Frequently Asked Questions

Is Reverse Circulation Hydro Drilling Rig for Deep Water Wells, Borehole Surveying, and Subsurface Resource Assessment worth the money?

For its intended professional user—yes, it can be. The value isn’t just in the rig itself, but in the superior geological data it produces. If clean samples directly impact your project’s financial decisions (like defining a mineral resource), the return on investment justifies the cost. For casual or non-sampling work, it is not cost-effective.

How does it compare to a conventional percussion drill?

The key difference is sample quality. A conventional drill mixes cuttings from the entire borehole wall, giving a blurred picture of the geology. This RC rig provides a clean, depth-specific sample. However, conventional drills can often be faster and cheaper for non-sampling tasks like blast hole drilling. The choice hinges entirely on whether you need precise samples.

What’s the learning curve for beginners?

The learning curve is significant. An operator with general drilling experience will still need specific training on RC principles, air management, and this machine’s hydraulic controls. We recommend at least 1-2 weeks of supervised operation for a competent operator to become proficient and safe.

What accessories or additional items do I need?

You absolutely need a high-capacity air compressor (matching the rig’s CFM/PSI needs), a set of drill rods and bits, a sample cyclone/collection system, and likely a heavy-duty generator for remote power. These are not optional; they are essential to operate the rig and represent a major additional cost.

What warranty and customer support does it offer?

Warranty terms for equipment of this nature are typically customized. You must negotiate and get in writing the warranty period (often 6-12 months on major components), what is covered, and the process for technical support and parts replacement before finalizing the purchase.

Where can I buy it at the best price?

We recommend starting your inquiry at this authorized retailer for competitive pricing and authentic products. For large industrial purchases, direct negotiation with the supplier or manufacturer is common to get the best price based on your exact configuration and shipping needs.

Can it be used for geotechnical soil sampling?

While capable, it is overpowered for simple shallow soil sampling. It is designed for deeper, harder formations. For standard geotechnical investigations in soft soils, a smaller, dedicated sonic or auger rig is often more efficient and cost-effective.

How does its depth capacity compare to larger rigs?

This rig is designed for deep holes, but its exact capacity depends on the hammer type, rod size, and geology. It generally falls into the mid-range depth category, capable of several hundred meters. For ultra-deep exploration (500m+), larger, more powerful (and expensive) rigs are typically used.
