ETS EC 125/150?

[cpap]

Thanks for all the info. I based my purchase on this and picked up the ecs ec 125/3 and a 150 pad ....and saved $50! Works perfectly!

I am new to festool and replacing my old Dewalt 5" so I am already more comfortable with the 125.  I am very interested in the fact I can get the 125 and upgrade to a 6" pad if I desire to do so later.  After reading this post many times my question is related to reply #36 from Cheese that states one of the differences between the 125 and 150 is bearing assembly.  It seams to me that that would be an important difference???

oops - I meant reply #33

First off... [welcome] to the FOG.

Now to your question, the ETS EC 125 & 150 use different pad mounting geometries, thus the 125 assembly is different than the 150 assembly only because of the different mounting shaft styles, that's the only difference. Check out the photos below and it becomes more obvious.

Just to add/clarify [member=44099]Cheese[/member] reply. I think the inference was the bearing assembly  on the 125 is somehow different and maybe weaker than the 150. This isn't the case it's simply the "keyed" shape at the end of the shaft that interfaces with the bearing is different, not the assembly as a whole.

Thanks Cheese and Bobfog for the clarification.  I see now that the key is part of the bearing shaft.

I purchased a new 125/3 yesterday and just took the pad off to take a look.  It is identical to your pictures with the same 150/3 markings on what look like some balance weights.  I will probably go get a 6" pad tomorrow and try it out.

Swap pads and just enjoy the sander...it's phenomenal, the pad brake is my favorite feature. 

It's a real shame that Festool didn't incorporate quick-change pads with this sander so that it could be quickly converted from 125mm to 150mm.  That was a real bone-head marketing decision.
The Festool engineering acumen...usually exceptional, the Festool marketing acumen...not so much.

Got the 6" pad on my ETS EC 125 now and it works great.  Seams to start and stop just fine.  I feel so dirty but I will get over it.  Thanks again for the tip.

Dang. I bought an ETS EC 150/3 over 30 days ago and sadly havent even had a chance to use it. I wish I would have found this thread first though as I certainly would have like to consider getting the ETS EC 125/3 had I known I could just buy 150 pads and use them when I needed. That sucks. Kinda wondering if Acme Tools would still exchange it seeing as how I havent used it yet...

File a 90-day return protection claim with your credit card company!  That's a pretty standard feature.

Ha wow! Have to decide it its really that serious. I do have the Pro 5 LTD too for finishing and finer work... Maybe I should just stick with the EC 150/3.

. I'm pretty sure the Pro 5 has a 3mm orbit, which would match a 150/3 in specs, but the EC's do seem to get a job done faster even with a finer than 5mm orbit .

 

[weekendwarrior]

Can you use a 150 pad with the Pro 5 LTD?

 

[leakyroof]

. Have no idea...I'm still waiting for my Pro5 to show up.... [doh]

I can't for the life of me believe that an additional 50 watts of power makes that much difference in the performance of the sander...but something really works well here. My Pro 5 is a lot better in removing previously applied finishes.

Maybe if you can find a 150 pad that will fit it. Festool does not have a 150 pad that will fit the Pro 5

It has a 2mm stroke.

Anyone want to trade their ets ec 125 for my pro5 and an ets ec 150 without the pads?  Lol  [crying] [unsure]

You could easily sell those two and buy the ETS EC 125/3.

There is a lot to be said for a 5-mm stroke.
The difference between 2 and 3-mm stroke and 50 extra watts, is eclipsed by a 5-mm stroke and an EC motor.

But if one wants a 5-mm stroke in 125-mm diameter, then it requires the Mirka... or some other brand.
