Let me start by saying this dust shroud is a GAME CHANGER for concrete grinding. I used it with my DeWalt angle grinder to prep my garage floor, and the difference in dust control was night-and-day. No more coughing fits or dusty footprints trailing through the house!
The GOOD:
- The soft brush seal works like magic - I literally saw zero dust escape during flush grinding against walls
- Surprisingly universal fit (with some tinkering) - I had to remove a trigger guard on my DeWalt, but it locked on securely afterward
- Contains sparks beautifully - no more worrying about setting fire to nearby lumber piles
- Makes cleanup 90% easier - my shop vac caught nearly everything
The NOT-SO-GOOD:
- That "universal" vacuum adapter? Yeah, it's basically useless. I ended up MacGyvering a solution with an old hose and duct tape
- Visibility is terrible - you're basically grinding blind under there (I marked my target spot with chalk first)
- The included wrench didn't fit anything on my setup - keep your metric tools handy
PRO TIP: If you're using a name-brand grinder, be prepared for some minor modifications. That said, once it's on, this thing performs like a champ. For $30, it saved me hours of cleanup and probably years off my lungs' lifespan.
Final verdict? If you do occasional concrete work and don't mind some DIY adjustments, this shroud delivers where it counts - keeping the dust contained. Just don't expect perfect out-of-box compatibility with every grinder.
