Editor's Pick: When using an angle grinder to smooth weld seams or deburr metal parts, this flap disc removes material much faster than standard resin sanding discs. The zirconia abrasive is built to last, so one disc goes a long way without frequent changes. The Type 29 fiberglass backing keeps the grinding angle at 20 to 25 degrees—just hold the tool flat against the workpiece and push. Great for everyday metalworking and rust removal.
