Review for 4.5" 115mm - Zirconia Flap Discs

These sanding discs work just as good as some of the expensive wheels out there. I highly recommend this product in 40 grit for stock removal… I have not tried any other grits, as I prefer 40 grit as an all around sanding, grinding disc. My experience with 60 and 80 grit is that if you use it to grind with, it wears out and just burns up.
