Erduoduo 2 Pack 4 Inch Diamond Cup Grinding Wheel 12 Segs Heavy Duty Angle Grinder Wheels for Angle Grinder

Longevidad!

These are sad. You get what you pay for I guess. Each segment on the wheel had about 4 diamonds. The wore down quickly and didnt do much grinding. Spend more money and buy quality. Your job will be less frustrating.

The embedded diamonds are spars and straite the concrete as you grind it. If youre just rough grinding, and dont need them to last very long, these work well enough.

To fix an area of concrete floor.

I only received one grinding disc total. I did not get what I payed for.

Good item and good product

I used these grinding wheels to remove old paint from concrete steps.. they worked well. I ended up using both wheels in the package. The second one still has some life to it. The first wheel probably does too but after a while I noticed the paint was not coming off as easy as when I started. These are much less expensive than Home Depot so worth it.

Perfect

What I like about this 4” grinder disc is, it fits perfect on the 4 1/2 grinder. I used the disc to clean up old grout and tile adhesive. Cleans up excellent. I live in Puerto Rico and got it in a week.
