Review on 🪓 Assorted Grit Sanding Discs, 5 inch (125mm), 8 Holes, 70 Pcs, Includes 40 80 120 240 320 600 800 Grit Sandpaper by Ryan Sandell

You get a lot of parts for a good price but in my set two grit did little or nothing. The 40 and 80 grit, which one would expect to pick up a piece of wood well, did very little and I used them for a good half hour without ripping the piece off. I finally gave up and upgraded to 120 and immediately saw the difference. All grains 120 and above were much better and performed as expected. I spent almost an hour working 40 and 80 thinking something was wrong with my grinder or technique when the sandpaper was the problem. If these two grains worked I'd give them 5 stars - each held up well on my Bosh grinder, were the perfect size and seemed pretty solid.
