Dry grinding discs are specifically designed for dry grinding and polishing applications, capable of working effectively without the use of water. They are commonly used for grinding, sanding, and polishing substrates like concrete, corundum, and inorganic terrazzo base plates. These discs are made through special processes and formulas to ensure they don't overheat during dry operation, reducing dust generation. Compared to wet grinding discs, dry discs do not require water cooling, conserving water resources and minimizing the risk of water pollution.
