THE JOINT
CARBIDE STORY

Joint Carbide was born in 2007 in Zigong, China -- a city with deep roots in the tungsten carbide industry. What began as a focused R&D operation for carbide blanks has grown into a six-entity global group spanning raw material production, precision tool manufacturing, advanced surface engineering, and international export.

We are a professional manufacturer and high-tech enterprise integrating research, development, production, and sales of carbide burrs, carbide grit, carbide rod, carbide powder, wear parts, and recycled carbide scrap -- serving 20+ industries across the globe.

As China's first carbide burr manufacturer with a complete in-house material supply chain, we control every step: from wet grinding and pressing to sintering, fluting, testing, and shipping. This end-to-end ownership is what enables our unmatched quality consistency and competitive pricing.
