3M Roloc prato de suporte 50 mm ZR-AC com haste de 6 mm 7000077929

When grinding or surface conditioning with small die grinders, a rigid disc holder can cause vibration, uneven contact, and premature abrasive wear. This 3M Roloc backup pad solves that by providing a resilient, medium-density rubber face that supports the abrasive disc and conforms to the workpiece, improving finish quality and disc life.
