"Cant say how long a wire brush spinning at 12,500 rpm is expected to last. This brush did last about 45min to an hour constant use. It was used to remove masonry paint or similar on concrete steps. It was not quick at removing the paint, just slow and steady. The paint was many levels thick easily 3 or more layers
I think its OK for a budget brand buy a few and return the unused if its a large job"
"Although I agree with the other comments on here, the item is fair for the price considering it is a budget brand. It didn't last long, and I was only rubbing car panels down. I found the Draper Expert 52637 to be excellent!!"
"Designed for angle grinders but the vibration of this means two hands are essential. Didn't last more than a couple of hours light use. Fell apart firing out small pieces of wire that stick in your clothes or any bare skin."
