I purchased this to grind my 750sqft garage in prep for epoxy/polyurea floor coating. This is a large space and I am a bit crazy for doing this by hand however this goes quicker than I imagined. I am about 5 hours into it and halfway done. This really scuffs the floor very well and quickly. Watch out as it can get away from you and cut into the floor however it is pretty easy to control. I would suggest if you have anything more than a 1 car garage an actual floor grinder would be best. I would just rather spend my time and save money as their are no close rental companies
Edit: This is taking much longer than i thought i think i will have had about 20 hrs into grinding the floor by the time im done for a 750sqft space. I dont think id di this again but also hasnt been terrible either. I have done all of this with one "blade" and have plenty to finish up.
Some of the concrete grinds well and ither bits take some time. I believe this to be the concrete rather than the "blade"

Purchased to knock down concrete sidewalk corners for easier snow removal using an old 7A, 4-1/2" angle grinder which has a 5/8" threaded output shaft and 7/8" mounting hardware. A true 4-1/2" grinding cup might not clear the guard so I opted for the safe (and less expensive) option.
The cup fits the inside (unthreaded) mount. The base of the friction surface is about level with the guard. The output shaft does not extend past the base of the friction surface.
The one minor issue is the outside threaded mount contacts the inside of the cup about 1/3 of the way from the intended clamping surface. Not sure yet if this is a problem or not but it seems to work OK. With that said, at the RPMs this sucker will be spinning at, I'd prefer it to clamp as intended. Maybe I'll go to the hardware store and buy a 5/8" nut and flat washer.
The abrasive material appears to be adequately fastened to the formed metal backing cup. I'd hate to think of the carnage if a chunk of it broke free during use and clipped me in the nuts.
At this price point I don't expect them to last forever and haven't tested them yet. Based on other reviews I'll assume they are just good enough to knock down a few high concrete coners.
