Great Value and tough
Don't go to your local hardware store or Harbor Freight for sanding disks. Buy them here and save money. They work well, they are durable and are a good value. I use them for not only rust removal but cleaning up steel both before and after welding. They also last just as long as other sanding disks I have purchased.

Good job for the cost.
Used to grind down 1/4" mild steel welded with 7018 welding rod and the actually did a very good job for the price. I would buy them again.

Real good deal get the 40 grit
I bought the 100 box of 40 grit. They work very good, super aggressive when new then like a 60 grit the rest of the way down. So just like any other flapper disk.

Well priced Flap disks
Order this pack for sure if you have a lot of fabrication to do--beats the price of flap disks from the welding supply by a lot
