Who It's For

The dust port is ideal for hobbyists and small shop contractors using a DeWalt DWS779 or DWS780 12-in sliding miter saw who want a cleaner workspace without upgrading to a cabinet dust collector. Anyone who currently relies on the saws stock dust system or a minimal hood will see improved vacuum efficiency and less floor cleanup.
