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

Arrived timely and a cool disc

I form rocks for tumbling this works so well it is unbelievable

Great for the price, also work very well. Talking of around the house, not professional to judge..

I cant recommend this for a large project, but its good enough for a small project, like taking the edge off of uneven concrete walkway. It takes some repeated back-and-forth, but it does the job.

Bought this to grind a raised crack in a sidewalk...worked BETTER than I hoped Took off over an inch of concrete about 3 ft wide in minutes with a $30.grinder ( also bought on Amazon)

Excellent product. I removed the paint from my concrete patio in short (but extremely dusty) order with little or no wear to the blades.

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!

I used this to remove thinset tile mortar and it did the job but only lasted for about 90 - 100 square feet. After that the teeth were worn down almost to nothing. If you need to do a large area I would suggest going with something a little more durable/harder material teeth or get a bunch of these knowing you are going to burn through them quickly.

Great Value Acceptable Quality at SALE Price. Buy with 100% Confidence AMAZON Prime has your Back. Thank You AMAZON Prime

I received my order today and when I saw the discs, they are extremely thin. Im going to try them out, however I dont expect them to perform as good as they say. Ill follow up afterwards.
