> 3 dayBought this two pack to remove tile morter from underlayment. Used a 4 1/2 inch angle grinder fitted with a dust shield and shop vac. Removed 200 square feet of morter using one wheel! Wheel still has some life left. Very satisfied.

10-06-2025After 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.
