Review on 🛠️ Sansheng 4-Piece Concrete Grinding Wheel Set: 4-inch Diamond Cup Wheels for Angle Grinder - Perfect for Grinding Concrete & Granite by Luis Mercado

I ordered these two packs to remove a thin set from a concrete base after removing 20 year old tile totaling about 500 square feet. I used an inexpensive angle grinder and these discs to remove the thin set left over from the impact drill/4 chisel I used to take the tile and remove the heaviest bits of the fine set. I have never used this type of disc. they worked great before, i wore out one of the discs but the other was only needed for the last 100 SF or so, it has plenty to use. They worked well for me and were a lot cheaper than the big alternatives, which started at $40 apiece and grew from there. Happy with this purchase.
