3M Xtract Cubitron II Hookit Clean Sanding Film Disc 775L, 320+, 3 in, Pack of 50 Hook and Loop Sanding Discs for Paint Preparation and Removal, General Sanding, Refining, Blending, and Featheredge

I run a wood shop and build projects daily for my online store, so I’ve gone through a lot of sandpaper over the years. Normally, with standard paperback sanding discs (180 grit), I’d be swapping them out every project—or every other project if I was lucky. But the 3M Cubitron II discs are on another level. I put one on almost a month ago, and after dozens upon dozens of projects, I’m still using the same disc. And here’s the crazy part—it still sands beautifully. It hasn’t clogged up, glazed over, or dulled out like every other brand I’ve tried. I don’t know what 3M puts in this stuff, but it feels almost alien-like in how long it lasts. Sure, it costs a little more upfront, but the value is undeniable. Instead of burning through a stack of regular discs, one Cubitron keeps going—and going. Bottom line: This is the future of sandpaper. It’s going to make traditional paperback discs obsolete. If you’re on the fence, take it from me: it will save you money, time, and frustration in the long run.

Works great smoothing epoxy coffee table in preparation for final epoxy coat. Cuts well and the holes provide just the right amount of clean out

After years of flirting with those bargain bin sandpapers that promise quantity over quality, I finally decided to go big and grab the 3M sandpaper. I have to say, the difference is almost embarrassing I genuinely had no idea what I was missing out on until I started using these for my auto body sanding projects. The consistency is just next level. With the no-name brands, the grit would vanish faster than my motivation on a Monday morning, turning what should have been a 300 grit into a glorified napkin after just a few swipes. 3M’s sandpaper actually holds its grit the entire time you’re using it, which means I’m not constantly reaching for a fresh sheet after every panel. The build quality is noticeably superior; the paper is sturdy, and you can really lean into it without worrying that it’s going to shred or smooth itself into oblivion. For auto body work, that’s a game changer. I ended up with a far better finish, and no exaggeration the end result is way more professional. One thing I noticed right away was the lack of annoying dust clouds. With other brands, I’d be sanding for a minute and then choking on a fog of debris. But the 3M stuff keeps dust to a minimum, making the whole process cleaner and saving me time on cleanup. The finish you get is actually the grit on the package, not some mystery number that fades after two minutes. That consistency really builds trust. After seeing how well these perform, I totally get why all the pro shops stock only 3M. There’s literally no tradeoff just a better experience, every single time. I’m officially a convert, and my days of buying bulk “mystery” sandpaper are over. If you care about getting a perfect finish (and maybe saving your lungs from dust clouds), just get the 3M.

By far the longest lasting and most effective sanding discs I have ever used. They can really take a beating. I hope they continue to offer these at such a reasonable price

I needed some medium grade sanding discs. I have purchased inexpensive disks in the past thinking they were better deals. The 3M Cubitron disks are actually a much better deal. They last much longer. By that, I mean up to 10x longer. The project I was working on would have taken at least 6-8 cheap disks versus just one 3M (and it was still good). Not only do these last much longer they cut much faster. Everything I purchased under the 3M label has always been great and this is no exception.

These discs cut fast and clean, and the film backing holds up way longer than paper. The hole pattern helps a lot with dust collection, and grit options are spot-on. Great value for serious sanding.

Cuts much faster and gets through twice as many boards without dulling. HOWEVER, the hookit portion gives out WAY before the disc loses any sanding efficiency and they literally will fall off of your sander. Great if you're trying to rush through a small batch but not really worth $80/50 pack when you can spend $40/100 on a Mirka set that'll get you through at least the same amount.

I usually use 80-grit on the redwood I'm working with to start. I can use the Cubitron 120 grit, and it takes 1/3 the time. ABSOLUTE FANTASTIC PRODUCT.
