Norton BlueFire R887D Cloth Quick-Change Discs have an improved base adhesion which reduces grain shedding and minimizes loading on soft metals such as aluminum, brass and bronze, as well as stainless and carbon steels. Moderate grinding, beveling, blending and finishing are key applications for these new discs., plus offer a supersized grinding aid for cooler cuts and minimized loading, which results in longer life on stainless steel and other harder-to-grind materials. In addition to metal fabrication and welding, R887 Cloth Quick-Change Discs are ideal for heavy grinding in challenging applications found in industries such as aerospace, wind turbines and oil/ gas.
