Simply wrap these around your 10" drum grinder to create a smooth and precise finish of your workpieces. Our pre-cut sandpaper measures 3.5 inches wide by 66 inches long so it can wrap perfectly around the WEN 65910 10 inch drum sander (sanding drum on unit measures in diameter of 5 1/2 inches and 10 1/4 inches in width). And although this pack-ready four pack was designed with the WEN in mind, the universal design allows compatibility with most 10" drum grinders on the market.
