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

best price for 2 works with angle grinder like a champ

Did a good job sanding my concrete countertops.

These grinder discs work as needed, but do not last long when used in hard building materials.

when i orderd the grinding wheels i forgot to measure the shaft on my makita grinder, so the holes in the grinder disc are a bit large. am trying to find a way to make the disc work with my grinder which has a shaft of .615 diameter and the holes in the grinding disc measure .80 diameter.

These grinding wheels wort great but they do wear down faster than the higher priced one. but they did the job at half the price.

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.

The description says 2. Why show 4?

I used four of these on an apox. 10 by 20ft. Sunroom to remove carpet glue from concrete floor. These will slightly eat into the concrete, so I plan on renting a concrete polisher to finish it before I start coating it with apoxy sealer. I strongly recommend a vacuum shroud to remove dust.

This removed the high side from a crack in my garage floor, about 6 feet long with a high side of 1/4-inch in less that 15 minutes.
