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

I used it to grind down about 150 sf of my concrete porch that had uneven and damaged concrete, prior to resurfacing it. This disk made the job so easy. Make sure to wear a mask and eye protection because you’ll make a lot of dust and things will be flying all over. Beat part is, after all this grinding I still have about 90% life left on the disk!!

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

I used these grinders to remove paint from a huge concrete surface. More than 50 yrs. and 4-5 layers of paint and mildew. Saved myself a lot of money. The picture posted is one small section completed. With patience the end result is phenomenal.

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.
