DustlessTechnologies -DustBuddie Universal Dust Shroud for 7-1/4 Inch Worm Drive, Circular Saw Dust Collection, Circular Saw Dust Collector, D4000

Used this with circular saw to cut 3cm granite in a kitchen. Using a clamped down guide, it took about 4 passes to cleanly cut thru. Covered the area with plastic overhead to the floor, vented the vacuum hose out a window with an extension, barely had any dust escape into the kitchen area. It's a great tool, but needs to be reversible for different directions of cuts, different sides the saw blades are on (L vs. R). I retro fitted it and it worked well.

This is the best product on the market for a worm drive saw that I know of. As Siding contractors we own and use several of these constantly. Most of our work is with fiber-cement products, on commercial and multi- family projects that have strict safety regulations. These meet all of the new OSHA silica dust rules. This greatly reduces dust pollution in the cut station. I highly recommend this product.

Oh yeah, this baby definitely cuts down on the dust!!! We were remodeling a hotel and putting up solid surrounds. We were able to cut in the rooms without choking on the dust. I thought about a special saw, but this enables me to keep using my current DEWALT!!!

Works good. Picks up dust and rolls well on broom finished concrete.

I really Like the easy glide and usage. But cannot use a guide bar once unit is installed because it sits too high and the strap goes right across the guide bar screw

I bought to use cutting pavers. Several problems became readily apparent.1. Depth of cut: the foot plate is so thick that I can’t cut a paver in one pass. This means I have to flip them over and try to match the cuts. That’s hard to get just right. No big deal so far, when I can hide those edges, but not good for the rest of my patio. With a 7” concrete blade the depth of cut measures 1.25 inches, which with a wood blade might just barely be enough to cut a 2 x 4.2. The whole foot seems to lose 90 degrees, and be slightly off.3. The vacuum hose attaches horizontally, flush with the bottom. This means that the hose can snag on the edge of the paver, and detach. Wouldn’t be an issue if you were cutting lines in concrete slab4. Dust collection is decent. If you go really slow. If you go at any pace, dust escapes. I tried setting up a second vacuum, but that would need something like a built up cutting box.Overall, a purchase I regret for this project. If all you were doing was cutting lines in concrete, where depth was no matter, this might work great.

Works great.

They need to rethink the design for the price. Rubber boot that catches the dust comes off, doesn’t fit smaller saws, comes loose and the straps fail over time, makes it hard to see your accuracy: better off holding a hose in front
