Diamond spot discs with adhesive backing are made of premium diamonds bonded with metal powder, making them highly effective for grinding and polishing hard materials. These discs have an open-dot design that allows for efficient stock removal and a more aggressive cut while providing an excellent surface finish. They are commonly used for ceramics, stones and other very hard materials. The use of water as a coolant during grinding helps remove debris and chips, preventing overloading and increasing the efficiency and longevity of the discs. These diamond spot discs outperform traditional silicon carbide discs and alternative diamond compound systems, offering superior performance and resilience.
