Mirka 9A-232-AP Abranet 5-Inch Mesh Grip Discs

Long lasting. Not scientific, but last about 2-3 good paper sandpaper.

These sanding disks are notably more expensive versus traditional sanding disks, but so far they seem to last at least twice as long, and because they are a mesh material, they do not hold onto contaminants, or other material that can scratch or swirl the surface that is being sanded. Overall they are working great.

I really like these mesh discs. Dust collection is excellent, they clog far less than paper discs, they seem to leave a smoother scratch pattern and last longer. The only drawback Ive found is that you need to use a pad protector inbetween the sanding pad and the disc, but thats relatively minor.

Great sanding disks but expensive

Been a woodworker, a long time, this is a good product, and you dont have to line up the holes.

Works well Good price Could last a little longer though

The mesh disks provide a superior finish. The Sungold product line of similar disks (see my other reviews) perform equally as well in my opinion. You will be pleased with either the Abranet or Sungold product. Buying by the box of 50 is the most cost effective.

These are best for larger flat surfaces. On narrow stock, the edge of the disk comes loose, sometimes creating a folded section at the out edge. Sometimes the disk would fly off, but that might have been due to condition of unlying pad. Hard to tell about longevity. Think Ill stick with Diablo

If it had not been for the money back guarantee it would have been nearly the biggest waste of money I ever saw! Sander ran for maybe 30 seconds before the disc flew off!! EVERY TIME EVERY DISC!

Unfortunately, the pads do not stay stuck to my Bosch ROS20VSC. Even after thoroughly cleaning backing pad.
