Uking Diamond is a Zhengzhou, Henan-based superhard material supplier providing PCD cutting tools, PCBN inserts, PDC drill cutters, PCD wire drawing dies, and diamond thermal management substrates to industrial manufacturers worldwide. Henan province accounts for over 80% of China’s synthetic diamond and CBN output — Uking Diamond’s position within this supply base gives customers direct access to the full range of grades, geometries, and custom specifications produced in this manufacturing ecosystem.
We work with procurement engineers, tooling managers, and R&D teams across automotive, aerospace, oil & gas, semiconductor packaging, wire drawing, mining, and precision machining industries. Our role is to identify the right product configuration for each application — whether that is a standard ISO PCD insert for aluminum alloy turning, a custom-diameter wire drawing die for fine copper production, or a CVD diamond heat spreader for a GaN power module.
What we supply:
- PCD and PCBN cutting inserts(turning, milling, boring) & PCD cutting tool blanks
- PDC cuttersfor oil & gas and mining drill bits
- PCD wire drawing dies(0.04 mm–33.0 mm bore)
- Diamond heat spreaders(CVD polycrystalline and single-crystal)
- Diamond-copper and diamond-aluminumthermal composite substrates
- Resin and vitrified bonddiamond grinding wheels
Why customers source through Uking Diamond?
Consolidating superhard material requirements through a single technically-informed supplier reduces vendor management overhead and shortens lead times compared to direct negotiation with multiple specialized factories. We verify product specifications, manage quality documentation, and provide application-level support — ensuring the correct product reaches the production line rather than the nearest available equivalent.
Send us your application details — workpiece material, required geometry or ISO model, target quantity, and current tooling limitation — and we will provide a matched product recommendation with pricing within one business day.
