💯 High-Quality Flap Discs 20 PCS 4.5 Inch - 40 Grit Grinding Discs, Assorted Sanding Grinding Wheels with Aluminum Oxide Abrasives - Grinder disc for Optimal Results Review

Really very bad quality, I wouldn't even recommend it for a hobby. There are better options for less money and much better ones for pennies more

I bought this Petal Disc 20PK 80grit for $21 but the discs are flimsy and you have to change them often. The $21 Neiko 10pk is thicker and lasts 3x longer than those 80 grit brown pads. If you're looking for a durable platter disc, then this 20PK won't fit. I use them to remove curb marks from rims/wheels so I'm sanding with a flower wheel all the time.

Less than $1 each is a very economical way to sand/sand my boat. At a retail store they sell for $5-6 a piece. You'll use a few of these and they don't go bad if you don't use them right away, so you can't go wrong at this price point. The quality is exactly the same as in the store. I haven't had any problems with any of them. Excellent purchase!

So they're not as good as $5 discs, but they cost less than a dollar each. But for the price, they work great. I've made good use of the two I've used so far and can't complain (cleaning an old trailer of repaints and modifications). I've seen comments about how quickly they wear out on welds and cuts and my first thought was the old adage "grinder and paint make you the welder you're not". They work well for what they are intended for. If you use the tool correctly, they seem to work fine.

I use a lot of Petal Discs so I decided to try these special Revain Discs. I was pleasantly surprised in almost every way. This is one of those rare occasions when you get more than you pay for. At $0.99 each they are absolutely no problem, tremendous value indeed. Benefits: The shaft bore is the right size and sits right in the middle of the disc. (It's a parody that this should even be a positive thing, but I've used too many discs with a sloppy mandrel interface and it was a real pita to…
