this is soo helpful! I am new to this and am surprised how little help there is out there just to explain the proper way to install the grinder cup wheel. The manual that came with my Bauer grinder was no help when it comes to surface grinding wheels. Thanks for this!

Do not use a dust mask when grinding! Use a proper respirator with at least P100 filters. At the VERY least, use an N95 mask.

Almost had me😂. I thought you were using a 1773Ak bosch. If you’re doing a lot of grinding it will burn up a normal grinder and he dust though out a regular vacuum, making them pretty worthless. Lots of companies make grinders and self cleaning vacuums for this intended purpose. Have had very good success with Bosch.

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!

For larger jobs, you may want to use a concrete scarifier or planer. Very expensive to rent though.
@tileslay6543Күн бұрын
Going to battle with concrete isn’t for the faint of heart. As a flooring contractor I’ve had to learn concrete for floor prep. Yes scarifiers work great, same with large edco dual head grinders. The best way is to test the concrete hardness in multiple locations and marry the diamonds to the hardness. Shot blasters work well depending on texture looking for. I have a lot of machines, really depends on the job to how I load. The Bosch grinder can out preform the dual head in some applications. The main thing is dust extraction. The Bosch and festool vacuums work well coming in at 200cfms. But an S 36 eliminator paired with a little grinder works even better. That sits around 330cfms. Concrete is complicated and there is no one tool fits all.

What about wet grinding? Any advantages to dry grinding?
@Dustless5 ай бұрын
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.
@jeffbauman54479 ай бұрын
Can I damp the surface prior to also minimize the dust or does it turn into a sludgy mess?
@Dustless9 ай бұрын
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.

Id say the first step is picking the right grinder. Which is what im trying to find out. What is the minimum amperage?
@Dustless5 ай бұрын
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.

What’s the optimal RPM for grinding concrete?
@Dustless2 ай бұрын
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.

Great that you mentioned it was important to pick the correct grinding wheel, and then not giving any actually useful details.
@Dustless Жыл бұрын
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.
