3M Xtract Net Disc 310W, 120+, 3 in, Die 300V, Pack of 50 Hook and Loop Sanding Discs, Virtually Dust-Free, Value Option for Metal, Wood, Composites, Stock Removal, and Fine Finishing

These really are better than the cheap red disks. They sand quicker and leave a smooth finish with no swirl marks

These disks are the bees knees. The dust collection is superb, they stay sharp the longest I’ve been able to find. The sanding quality they leave behind is second to none. I mean they’re actually worth the money cause they last so much longer. They stick to the pad real strong, so never slippage. The blue color is kinda cool but most importantly makes sanding a breeze and finishes come out so spot on I would be hard pressed to try anything else. Mostly using on woodworking projects as a profession

Can’t without this. Mesh is the way to go.

The sandpaper is great, no issue there, all the reviews about dust collection and effectiveness are true. But... I was using a 6" Bosch ROS and was humming along just fine, quite impressed with the performance of this sanding disc. When I went to change the disc, though, for some reason the second sanding disc wouldn't stick to the backing pad of the sander. Turned out all the hooks (of the hook and loop system, the loops being on your sanding disc) of the backing pad were gone! After reading up online I found other people have had the same problem. The mesh on these is loose enough that, at least with some sanders, the hooks poke through to the business end of the disc and get worn off. Backing pad's for 6" sanders aren't cheap... I now have a new backing pad and a "pad saver" coming. Hopefully the combination will last a bit longer. At least I'll just ruin a pad saver next time, instead of an expensive pad. So! Bottom line, great performance, great discs, but use a pad saver so you don't ruin your sander like I did.

I had to try these discs after watching a comprehensive review and test of a bunch of different manufacturer(s) sand paper. To be brutally honest I thought there was no way that the 3M paper was going to be a value considering the cost of the material in comparison to what I've always used from the big box stores. In short: this stuff far exceeded my hopes and blew me away with how well it performed. Even my wife commented when she walked out into the shop. Where are all the used discs? Usually she comes out and sees the remains of the demolished paper on the shop floor, and there wasn't any today! I am a believer and future sandpaper will be the 3M Cubitron II Series!
