sansheng 4 Pieces Concrete Grinding Wheel 4 inch,Diamond Cup Wheel Angle Grinder Wheels Grinding of Concrete, Granite

Fast shipment. Item works well. Thank you

The center ring was off when i received it

I had a concrete slab that was a old house and it still has 1970s glue and tile. These to it all right off! Did a 12x10 area and didn’t even wear half of a blade down!

I have a slab of concrete on my sidewalk where one side has sunk and raised the other side a significant amount (~ 3/4 to 1 in). This make quick work of the problem. I was able to flatten out the concrete to where there was no longer a tripping hazard. The grinding cup is still in great condition. Theres a couple of raised areas in my basement from old support beams I may tackle next.

Works great! No complaints. If you have a one time job just buy it.

Cant beat it for this price

This concrete grinder was awesome. Before I burned out a cheap harbor freight grinder this thing was grinding the concrete away with no issues. When I had finished this grinder attachment looked like it had hardly broken a sweet and was ready for more.

I couldnt believe how fast and easy this removed the concrete! Be careful, because it DOES the job. VERY happy the way it worked.

Good quality

Fantastic on aged concrete, so-so on premixed thinset (white garbage). I was able to grind out 100 of floor cracks and lumps in no time. Not as effective against softer materials like white thinset but thats to be expected. Definitely use a dust shroud, my smaller project produced a few pounds of very nasty dust. Excellent value!
