About the Quick Change P.A.R.T. Disc
The Standard Abrasives Quick Change P.A.R.T. Disc Mandrel is designed specifically for use with our Standard Abrasives Quick Change P.A.R.T. Discs. These discs are used to remove surface contaminants, paint or primer at electrical grounding contact points. The disc’s center hole diameter self-aligns so it will only clean the workpiece hole and maintain the anodized layer surrounding it. Plus, they’re available in a range of grades and sizes for your specific application.
