I used one flattening a very rough concrete wall about 20ft x 5ft
it cut well and lasted well.
I used it in a heavy duty 7" angle grinder.
Review by Goomer on March 27th, 2012
I have worn out two of these turbo cup wheels over the years. One was an expensive name brand and the latest one of these HF. In my opinion, they were equal in quality, the only real difference is in the price. These are hard on a 4 1/2" angle grinder, by the way. Regardless of the brand. I found that they work fine in a 7" and won't overheat and kill the grinder.
