Let me start by saying this: if you've ever used an angle grinder indoors, you know the horror of dust clouds. The Dastool DT1706 promises to tame that chaos, and after testing it on tile, stucco, and even a stubborn countertop cut, here's the real deal.

The Good: When it works, it WORKS. Hooked to a shop vac, this thing sucked up 85-95% of dust in my tests—no more post-cut snow globes in my workspace. The transparent window is genius; I could actually see my cutting line without squinting through debris. Bonus points for the toolless installation (though more on that later) and the depth adjustment screw that made precision cuts a breeze.

The Ugly Truth: That "universal fit" claim? More like "universal frustration." My Makita needed Dremel modifications (RIP warranty), and those soft mounting screws stripped faster than a budget Phillips headdriver. Twice, I had to pause projects for hardware store runs—pack your patience and M4 metric screws.

Pro Tips From the Trenches: 1) Tape over side holes (massive dust reduction hack). 2) Face vacuum elbow forward—weird but catches more debris. 3) Dedicate one grinder to this attachment; swapping mid-job made me question life choices.

Final Verdict: For $30-ish, it's a flawed lifesaver for occasional indoor cuts. Just wear your mask anyway—this isn't magic—and maybe buy backup screws before starting. Weekend warriors will love it; daily pros might rage-quit during installation.
