3M Xtract Net Disc 710W, 220+, 5 in, Die 500X, Pack of 50 Hook and Loop Sanding Discs, Virtually Dust-Free, Premium Option for Metal, Wood, Composites, Stock Removal, and Fine Finishing

Reduces sanding time and gives a better finish. It’s now the only sandpaper I use. Long lasting - durability offsets the price. Well worth the money.

Perform much better than what you can buy at the big box stores. I do a lot of sanding and these save time.

I've been cheaping out on sandpaper for years always favouring quantity over quality. I figured it didnt matter how long cheap discs lasted because if I could afford to replace them 5x as often anyway. These Cubitrons really do just peform better though. They remove material much quicker and more aggressively than the stated grit suggests and yet somehow they still finish as expected if not higher (e.g. The 80 grit cuts like a 40, but finishes like an 80+). This means you can sand with less stages AND each stage is significantly quicker, which saves a ton of time and effort. They last much longer than cheaper paper, although I'm not convinced that they last 6 - 8x longer (or whatever 3m claim), but they peform so significantly better, that the exact number doesnt really matter and I won't be going back to my old cheap paper ways.

So glad I upgraded to these. Sands way better than my last brand of sand paper. Smoother surface and less time sanding. Totally recommend!

Truly the best I've ever used, would give it five stars if it was available in all of the most popular grits. Come on 3M you can do it!
