7" PCD Grinding Wheel for Epoxy, Glue, Mastic and Paint, 6 PCD Segments, 5/8"-11 Threaded Arbor

My exterior basement wall had been previously coated with liquid nails and some laminate. I had remover the laminate many years ago and painted over everything with UGL block paint. The paint was peeling, so I decided it was time to repaint everything. At first I started with a wire wheel cup on a 4 1/2" grinder. That removed the loose paint fine but was slow getting through the glue. Then I tried a stronger bead wire wheel. That was better and I cleaned up a portion of the wall with it.I looked for a diamond wheel and found this one with good reviews. I went to test it on the wall to see how long it would take. I ended up finishing the rest of the wall in about 15 min.The wheel is pretty aggressive and does mark up the wall a bit, but the glue was gone in no time. If you dont want crescent shaped gouges, then I would get something less aggressive. The wheel doesn't show any signs of wear so far. I would purchase another if I ever need one, but this will last through my project.

Used cut through thick rubber like waterproof coating that was failing and peeling off around foundation walls

Three times faster than a brand new 40 grit disc alone.I run this across really quickly, so I don't dig into the concrete, then follow up with the 40 grit disc to smooth it out. Harder concrete is more resistant to unwanted abrasion from this wheel, but test it somewhere safe first.If you've got a big job this is tool for you. They make angle grinder style paint removers with wheels similar to this and adjustable depth settings. If you need to avoid harming the surface, that's the tool for you.

Fantastic wheel for removing adhesives from concrete. It will dig into soft concrete so keep the grinder flat and moving. I expect this to have a long life.

I don't usually write reviews but had to on this one. I needed to remove 50 years of epoxy/polyurethane coatings off of our upper deck, about 4 coats. This thing took care of it in two days what would have taken a two weeks or more with a liquid stripper. Worth every penny and still looks brand new.

Don’t really know a lot about them, I just Know my husband had me purchase a bunch of different ones for a job he was doing and this is the only one he had me order again. His crew said the others were crap.

This wheel has worked great so far for about 600sqft of Epoxy Coating Removal, still plenty of life left in wheel. Would remove coating with one pass. The PCD cutting segments are not as well attached as I would like but that could be why the price is lower, but other than that one issue which does not affect performance only possible longevity I can't complain wheel works great on any surface including concrete removal thinset paint off carpet glue mastic you name it PCD will remove it.

This has worked well for removing coatings and glue on concrete
