Overlapping layers extend durability for prolonged use in industrial operations. Poly-cotton backing resists edge tearing or fraying under high pressure. Phenolic resin plate provides cushion effect for optimal blending and dampens vibration, reducing operator fatigue and tool wear. Grinding aid keeps the disc running cool on stainless and heat-sensitive alloys.
