What is the hardness of the tool?

The tool undergoes overall quenching and hardening treatment, achieving a hardness of HRC45-55, which ensures good red hardness and wear resistance.

Can this tool be used with electric drills?

It is strictly prohibited to use electric drills with three-edged blades. Ordinary bench drills may cause vibration, so high-precision equipment is recommended.

AI-Powered supplier vetting

SummaryThe supplier is identified as a limited company and trading company offering water pumps, solar pumps, submersible pumps, centrifugal pumps, and related equipment. It reports 10 years of manufacturing experience, four production lines, stated monthly capacity of 130,000 pieces, annual output of 1,600,000 water pumps, and pump testing procedures. ISO 9001 certification is reported. The supplier supports customization from samples and designs and provides OEM services for well-known brands, but does not provide 3D software design, ODM, or SDK services and reported no new products in the past year. Export activity is substantial, with 90% of total sales from exports and one year of exporting experience stated. After-sales and quality-management procedures exist, but written records were not provided. Customer references are limited to a general statement that the company has helped customers become market leaders.

Supplier typeThe supplier is described as a trading company and a limited company that independently conducts business under business licenses. Its scope includes pump and vacuum equipment, solar equipment, valves, hardware, and related products, indicating a broad equipment-trading and supply business rather than a narrowly specialized entity.

CertificationsThe supplier reports certification of its management system under ISO 9001. This is explicit evidence of holding a recognized quality-management certification.

R&D capabilityThe supplier is identified as a professional technical supplier and has R&D-related customization capability, but it reported no new products in the past year. It does not provide 3D software design, ODM, or SDK services, and its total R&D-engineer experience is listed as under five years, indicating limited demonstrated innovation breadth.

Production capacityThe supplier reports 10 years of pump and spare-parts manufacturing experience, four production lines, stated capacity of 130,000 pieces per month, annual output of 1,600,000 water pumps, and four testing stages for pumps, including motor-coil and leakage testing. These stated figures and processes provide explicit evidence of established production capacity.

Customization capabilityCustomization from samples and designs is explicitly offered. The supplier also provides OEM services for well-known brands, although it does not provide ODM services; therefore, its capability is demonstrated for customer-specified customization rather than supplier-led product development.
