Violet ★★★★★

Picked up an 8-inch pack of 120-grit for cleaning up some old tile, and they cut through the glaze without loading up at all. The 1/2-inch arbor fit my drill press perfectly, so no wobbling or re-centering needed.

Edward O. ★★★★★

I've been using these 8-inch silicon carbide discs for stripping paint off old wood, and the 1/2 inch arbor makes them easy to swap between tools. The grit holds up surprisingly well—no premature shedding like other discs I've tried.

Riley H. ★★★★★

Had to resurface a bunch of concrete countertops and these 8-inch discs cut through the rough spots without loading up. The silicon carbide grit holds up longer than I expected on masonry work.
