Inspection at Every Critical Stage
Quality control is integrated into our manufacturing process. Key dimensions, connections, welding, cutting structures, surface finish and order specifications are checked before drilling tools are approved for packing and shipment.
Critical dimensions such as bit diameter, body geometry and key machining dimensions are checked against product specifications.
Threads and connections are checked for size, profile and compatibility with the required drilling equipment.
Welded areas, cutter seats and assembled components are visually checked for consistency and manufacturing quality.
Blade layout, cutter quantity, cutter position and product structure are checked against the confirmed configuration.
Finished products are checked for surface condition, painting, anti-corrosion treatment and overall appearance.
Before packing, the product is verified against the order requirements, including size, connection, quantity and customized specifications.
Raw materials and components are checked before entering production.
Key dimensions and manufacturing conditions are checked during machining and assembly.
Product structure, cutter layout, connection and customized specifications are reviewed.
Painting, surface condition and anti-corrosion treatment are checked after finishing.
Finished products are inspected before packing.
Quantity, product specifications and order information are confirmed before shipment.
Each order is checked according to the confirmed product specifications and customer requirements before shipment.
Customized drilling tools require more than standard inspection.
For special sizes, threads, cutter layouts or structures, the finished product is checked against the confirmed drawing, sample or technical requirement before shipment.
For customized orders, we can provide product photos, dimension confirmation and packing information before shipment when required.
