sanding pad for ETS EC 150/5
« on: October 15, 2021, 02:24 AM »
Hi I'm new on this forum  [smile]

I was wondering if it's possible to install a 125 sanding pad to the Festool ETS EC 150/5 orbital sander.

Thanks,
Stefano.

As I understand it, no, a 150 pad can be installed on the 125 sander, but not the other way round.
There are a few threads in here discussing the differences.

And, welcome to the forum.

Like Pixelated noted, the shape of the pad mounting driveshaft is the issue.

Here's an ETS EC 125 with the pad removed, note the shape of the end of the driveshaft.




The 125 pad on the left and the 150 pad on the right. The 150 pad has room for the additional "ears" that are on the 150 driveshaft. So, a 150 pad fits a 125 however a 125 pad will NOT fit a 150.

It never ceases to amuse me that almost everything under the skin of a 125/3 is stamped "150/3".

I seemingly remember it having something to do with with the pad brake also??

Out of curiosity couldn't one modify the 125 pad with a pencil grinder so it would fit onto a 150 sander? Or just change the driveshaft? There are times I would like a 125/5 sander as the Pro 5 is weak (Mine lives with an edge guide on it). Warranty would be the reason not to, but that only lasts 3 years.

Ya, on my first go-around with Festool service they said the pads were not interchangeable, the 2nd time they said there was an imbalance issue between the pads and then the 3rd time they said the brake wouldn't work.

After all of that obfuscation & smoke, I just attached the larger pad and used the sander. Well, 5 years later everything works fine and I've not had any issues.

I wouldn't really try modifying the 125 pad because there isn't much material to work with there, better to change out the driveshaft on the 150 instead. That's the route I was going to take if I wanted to use the 150/5mm stroke sander with a 125 pad. I think it was only $40 to do that.
