Enjoy exceptional life and impressive performance with this Metalite R228 coarse grit cloth PSA disc on your random orbital sander. Its premium aluminum oxide abrasive makes a good coarse grit surface that provides an excellent initial cut rate and consistent finish on both hard and soft woods, as well as most metal substrates. The durable X-weight cotton backing achieves good tear resistance and achieves a good balance between flexibility and resilience under the stress of normal use. This disc's pressure sensitive adhesive back allows quick and simple peel-and-stick disc changes while you work.
