soilmec rigs and resumed drilling.

He reported that the double-cut single-flight structure performed smoothly, especially in compacted layers where previous augers had struggled with clogging and inefficient spoil removal. With the BFZ70 flat teeth and improved auger geometry, the drilling process became significantly more stable and predictable.

“We saw an immediate improvement in spoil discharge and borehole stability,” Javier commented. “The drilling rhythm was smoother, and tool wear was much lower than what we previously experienced.”

Results and Ongoing Collaboration

By the end of the third week, the construction team had caught up with their delayed schedule. They reported:

• Over 30% improvement in daily drilling productivity;
  
  
• 50% reduction in tool wear, especially in cohesive soil layers;
  
  
• Zero incidents of tool jamming or auger deformation, thanks to reinforced flights and optimal cutter layout.
  
  

These gains restored confidence both within the client’s team and with their project owner. Their Operations Director Carlos remarked:

“The performance of these soil augers exceeded our expectations. We thank the Chinese team for delivering exactly what we needed — quickly and professionally.”
