I’m SOLD on this stuff by 3M. Mostly all the work I do requires a GOOD sandpaper, and I have found they are not all created equal. Many just wear quickly, or pack up with debris.

Cubitron!!!

My problem is I have plenty of Cubitron discs for my sanders.

I’m about to run out of the common 9×11 sheets of Cubitron and I simply can’t find it anywhere????

I’m wondering if 3M has decided to only sell it in discs? I also see it by the roll but at times I require a wider section so SHEETS work best for me…

Maybe 3M thinks Cubitron should only be used on electric sanders??

Strange, the Home Depots near me sell the sheets and the small velcro pads that go on their sanding pad.
Though the name seems to have changed to “Pro Grade Precision”, if you look at the pics it mentions Cubitron II

I agree that it’s great stuff. I haven’t done any kind of testing so my evidence is anecdotal, but they are aggressive and last lots longer than the run-of-the-mill stuff I’ve used on my 5” ros. Love the series of small holes for sucking up the dust. Much easier than lining up the regular holes. No more looking for the cheapest stuff to save a buck. I believe that you get what you pay for with Cubitron.

I never used this stuff and never heard of it. I searched and took a look. It has a series of small holes in a sort of spiral. I was wondering. on a standard 5-8 hole sandpaper, if you just slap a regular disk on without lining up the holes the hooks on the sanding disk will wear off and not work any longer in that spot. I’ve had some mirka disks. Gread sanding disks but they’re sort of a mesh weave. They have no specific holes for air induction. I found that it wore off the hooks on my sander after awhile. They have a pad that you can get that sits between the paper and sander but I had mixed results with it sticking so stopped using them. I’m wondering if this disk with all it’s holes will have the same results?

I am going to try it as it looks interesting. Found this picture of regular paper versus cubitron.

I have some cubitron but didn’t know it was special. Now I know that I should perhaps:
1. Buy more
2. Use the little I have left sparingly

It exists, at least 120 and 220. Finding it may be the issue. I would suggest online as the best marketplace to replace really long drives.

Same. Not a terrible price either.

I have some ordered and will try. I have some concern that it will be too aggressive. After reading more about it, seems like it works very well for grinding metal. I will post a review after trying it.

I would probably be using it for lapping if it came with a PSA backing in the form of a roll at least 4” wide. All the rolls of the stuff that I can find appear to be for hook-and-loop setup. I’ve also read that the backing is somewhat non-stick.

13 Minutes of video, comparison done following a relative scientific model approach… some controls, some data reviewed etc…
I watched this, and it sold me on the Cubitron…. Have NOT looked back since using it…
13 minutes BUT well worth the watch..

I worked for an industrial abrasives distributor an we sold 3M products. 3M Cubitron was their high end product sold more to the metal working industry. It was / is a high priced product that was well worth the cost. If you were willing to compare cost to finish. More for the high end machining shop that dealt with alloys and stainless steel products than your basic weld shop. It definitely was cost effective in the right application.
For woodworking I don’t know. Some abrasives tend to load (clog) when used in softer materials. My opinion 3M Cubitron was made for metal working. You’re over paying for using it on wood.

I’ve been buying/using Cubitron discs for about a year and a half now in a commercial woodwork shop setting. Before the Cubitron discs, we were using both Klingspore and Sia products. Both Aluminum Oxide.
There isn’t any comparison between them…none. Cubitron is in a league of it’s own.
The Cubitron discs are about 150% higher in cost than those two, but at the end of the day they’re a big money saver. They last at minimum 4 to 5x longer, so thats an easy win right there. Another consideration is that they also cut considerably faster with a more consistent cut pattern. I’ve never done a stop watch comparison, but labor savings would probably (safely)be in the 25% range. Thats HUGE.
I’ve since tried both Sia and Norton ceramic discs as well and neither one stood up to the Cubitron’s.
To the Abranet diehards…tried those as well….keep em.
After 30+ years in the woodworking industry, I have very few ‘holy shit’ moments anymore when sales reps come pushing their various products. Cubitron was a holy shit moment.

Thanks Tony S. I never called on any wood working shops so your feedback is very interesting. In fact I don’t recall the 3M reps ever mentioning wood working (say a cabinet shop) as a possible user of Cubitron.

If you used mesh type discs without an interface – you’ve ruined your sander’s pad.

Cubitron will not have such issues – it’s only mesh top abrasives like abranet, sandnet, granatnet, ect…. If you use mesh type abrasives you MUST USE AN INTERFACE PAD PROTECTOR !
