3M Cubitron Xtract sandpaper


Recommended Posts

i did purchase some of this a while back after reading about it on another site, have to say, i'm kinda on fence, everyone touted it cut faster, more for less cost, ect .

i use the red from HD store and some klingspor, for boards and most sanding, have to say, i was not overly impressed, and will say, when i discovered there was no absolute revelation in sanding with the stuff, gravitated back to my original, have a bit of it and will use, have to use a mat to put on hook and loop, OB's, its not bad, can't say for sure its the new ""cats meow"" so to speak.

yeah, i think this is the reason i went for it, but actual for me, perhaps i was using it wrong or who knows, but was not at the least impressed with its success, i have a bit of it and will in future probably try again, and at least use up what i have, but a while back i invested in a festool, choked on price, but have to say its flat out sands, and gets the work done. 

no matter what the modern paper is way beyond what we had decades ago.

I read that the original product had more "grit" on it than the later production runs. I can't say if that is true as I haven't used either the old or new.

This is true.  The mk-1 was solid grit, and the mk-2 is about 50%.  The mk-1 was so bullet proof that the backing evaporated before the grit wore out; I still use the first sheet I ever got, on a hand sanding block.  Cubitron won't work on a stationary disk sander, ROS only.  [Actually, you can use it on a stationary, but you have to really baby it or it just augers a groove in the grit].  The word to look for:  "ceramic".  The ceramic grit seems to make the difference.

I'm using some right now. I was able to buy a sampling of grits from somewhere (Taylor Tools, I think)...seems like I got 5 discs each of 5 grits in a box. Early on, I found much of the dust stuck in the hook pad on my sander, That pad was as old as the sander (20+ years) so i replaced it and the dust doesn't seem to get caught in the new one; but that's with only limited use so far. I got pretty excited about it after I watched that video above when someone linked it here some months back. I just haven't been in the shop enough this summer to give them a real workout.

My sanding experience over the years has boiled down to the following-----buy quality brand name paper---use each sheet-disc a short time---toss and use a new piece ----using all the grits successful seems not usually necessary[to me]  150 grit is often recommended for many stains and or finishes----long story short over sanding has minimum advantage-----works for me.

Good to see you posting again Marv. Hope all is well up North.
