About Us

Sunny Superhard Tools is specialized in manufacturing premium diamond tools for construction and stone filed. Our diamond tools include stone cutting tools, diamond grinding tools, and diamond drilling tools.


“Quality is our culture” – we use high-quality artificial diamonds on our products, and some of the materials are imported from the famous brand of foreign countries. For example, our reinforced core drill bits are applied in high-quality diamond imported from “Element 6″ of Ireland. The steel wire of our diamond wire saw is imported from Bekaert of Italy and DIEPA of Germany.
