The 3M™ Flap Disc 563D G60 is an alumina zirconia abrasive flap disc constructed on a Y-weight, strong, durable cloth backing. Resin bonded for heat, this 3M™ Flap Disc is ideal for medium-pressure applications on flat and contoured surfaces, especially in light deburring or weld leveling to prep for paint in mild steel. It’s also great for stainless steel fabrication where finish and gouge resistance are important.
