Riley ★★★★★ Oct 22, 2026

The 12-mic finish on these is perfect for my final polishing pass—leaves a clean, even surface without gouging. The plain-back design holds up well without peeling. Pack of 50 should last a while.

Edward ★★★★★ Oct 21, 2026

I’ve been using these 9” discs for final surface prep on metal parts, and the 12 micron grit gives a consistent finish without loading up too fast. The pack of 50 should last me a good while.

Violet ★★★★★ Oct 20, 2026

The 12 micron grit on these lapping discs is just right for my precision finishing work. I picked up the 10-pack and each disc holds up well without tearing along the edge. They cut consistently from the first use to the last.
