I bought the 4.5 " Diamabrush blade to remove Some Old Cutback [asbestos] vinyl flooring. I bought it with some misgivings, but after I used it, all my misgivings vanished. I, at first used my Milwaukee hand grinder, was way too fast, blade danced around. Fortunately I had a Milwaukee, variable speed polisher, a Big one. At a slower speed this blade did it's job efficiently and thoroughly. Hint, in the video it shows the guy laying the brush on the surface, I found it more effective to bite off the vinyl/cutback. Of course the old wood flooring will need some sanding. Also, It actually did not break any blades on some nails.
Have some of that nasty flooring, this puppy will do the trick, it generates a ton of dust. Looked like I was smoking a pack of camels in my hall way.
Have at Cowboys.

Rated 5.0 out of 5.0 by Kewstow works awesome.
I used this tool to remove 50 year old black, sticky mastic from my floor. I wanted to acid stain my floors, a contractor told me I would never be able to remove all of the mastic from the floor to acid stain them. Well he was wrong, the floors look like brand new. I used the "Dust Buddy" shroud and a 6 HP shop vac and no dust!!

It's tough to spend $150.0 on an abrasive tool and shroud for just 20 sqft of concrete floor, but I am really happy with the result. The tool removed the black mastic without too much effort, and not much dust.
I used a wet sponge to keep the floor wet and blades cool, and had the shroud connected to my shop vac. Light semi circular motion with minimal pressure on the grinder, and with a few passes I was into clean concrete.

Rated 4.0 out of 5.0 by BilltheEngineer Works better than anything else I tried for removing mastic and paint off of concrete
This does what it is says. It removes whatever is on the surface of concrete without really removing to much concrete. It barely removes any concrete and does so in a slow enough manner that you don't have to worry about gouging the concrete. It is it soft concrete like bring it will eat into it quickly. This does work better than a wire wheel, carbide grinding or polishing stones and abrasive wheels. Abrasive wheels work well but cut into the concrete easily as well.
A few helpful pointers:
-You don't need to force to the tool to work, more pressure just wears the blades out faster
-Use a dust shroud on your angle grinder and connect it to a vacuum, otherwise you are in for a dusty clean up. I think you can use it wet but you still will end up with a mess to clean up.
-Wear a respirator not just a dust mask and hearing protection
-A variable speed grinder or a slower speed grinder works just as well and the blades last longer. A typical 11000 rpm angle grinder works but it wears out the blades quicker
-Buy a set or two of extra blades
Mine came with a little wobble to it but it works fine still. When brand new not all the blades contacted the concrete but in a few minutes of use it was. I got about 75 square feet of use out of a set of blades.
If your concrete is really rough than a grinding/polishing of it may be a better option.

One pass and mastic is removed, leaving a perfect finish for your flooring. I used it on a small bathroom floor. If you're doing a large area, like an entire room, rent the larger version, along with a floor maintainer, from a Home Depot with a tool rental center. Remember: a LOT of concrete dust is gonna be generated by this process; wear safety glasses & use a breather.

The dimabrush wheel did a great job at removal and roughing up the concrete surface. My only problem is that the diamond pads are wearing out much quicker than expected coverage area.

Bought this product and only lasted a few hours. We removed the tile and was using it to take of the adhesive off the concrete floor. Didn't want to rent one, because we weren't sure when we could start and finished. This was planned on being a evening project. Very expensive item to last a few hours.
One of the scrappers broke off.
