Customer Reviews (4.8 / 5 · 5 reviews)

Victoria ★★★★★

The adhesive backing stayed firm through a full afternoon on my angle grinder, and the zirconia grit chewed through some seriously rusty steel without shredding. Cut through hard metal like butter.

Sophia ★★★★★

I was impressed with how well these zirconia discs held up on a heavy grinding job, the adhesive backing stayed put even after swapping them several times. The blue/green color is a nice visual cue for knowing which grit is loaded on the sander.

John ★★★★★

The heavy Y-weight cloth backing really holds up under pressure, I've been using one disc for hours on some stubborn metal without it tearing. It sticks firmly to the backing pad and leaves a consistent finish.
