3MStikit Disc 775L, 87430, Multi Pack, 5 in x NH, 240+, 320+, 400+ Coating Cut Cutting Angle Flute Purple

Based on functionality, durability, and cost; these are the best random orbital sanding disks you can buy!

These are for part of a sharpening system for tools that I am creating. I've used this brand of discs before and have not been disappointed. This batch has performed as before, so I can recommend.

Great

They do what they advertise.

3M has hit one out of the park with the cubitron series. Very effective and long lasting, the only reason not buy this is if you love sanding

Much thinner backing material than I expected. I used one pad one time and I'm not sure it will work anywhere near as well the second time. It seems to have lost much of its grit feel but we'll see. I saw it on a video, used as a sharpening system for tools. Not sure it will be cost effective or long lasting. Again we'll see

Great quality

I’m not sure if I ordered the incorrect item or if there is a design flaw. I put it on my orbital sander and that lasted for about 20 seconds before coming off. I wanted to see how well it worked so I folder on in half and wow. This paper cuts like no other. It doesn’t get dirty nearly is quickly as most paper. I have a ton of 3m paper I could of used but went with the folded disc instead because it truly is that much better. Btw. I’m sanding door fronts I just made.
