> 3 dayAttempted to use to remove thinset from concrete. Hardly any diamonds on the cutting wheel, was barely removing product, job would have taken forever. Not worth the hassle. ended up buying a Norton wheel for $45, cut right through the thinset no problem.

> 3 dayI had to make some spacers to get them on a very old makita side grinder and remove the safety guard but they worked great. Safety shield and heavy gloves an absolute must!

> 3 dayAfter modifying the grinder vacuum head and the right size spacers I started grinding on my rough basement wall and it worked excellent. Took down high spots, nubs and concrete blobs on the wall pretty fast and easy. I didnt have to put much pressure at all, it just ground it down nice and smooth. Im happy with them, got the two pack at a good price and they work great.

> 3 dayI purchased these grinding cups to remove about 100 sq ft of tile mortar from my concrete basement floor. I use these cups on a 4 1/2 inch black and decker corded angle grinder with a cheap dust shroud. The quality for the value on these is great. Each cup took off approximately 50 ft.² of mortar.
