- Sali 20 Pack Zirconia Flap Disc 40 Grit 4.5" x 7/8-Inch Sanding Disc Bevel Type #29 Premium and Industrial Grade Angle Grinder Grinding Wheel High Performance Edge Grinding

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.

I have purchased these discs before and will continue to do so in the future. They hold up well.

These flap discs last a decent amount of time and cut really well.

These work good / last fairly long comparatively speaking

Great Quality and Great Value!!!

They do the job.

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.

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

Impressionnant, ça passe au travers du fer comme dans du beurre.

Work great but wear out quicker then the expensive ones, that’s ok tho because they are much cheaper and get more use for your money with these
