### ⭐⭐⭐⭐⭐ Affordable and just plain work.

### ⭐⭐⭐⭐⭐ Sanding disc

Excellent item quick delivery and easy to use great price.

### ⭐⭐⭐⭐⭐ I'm a convert to flap discs!
*by G***N on 12 April 2023*

I've always used a wire wheel to clean up my welds. I still use the wire wheel, sometimes, but for the most part one of my grinders is dedicated to flap disc use (another grinder has a thin cutting wheel on it, and the other usually has a thicker grinding disc on it). The flap discs definitely don't last and last, but man do they work nicely. No grabbing the work and making the grinder jump in your hand. They take off metal reasonably quickly but at an easily controllable rate. Perfect for cleanup. In case you're an idiot like me - don't use the flap disc on just-welded metal. It's really hot and will probably wear the disc much more rapidly. Go clean up the previous weld first, then this one.
