Terms & Conditions

All drilling equipment specifications, bit diameters, air consumption figures, and metallurgical descriptions published on this website are provided for general engineering guidance. Because rock formations and rig conditions vary across project sites, final tool specifications, thread profiles, and tolerances are confirmed in writing on your formal quotation or order confirmation.

Quotations issued via WhatsApp, email, or RFQ forms are valid for the duration stated in the formal quotation document. Prices, lead times, and minimum order quantities for custom-machined tools (including specialized PDC bits, DTH hammers, and drill rods) are subject to raw material and manufacturing schedule confirmation.

Performance and wear life of drilling tools depend heavily on ground geology, air pressure, flushing velocity, rotational speed, and feed force. Customers are encouraged to share accurate formation and rig parameters with our engineering desk so we can match the optimal carbide grade and tool geometry.
