These grinding cup wheels I used can grind concrete floors efficiently. I will buy again from this supplier.

They are robust, durable, and consistently deliver excellent results. The company's service was impeccable, offering prompt responses and addressing all my queries. Highly satisfied!

I was honestly shocked at the performance of this cup wheel. It last long enough to smooth the part of my garage floor I needed to do. I worked with it continually for over an hour and the wheel showed nearly no wear at all.

Good quality diamond grind wheel. Cuts great and still lots of life left after a long time grinding.

Everything came as expected. Very good quality of the diamonds, The whole process was really smooth.

I want to say it is great grinding wheels, better quality than what I bought locally, and the grit 16 cut so fast. I love it.

I want to say it is a great wheel, cutting my floor very fast, it is a powerful wheel.

Fast delivery, I use it with my hand machine to grind the concrete. Cut very fast.

It worked with my hand grinder, it cut realy fast. Good Wheel.

I wasn’t sure at first, but this thing performed super. Wore the first one out and then bought another. I would buy it again. I Had to grab the threshold to my garage doors

I have surface ground about 20 square feet of painted concrete block with this wheel so far and it barely shows signs of use. It removes material quickly and leaves an smooth surface as long as you keep it moving. If you stop it will dig in fast. It creates a massive amount of dust so a full face respirator is highly recommended.

After grinding approx 20sqm it still works fine. When wetgrinding a lot of dust gets bogged in between and needs no be cleaned every 1sqm or so. But good deal for the price.

A little expensive, but worth it.

Appears solid and performs OK with a grinder.Rough grinds concrete and masonry OK just not sure how long it will last. But for the price it's great.

This diamond grinding wheel is almost indestructible! I've used it to remove old mortar and tile adhesive from over 2000 sq ft of reinforced concrete floors and it still has at least 50% of the blade thickness left. Very well balanced with factory balancing holes drilled on the back of the plate.

Was prepping to put down tile in our laundry room. Pick up in time for the weekend project and it tore through the concrete ridges. The floor came out even for a nice tile job.

Aggressive grindinging wheel. Works well.

I am using this wheel to grind down exposed aggregate finish concrete on my patio that is pitted from wear and 25 years of age and I really like the aggregate finish after grinding it smooth and a lot cheaper than new concrete.

I don a lot of work with no damage high recommandet this item Thank You

Awsome blade great fast removal
