Lately, I've been sanding a few interior doors that were painted with some SW water based paint about 20 years ago. This is only a temporary fix because I'll be replacing the doors in a couple of years. So I'm not trying to strip the paint from the door but just level it out and scuff it up for a new coat of paint.

I've been using 180 Cubitron II in a ETSC 125 set at speed #6 with the standard dust bag. The results have been excellent, the surface is really smooth with minimal gumming up on the Cubitron paper. 3M claims that the Cubitron discs run cooler than normal and the results I got are the proof of that statement.

Here's a view of the disc after 20 minutes of sanding with the bag on. Very minimal build-up and the Cubitron grains are still sharp to the touch.




However, I decided to empty the dust bag and this is what I found.




After seeing this, I decided to install a new disc, hook the sander up to the MIDI and sand for another 20 minutes. Here are the new results.






Difficult to see from these photos but you can feel the differences on the paper between using just the bag and instead using a vacuum. The Cubitron grains also feel sharper when using the vacuum.

So you think the paper is limiting air flow which is causing the dust to buildup inside the tool?

Did you run the same test with Festool paper?

there is no question hat the paper/film discs restrict air flow. the holes between the festool and 3m do not line up well.

Not really, it's just that the small internal blower on the ETS 125 can't compete with an external vacuum on sticky paint residue. The only difference between photo 2 & photo 4 is the addition of the MIDI and the MIDI was only set on #3.

I've sanded a lot of bare teak with just the bag attached and never noticed the restriction when I emptied the bag.

I've more pieces to sand and I'll swap out some Granat for the Cubitron and see what happens. This may not be an issue with the ETS 150 because the pad on the 150 is much more open.

There's also no question that, everything being equal, a sander performs better with the use of dust extraction (set to proper suction) than not.

The newer 3M Extract might be a better choice. It has a much more open pattern that should let it breath better on the Festool sanders.

Is there an intermediary pad needed to use Cubitron paper on a Festool sander?

I would say that this is one of the problems that you run into with after-market consumables that are intended to fit everything. It turns into a compromise, which is "good enough" for most of the things it fits, but not ideal for any of them.

I hear what you're saying but there is supposed to be a corporate "synergestic" & professional business relationship between 3M and Festool...one would hope that some of these seemingly niggling issues would have been resolved. I bring this up because the sanding pads for the Festool 150 mm sanders look to be a better fit with the 3M product than the 125 mm sander pads.

A "pad saver" needs to be used with Cubitron net discs but not with Cubitron film discs. The film disc is manufactured from 3 mil polyester film so it's incredibly tough...tougher than any paper or cloth backing product.

What is interesting is the 125 mm pad saver from Festool vs 3M. Here's Festool #203344 first & then 3M #20444.






Here's an interesting comparison between 3M net and Mirka net. Towards the bottom of the page there is a series of videos. Click on the "Side-by-Side Comparison"

Another good comparison of various brands of paper (19 in all I believe).

I'm just loving the Cubitron paper so much when sanding these painted doors that I decided to order some for the 6" ETS EC sander. I ordered it from a local place, R. S. Hughes, that stocks all the sizes and all the grits. The nice thing is they can be purchased in single pieces only if a person just wants to take a few for a test drive.

Thanks for posting this Bob...watched it and it's interesting & surprising at the same time. Surprised that Abranet was rated as low as it is.  Here's the overall findings for you 10-minute managers out there.

Saw it watched the whole thing and tried the 3m Extract, while there was some valuable info.  There is a difference between sanding test panels robotically and real world sanding.  I can without a doubt say that the film discs outperform the Extract in "real world" sanding except for dust collection IMO. Its unfortunate that the film disc holes dont align better with Festool hole pattern.  Either way hands down the cubitron discs are the best on the market if you need durability get the film if you are more concerned with dust control get the extract.

Correct me if I'm wrong, but I don't believe they used protection pads in that test which is almost a requirement with the net discs and with Xtract. In the link Cheese shared, 3M recommends protection pads in the PDFs. If so, the test is somewhat misleading from a price standpoint.

"There is a difference between sanding test panels robotically and real world sanding."

Agree, in the 'lab' and in the field are two different environments.

And wasn't that one reason why they used a 'robot' to perform the testing?

Removing that variable from the equation gave them a more controlled and equitable comparison didn't it?

The protection pad is a good point. How often are you replacing that pad though. Does it last 20 discs, 50, or less?
Still it's cost should be factored into that of the disc against those papers which do not require a pad.

I received an email earlier today from Taylor Toolworks that they have 3M Xtract Sanding Disks 25% off, link is here.



I may try some out.

If you have your own robot sander sanding flat panels all day and material removal rate/cost per gram is your primary concern then great. I get the testing and the trying to even the playing field. However, the cost per gram can be considerably skewed in real world environments. That's the world I live in. The video does a good job doing what they did and dont dispute the findings based on the test parameters.  Just because a race car may do well on a paved track doesn't mean its the best option on a motocross track.
