3 Pieces 4 Inch Concrete Stone Ceramic Turbo Diamond Grinding Cup Wheel,12 Segs Heavy Duty Angle Grinder Wheels for Angle Grinder (Yellow)

Product description states “2 pieces” and photo in written description shows TWO grinding disc’s. I only received one (1) disc. So, either the description is wrong or I was only shipped one of the two items. Mistakes can happen, it would be nice to receive both disc’s or be refunded a fair amount for one item. I have not used the grinding disc yet because I wanted to address the issue first.

Im a home owner and had a small project that I needed the grinding wheel for. It performed very well for my purpose.

So I had a lot of mortar left on the floor under the Durock after ripping up the tile floor. I attached the wheel to my DeWalt grinder (I used the included washer) and started sweeping it side to side like I was wiping the floor. It ground off the mortar like butter. Within 2 minutes I had cleared about 12 square feet. In the pictures I am showing about a one square foot of mortar. The second pictures shows the thickness, about 1/4. In fact there was part of a screw remaining down in there. It whipped that area clean to the wood within 15 seconds, including the screw (sparks). It requires zero pressure, it just eats mortar and any nails or screws get ground down too. I will say that goggles and mask are a must. The amount of dust in the room made it impossible to see what I was doing every couple of minutes. By the time I was done, 15 minutes of actual grinding on a 10x10, my hair was coated in a thick powder and eyes burning. Basically I would stop every couple of minutes due to not being able to see through the dust. After about 30 minutes it settles and I went back to it, stopping periodically due to thick dust. The first wheel looked like it had been hardly used after doing this room. It makes the wood look almost brand new like a sandpaper machine. I dont know what it would do to a concrete floor if you needed to grind an area, but Im sure it would be worth trying. Well worth the money and you get two wheels!

this does not screw on (does not have a nut welded onto it) so you have to secure it using the nut for Cut off saw discs. Otherwise it appears to be as good as the Dewalt product. I gave it five stars because based on the value/price it’s a good buy.

This product was exactly as described and worked well

I bought this item for a one time used. It sanded the uneven pavement down to my liking. Used less than 5 minutes without grinder shroud, got very dusty during used.

Been using this on fieldstone for a month. Holds up great. Just as good as the more expensive versions. Great value.

I used one of the 2 that I purchased on a small area but didn’t last as long as I thought it would but did smooth concrete nicely.

Worked great

Good product
