The 3M Disc Pad 4-1/4in Coarse Grit provides faster and more aggressive cutting than SC and PD discs in heavy-duty deburring and finishing projects. Its strong hook and loop attachment ensures a secure fit, preventing it from damaging the base material. The open-web construction of the disc prevents loading and runs cool, guaranteeing a consistent finish. The 3M Hookit attachment system allows for an easy and quick disc change-out for multi-step finishing.
