Let me tell you, this dust shroud turned my concrete grinding nightmare into a surprisingly clean operation. I was prepping my garage floor for a new aluminum threshold, and that one stubborn high spot was driving me nuts. My Harbor Freight angle grinder (yes, the cheap one) paired perfectly with this shroud using the included adapters - though fair warning, that 'universal' hose adapter is anything but universal.

The magic happened when I actually started grinding. Not a single speck of dust escaped! I literally laughed out loud when I finished and saw my still-clean work area. The soft brushes create this perfect seal while letting the tool glide smoothly. Sure, you're flying blind under there (can't see the disc at all), but for controlled surface work like mine, it's worth the trade-off.

Three things to know: 1) The included wrench didn't fit mine - had to use my grinder's tool. 2) You'll likely need to MacGyver your vacuum hose connection (I sacrificed an old Shop-Vac hose). 3) That 'fits 90% of grinders' claim? Maybe 90% of grinders after modification. But once it's on? Absolute dust-collecting beast.

For $30-ish bucks, if you need serious dust control for concrete work and don't mind some fitting adjustments, this shroud delivers where it counts. My lungs and clean garage thank me.
