These Patented See-Thru™ discs are what you need to work with the JOOLTOOL™. Combined with 3M abrasives, they allow you to sharpen, grind or polish with a crisp & clear view of the work piece. The discs have 2 faces: TOP: Molded fin structure that directs airflow onto the workpiece, keeping it cool. BOTTOM: Perfectly trued, flat surface onto which our 3M Ninja abrasives adhere. To install on the JOOLTOOL™ system, simply twist
onto the spindle. NO mounting hardware needed!
