4 1/2" 8-Loch H&L schwarze Zirkonia Gator USA Scheiben 50er Körnung

I've been using these on my angle grinder for some heavy metal deburring, and the 50 grit cuts through rust and scale much faster than my old ceramic discs. The hook-and-loop backing holds tight even under pressure, and the 8-hole dust collection really keeps the air cleaner.

Finally got these to replace some worn-out discs for heavy paint removal on a steel boat hull, and the 50-grit zirconia cuts fast without loading up. The hook-and-loop backing holds firm even on a right-angle grinder, and the eight-hole pattern keeps the dust down enough to see what I'm doing.

I needed something aggressive for stripping paint off an old metal cabinet, and these 50 grit discs with the hook-and-loop backing really grabbed hold without clogging up. The zirconia material held up longer than the standard aluminum oxide ones I've used before.
