10" Silicon Carbide 180G Sanding Disk

Finally got around to sanding some old ceramic tiles, and the waterproof adhesive held firm even when I ran water over the whole setup. The 180 grit leaves a smooth, even finish without clogging up too fast.

Used these to finish a knife blade after heat treating, and the 180 grit left a nice, even satin sheen. The self-adhesive backing held firm on my backup pad with no peeling at all.

The waterproof backing held up through a whole afternoon of wet sanding ceramic tile without peeling once. Silicon carbide really does chew through stone faster than any aluminum oxide disc I've used, and the 180 grit leaves a finish that needs almost no polishing after.
