Frequently Asked Questions

To get a faster response, please fill in the aperture, rock hardness, equipment model, quantity, and country of delivery.
Operating parameters: hole diameter, rock formation, depth, and equipment model
Drawings, sample photos, current drill pipe specifications, thread type, and destination port also help us confirm the configuration and quotation faster.

Provide the hole diameter, rock formation, equipment model, and target operating conditions so compatibility can be confirmed.
Based on the borehole diameter, depth, rock formation, and equipment conditions, a matching drill string combination is recommended.
Products can be filtered by equipment connection, hole diameter range, rock formation, and drilling depth.

The company develops and manufactures DTH, water-well, reverse-circulation, rotary, and specialized drilling tools, providing reliable drilling solutions.

Key stages are controlled from raw-material traceability, heat treatment, welding or precision machining through thread accuracy, concentricity, and final visual inspection.
Quality control: material, heat treatment, welding, and machining accuracy
Verify the model, quantity, appearance, and key dimensions to confirm that the delivery requirements are met.

Material grade, joint material, heat treatment and acceptance values are controlled by the approved drawing and inspection plan for each model. Request the applicable material certificate and inspection record for the quoted configuration.

Send the hole diameter, rock formation, depth, equipment model, quantity, and destination country. Our engineers will assess the product series, dimensions, and delivery plan.
The team will recommend matching drill bits, drill rods, shanks, and related accessories.
Send us the borehole diameter, rock formation, equipment model, and project country, and we will assist in recommending a more suitable product combination.

The double-wall structure separates the inner and outer flow paths, so cuttings return rapidly through the inner tube. This helps reduce blockage, lower stuck-drilling risk, and keep samples cleaner by avoiding mixed layers.

It is suitable for RC sampling, mineral exploration, directional drilling, and deep hard-rock projects that require clean samples, corrosion resistance, and low magnetic interference. The non-magnetic version has very low magnetic permeability and is compatible with MWD/LWD directional measurement environments.

Verify the model, quantity, appearance, and key dimensions to confirm that the delivery requirements are met.
Depending on the product weight and transportation method, wooden crates, pallets, or reinforced packaging are used.
Photos are taken during the container loading process so that customers can remotely check the status of their goods.
Prepare invoices, packing lists, and shipping-related documents in accordance with order requirements.

Provides operational precautions, maintenance suggestions, and remote technical communication.
Upon receiving the on-site issue, the sales and technical teams collaborated to analyze it and provide solutions.
Send us your equipment model, drilling conditions, or procurement plan, and our engineers will provide more specific advice.

Prepare spare parts such as drill pipes, drill bits, and connectors for commonly used models.
Please provide the current tool model, connection type, working wear condition, quantity, and rig model so we can check compatibility and replenishment plans.

Supplier verification: certifications, patents, VR factory tour, and product details
Yes. We support batch orders, export packaging, container-loading records, and document preparation for import and project delivery.
Customers can combine product details, qualification information, VR factory viewing, loading photos, and trial orders to verify production and delivery capability.
