This disc is amazing how much concrete it will grind off.

I Used this to taper garage concrete front lip down to be level with driveway concrete, and to do same to several sidewalk segment ends that were no longer level. Did great job, and pretty quick.

I had to remove high spots off my garage floor where it settled and came to a peak in the middle which made it impossible to get a good seal between the garage door and the floor.This tool worked really well with my angle grinder and enabled me to fix a long standing problem in an afternoon.

Creates a smoother finish than I expected.

I couldn't believe how good this worked for the price. Put it on a 4 angle grinder, kept the concrete wet and it worked perfectly.

Fast shipping, and nice packing. Seems good quality.

Chews through concrete rapidly. I needed it to smooth down the raised edge when a slab was lifted by roots. Very little wear after 2 hours of constant running.

I bought this to grind concrete floor of my home. The concrete is 12 years old and very hard. I would certainly recommend it.

I have 3 discs 4-inch discs on the machine, work good so far.

Awesome quality,grind fast

Fit well on my grinder, work pretty good

Works well! Aggressive but controllable and left a smooth surface.
