Moore’s snap on discs are one of my absolute favorite tools for the @foredomelectric flexshaft. They can be snapped on with the abrasive facing up or down making them super versatile. They are my go-to for sprue removal and work great when I have a flat surface. Like any other new mandrel always use on a test piece to get a feel for what it does before going straight to a piece you’ve worked hard on. These can easily put deep scratches in your work if you linger too long in one area #metalsmithsociety #sanding #polishing #jewelrymaking #foredomtools #foredomflexshaft #flexshafttools #sandingdiscs #instasmithy #metalsmithing
