Diamond spot discs with adhesive backing are premium diamonds bonded with resinoid, making them highly effective for grinding and polishing hard materials. The open-dot design allows for efficient stock removal while providing an excellent surface finish. 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.
