It ground the hell out of a wavy concrete slab (caused by a bad batch). Took some work but it got the slab decently smooth.

This is a very aggressive tool and makes fast work on my project

Works well for smoothing, A bit harder to lower a flat area of concrete unless you put it slightly on edge to get a few grooves that can then be leveled out.

This is literally 1/4 the cost of competing products from any brick and mortar store. It worked great on a 10 sq foot are and has plenty of life left.

Very powerful diamond plugs,I used plug for most of my job, and the cost of DTS plug is much lower than what I paid locally. I will continue to buy next month.

The terrco stone arrived fast, grind well on my rough concrete

Excellent quality great for fast grinding, save time and cost.

My son tested the tool,perform very good so far.

I am amazed at how durable this thing is! I used it to rough grinding concrete. Lots of life left now.

Worth the money, I'm very satisfied.

Just as described. Aggressive grinding disc. Works well.

Perfect concrete cutter.

excellent quality great for fast cutting.

The cutting disc worked well on hard concrete.

It works great and fast. You better know what you are doing when you use it.

I've worked construction my whole life and I wish I found this tool years ago. It worked really quickly and did what I needed it to do.

Excellent for grinding cement. It seems to last for a very long time, I have done lots of grinding with it.
