JOY TECH (Xiamen Joy Technology Co., Ltd.) is a factory-direct diamond tools manufacturer founded in 2004, with over 20 years of experience designing, producing and exporting high-performance diamond tools for concrete, stone and construction applications. We offer a complete one-stop range across grinding, cutting, polishing and drilling, independently audited by SGS and Bureau Veritas and certified CE/RoHS, exporting to 50+ countries with custom OEM/ODM solutions.
Based in Xiamen, China, JOY TECH started manufacturing diamond tools in 2004. What began as a small production workshop has grown into a full-spectrum diamond tool manufacturer with a complete production line from raw material formulation to finished product. Over two decades, our tools have been used on commercial concrete floors, natural stone slabs, road projects and construction sites across North America, Europe, the Middle East, Southeast Asia and beyond. We build long-term partnerships through reliable supply, competitive pricing and responsive technical support.
As a one-stop supplier, JOY TECH covers every stage of concrete and stone processing — no need to source from multiple vendors:
This integrated portfolio means one quality standard, one order, one responsible supplier for your entire diamond tool procurement.
Our manufacturing process is fully integrated: diamond and metal powders are blended in-house, segments are hot-pressed or sintered under strict temperature control, and finished tools are balanced, inspected and packed before shipment. Key production steps include powder blending, cold pressing, hot pressing sintering, laser welding, brazing, sharpening and balancing. This vertical integration lets us control quality at every stage and keeps lead times short even for large orders.
JOY TECH is independently audited by two of the world's leading inspection bodies and certified for export compliance:
Every batch is subject to dimensional checks, segment bond hardness testing and runout/balance inspection, so the tools you receive perform consistently from the first box to the last.
Our in-house R&D team specializes in bond technology — tuning the metal or resin bond hardness to match specific materials, machine types and working conditions. We offer full OEM/ODM services: custom bond formulas, segment sizes and shapes, diameters, threads, branding, laser marking, packaging and private-label programs. Whether you need a standard catalog item or a tool engineered for a unique application, send us your specification and we will develop a sample within a short turnaround.
