Keep moving this in a circle or risk grinding unevenly. If you need to cut through some concrete. Sit in one place and this thing will go down! Seems to be wearing really well as well.

Excellent quality and durability for half the price

What a power grinding disc. Removes unwanted material fast and leaves a good working surface.

Fit good with my machines, work pretty good on terrazzo floor. Save much cost anyway.

I would like to leave the feedback and comment online, the grinding disc has long lasting and still going good. I purchased 12 units, seems enough for my next job in NY, I think

Grinds concrete blocks like a hot knife goingthrough butter…great tool at a good price!

The Discs fit my premaster machines well, so far they work perfectly.

I used it to clean up rough concrete on my house foundation walls and on my driveway. Lots of life left.

Amazing tool for DIY. I've used it with grinder at my Bathroom remodeling. It perfectly works on concrete.

Chews through concrete and stone 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.
