This makes short work of concrete. We used it to remove the concrete lippage and I can't imagine it being any easier than with these grinding discs. After large area grinding, the tools looked like they have hardly any wear. The thickness of the grinding discs are much enough to grind off an entire warehouse.

Great price and good tool.

The special design of beveled edge segments help to cover the gap among the floors so easy, Nice Grinding Discs I ever used.

The quality is excellent! Fast delivery! I am very happy

These are very nice diamond dics. I use them in my concrete floor restoration business

Order came quickly. All good quality, thank you.

I was amazed how well this product worked and for the price. It is perfect. It ground down the material quickly.

Well received for the good packing and tools works good on the terrazzo.

These discs grind down some uneven areas with ease.I was really impressed with just how well it did, and it still has many, many more hours of use left in it. I will definitely be using it for future work as well!

A alsome device can't wait to try it. Really fast shipping

Performed beyond expectations for the price.

just what I needed, works great.

used this to grind down some concrete for better door clearance.Very pleasantly surprised at how this performed.

Excellent. Was able to grind down a concrete countertop to smooth finish in no time at all.

Fast delivery, I ordered 4 days ago, and I received the tools yesterday, GREAT。
