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

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.

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.

Good Product

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.

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

El articulo resulto muy pequeño no como se veia en la foto.

Perfect size. Strong and durable. Can’t beat the price.
