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 model, quantity, appearance, and key dimensions before shipment.

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 pipes, shanks, and related accessories.
Send hole diameter, formation, equipment model, and project country so we can help recommend a 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.

Factory inspection checks model, quantity, appearance, and key dimensions.
Wooden crates, pallets, or reinforced packaging are used depending on product weight and transportation method.
Photos are kept during container loading so clients can remotely confirm cargo status.
Invoices, packing lists, and shipping-related documents are prepared according to order requirements.

Provide operating precautions, maintenance suggestions, and remote technical communication.
After receiving onsite issues, the sales and technical teams work together to analyze them and provide handling suggestions.
