## Customer Reviews

### ⭐⭐⭐⭐⭐ Still on the first disc after heavy use, great quality!
*by C***S on June 11, 2025*

I was expecting to go through several on my metal restoration projects, but I’m still on the first one — and it’s holding up great. These flap discs chew through rust, scale, and old coatings with no problem. Minimal wear, solid construction, and great value for the price (especially compared to northern tool or even harbor freight). I’ve used it on thick steel and old components, and it hasn’t slowed down.

### ⭐⭐⭐⭐⭐ Good so far great price
*by D***S on June 11, 2025*

Seem to work really well for more blades I only used it once so far going to buy the contraption that you put your grinder onto and set the degree of grinding you want for the mower blades

### ⭐⭐⭐⭐⭐ Grinder sanding wheel
*by H***  on June 25, 2025*

Working great
