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

I had to make some spacers to get them on a very old makita side grinder and remove the safety guard but they worked great. Safety shield and heavy gloves an absolute must!

So much better then the $35 each ones I’ve purchased in the past. Great value.

Did my garage with 1 but purchased 3

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.

Perfect

These do the job but I have no idea how long they will last. One thing I noted immediately was any paint they come in contact with will clog the cutting surface and must be scrapped off to continue.

Compared to the expensive disks these are a great value for cheap

Good Product

Longevidad!

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.
