- Suitable for dry grinding of concrete and other masonry materials
- Double rim provides longer life and more aggressive material removal than a single-rim wheel
- High diamond concentration yields a fast cut rate

So far I have used this wheel to grind down a high spot in my driveway that always bugged me. I ground about 3/4″ of concrete away and it only took minutes. The wheel is fast and powerful. Of course, it creates clouds of dust, but that’s to be expected. I could have used it wet to avoid that, but since it was a windy day I didn’t bother and the clouds blew away fine.I am happy to have this tool to smooth out other rough concrete patches.The only con is that it leaves grind marks in the concrete. To smooth those out I also bought a cheaper, more disposable surface-grinding wheel (the sandy-grit kind, not diamond — see my “related product recommendation”)

I bought this grinding wheel for a small job which was to even out a concrete floor in preparation for new flooring. This works fast and made the job super easy. After grinding an area 6×4 foot square, the wheel is still basically new. I have more projects. A great buy. It saved me lots of money over hiring a pro.

This grinding wheel exceeded my expectations!! It does present some vibrations from the abrading process but that was expected.

Tool works as it should and no problems whatsoever. Just what i expected from dewalt. Very good product overall.

This is a great wheel for grinding up old thinset mortar ! I found it to be easy to control when taking thinset off of plywood, and it makes short work of it. I can’t speak for it’s durability yet, but after 200 square feet it seems like I’ve barely worn the paint off.

This wheel has a big appetite for concret. Will make short work of most any project. Lots of dust, wear a mask.

The Pro desk was a great help ordering it for me

Concrete hardness or softness determines blade wear and what the finished product will look like after grinding. This grinding wheel left marks in the concrete but this wheel is made for aggressive removal which i wanted. Other wheels can give you a smoother finish and might have to be used in conjunction with this one to get the desired finished look.

Had to smooth out rough plaster and concrete surfaces on our 22,000 gal swimming pool in order to re-plaster and paint. This 7 in. Double Row Diamond Grinding Wheel did it all in two weekends I can’t think of using anything else especially re-shaping & squaring up the steps it was great.
