I hadn’t used this type of sanding drum before and was worried about the glue coming loose as it heats up during sanding but that hasn’t been an issue at all. The grits all work well and the arbors fit my cordless angle grinder perfectly. If you need to do a fine finish these are not the best choice but for removing a ton of material fast these are great. I like that fact that as they wear down they keep working far longer than those tiny rotary tool sanding drum do. And the price is decent too.
