A highly flexible abrasive wheel that runs cool and is suitable for cleaning up welds and discoloration, light grinding, and paint and rust removal is available from Rex-Cut Products Inc.
Sigma Screen™ depressed-center Type 27 wheels feature a blend of zirconia-ceramic abrasive grains bonded to a flexible mesh. They run cool and provide chatter-free performance, the company states.
The wheels do not clog and are available in coarse, medium, fine, and very fine grits. Measuring 4-1/2 in. by 7/8 in., multiple wheels can be stacked onto a grinder for use on metals and composites.
