The Dust mizer is designed to be used for dustless cutting in confined areas.  Best used for flooring cuts or very limited wall cuts.  The size and weight of the grinder make it physically difficult to cut walls for any length of time.

With this setup, you cut on an upcut to maximize the dust collection.  The better vacuum you have, the more dustless it will be.  It does a great job, but nothing is 100% dustless.  For shallow cuts or scoring, use a smaller diameter blade or better yet a Mizer 005 assembly with a 4 or 4.5" diameter blade.
