Review on DEWALT DW4930 4 Inch 8 Inch 11 020 Inch: Ultimate Cutting and Grinding Tool with Multiple Sizes by Tommy Hilmy

Works great, I used this in combination with a Dewalt 11A angle grinder (DWE402K) to remove adhesive from a concrete wall and it worked phenomenally for that. I've also used it to remove rust from a few things and it's worked pretty well, but I prefer brass over steel for rust removal.
