Use the foam interface pad for sanding delicate surfaces such as profiles and contours with the RO 125 or ETS 125 5-inch sander. The secret to a great finish lies in the use of the right pad and abrasive for the application at hand. A highly-resilient, heat-resistant MPE foam is utilized in all our pads for consistent finishing results, uniform wearing, and extended pad life. Because sanding pads will eventually fatigue and require replacement, it is advisable to keep a fresh pad at hand to avoid a break in work. Includes 1 sanding pad.
