I'm a flooring contractor and just got the Bosch 14 gallon self cleaning vacuum for grinding high spots in concrete and thinset under tile. Also got the 5 in Bosch surface grinder. Can't wait to use them.

Thank you for sharing your expertise on grinders! We can't make recommendations for which grinder's best for you, but we can recommend our DustBuddie for Hand Grinders for most users because it fits most major brands and models of hand grinders. We didn't mention it in this video, but we also sell a Wet+Dry Dustless Vac (D1603) and a HEPA Wet+Dry Dustless Vac (D1606), each of which with 130 CFM and semi-automatic or automatic filter cleaning. Let us know if you have any other questions!

Let us know how it goes! @@Michael_78

There are a few advantages to dry grinding. 1) Dry grinding does not obscure the surface that you're working on, making the surface easier to see and evaluate. 2) Wet grinding could cause harm to your equipment, specifically rust. 3) Last, but potentially most important is the fact that dry grinding (with a dust collection shroud) allows for immediate capture of removed contents. Dust can be captured at the point of origin, rather than swept up later, or vacuumed up separately after you've created slurry.

Sorry we missed that! Diamond cup wheels are preferred for grinding concrete because they're durable and leave a smooth finish. 4" cup wheels may be used for smaller, more detailed jobs. Where 5-6" cup wheels help cover large areas. If you're still uncertain on which cup wheel to use, then we'd love to hear what you're working on and how we can help with the project. Just give us a call at 800-568-3949 or email us at sales@dustlesstools.com.

Hopefully not physically hurt 😰 Glad you found the video helpful! If you have other content suggestions, we'd love to hear them. In the meantime, you can always give us a call (800-568-3949) or email (sales@dustlesstools.com). Good luck out there and Make it Dustless!

You don't necessarily need a minimum amperage to grind concrete. That being said, higher amperage usually correlates with higher grinding speed. Somewhere between 8-13 amps should work for most applications.

@@Dustless Thank you!

The ultimate RPM for grinding concrete depends on several factors such as the type of grinder, the hardness of the concrete, and the size of the grinder discs. Typically, for large grinders with diamond grinding discs used for heavy-duty concrete grinding, the optimal RPM can range from 250 to 1500 RPM. It's crucial to adjust the RPM based on the specific grinder model and the concrete's hardness to achieve the best results without damaging the surface.

You can choose to vacuum afterward, but airborne dust travels several feet at a time, making the area that you have to clean up large. It also settles in places that may be difficult to or impossible to vacuum up, including your lungs!😷

@@Dustless yes, after I try myself the dust is very disturbing, make you difficult to breath. I use mask since I don't have that vacuum gadget and than only I can finish my job 😊

It depends on how much moisture you add. If you add a small amount of water to the surface before you start, it shouldn't create a ton of slurry. If you are continuously adding water, you'll definitely get slurry. With a dust containment shroud such as the DustBuddie for Hand Grinders with a vacuum of 125 CFM+, moisture is not necessary to contain dust. Let us know if you have any other questions.

Yes, it sure will.

Be sure your vacuum has 25 CFM per inch of your grinding wheel.

Correct, we need a new demo slab! Shallow passes, steady hand, light pressure - key to smooth concrete! Choose quality diamond discs and fix cracks beforehand for even results.

Thank you for watching!
