Diamond discs with adhesive backing are made of premium diamonds embedded in a metal-plated bond, making them highly effective for grinding and polishing hard materials. The heavy-duty polyester backing provides structural support, durability and stability during grinding and polishing steps. These discs allow for efficient stock removal and a more aggressive cut while providing an excellent surface finish.  They are typically used for hard materials, excluding high-carbon or hardened steels. 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 discs outperform traditional silicon carbide discs and alternative diamond compound systems, offering superior performance and resilience.
