How does the T-shaped design benefit cutting?

The gaps between segments boost chip removal efficiency and accelerate heat dissipation, preventing overheating and segment shedding.

What is the manufacturing process used?

The blade is manufactured using mature hot pressing technology to sinter high-grade industrial diamond and high-strength steel.

AI-Powered supplier vetting

SummaryQUANZHOU JINGSTAR CO., LTD. is a China-based limited company in Fujian, established in 2018, with eight employees, three production lines, and a stated 100 m² manufacturing plant. It supplies diamond tools, including cutting disks, segments, saw blades, grinding disks, and wire saws, and reports exports to multiple global regions. The supplier states that it has production, design, quality-control, sales-support, and after-sales teams, although the evidence does not quantify service performance or quality outcomes. It reports one year of R&D engineer experience and six to ten quality-control staff. Claimed order lead times are within 15 working days in both peak and off-peak periods. The supplier identifies “Others” for management-system certification, without naming a specific certification. Trade records show several 2025 transactions involving products such as polishing discs, copper strips, cutting bits, and brazing coils with a Pakistan buyer, but the limited buyer and transaction coverage does not...

Supplier typeThe supplier is identified as a combined business and a limited company operating in China, with Tools & Hardware as its commercial trade category and diamond tools as its stated product focus. The available information supports classification as a product manufacturer/exporter, but does not clarify the exact meaning of the “Combined” designation.

After-Sales capabilityThe supplier explicitly states that its sales teams provide sales support and after-sale service. However, no evidence describes service procedures, response times, warranty terms, or documented service performance.

Production capacityThe supplier reports three production lines, a 100 m² manufacturing plant, and a product range covering diamond cutting, grinding, and sawing tools. It also states lead times within 15 working days in both peak and off-peak seasons, but the limited facility size and absence of verified output-quality data prevent a stronger conclusion about capacity.

Client casesTrade records document transactions in 2025 with PAKISTAN STONE COMPANY involving brazing coils, polishing discs, copper strips, and cutting bits. These records confirm at least one identifiable buyer relationship, but they do not demonstrate a broad, diversified, or referenceable customer portfolio.
