Looks nice, diamonds are much thicker than my current Scan tool. Fast delivery as promised. I will test them next week with my new Scanmasin machine.

Works great grinds concrete with no problem. Use a dust collection system or a steady stream of plain water to keep dust down. Trust me.

I am amazed at how durable this thing is! I used it to clean up rough concrete on my house foundation walls and on my driveway. Lots of life left.

grinds solid concrete well...looks like it will wear quickly

This cup worked great on an uneven bathroom floor.
