Since stumbling across the Roloc quick change system a few years back, these discs have become one of my go to products for stripping and grinding. They are such a fast and convenient way to work with different abrasive grits when doing metalwork and autobody repair. This package of discs is a nice a quality as any that I have ordered previously, the abrasive is sharp, the discs wear well and last a long time. It's nice to be able to order a substantial quantity of discs at such a reasonable price point.

100 discs at $16, I was not expecting these to be that good. But, I am surprised at the quality actually. They are not quite 3M or some of the other top tier sanding discs but, darn good for the price I must say. If you need to remove a bit of rust and/or paint for weld prep, painting or just general smoothing of just about any metal, wood or plastic, these are more than satisfactory. The abrasive seems to hold up well without loading up with paint and the cloth material is strong and resists tearing. The threaded back/mount stays put as it should. The threaded backing fits my generic threaded holder perfectly. You will get plenty of work done with these discs for cheap.
