I know this can be done with other sanders, but I couldn’t find much about if it would work with a Festool ETS EC 125/3 EQ. Festool recommended not doing this, but I heard from a few other woodworkers that you could, so I decided to try it myself.
I actually filmed this in January 2021, just wanted to wait till I had some long-term testing to go off of before sharing it. After several months of pretty heavy use, I still haven’t had any issues or swirl marks, so feel free to save yourself $400+ on a Festool ETS EC 150 if you already have the 125.
I can’t remember the exact reasoning, but I have heard that you cannot put a 125 pad on a 150 sander. Let me know your thoughts or if you have any questions in the comments below.

Hello everyone! I just wanted to throw some info in here for you all to take in that either want to or have already switched their ECT ES 125mm to a 150mm pad. I have a Mirka Deros 650 CV that is a 150mm size sander that can also have a 125mm pad put on it. But you just don't put their Deros 625 CV 125mm pad on it, they have a dedicated 125mm "130gram" pad just for the 650 CV. The reason is this pad weighs the same as the 150mm pad keeping the sander in balance. The 125mm pad for the ETS EC weighs 101 grams, the 150mm pads weighs 148 grams, which is a 46% increase. This is a lot of weight which the ETC ES 125 was not balanced for, but the ETS EC 150 was. Now this will not only show up as a vibration that you feel while operating, and while some may not either feel it as much as others or even care, it will impact the sander. It will take a toll on the main bearing by placing an imbalance of 46% that it wasn't designed to operate with, in engineering parameters this is a "sh_t-ton" of imbalance. These vibrations can also take a toll on the electronics. I don't see it being easy to remove 47 grams of weight from the 150mm pad, but one might go the other way. Take an ETS EC 150 and place a 125mm pad on it that was modified by adding 47 grams of weight to it to balance it, but this isn't what you are trying to do so... 🤦‍♂ Just so you all know, I do own a butt load of Festool tools, so you don't think I'm just slamming Festool in any way. All the Best, Chuck

@OverkillWoodcraft Год назад

Hey Chuck, thanks for the great info! I did wonder about the potential weight difference and if it would affect performance over time. It's my most used sander and I switch between pads quite a bit and haven't seen any negative effects on the end product. Far as vibration and balance go, same results. Maybe I just haven't noticed it though, would be interesting to compare the feel of my "well-loved" Festool to a brand new, but until it starts leaving pig tails or trying to buck my hand like an angry bronco then I'll keep at it. Good to know about the Mirka pad as well, I'm considering their 5mm for my next sander so I can have something more aggressive for stock removal that isn't a two handed sander.

@toolchuck Год назад

@@OverkillWoodcraft You bet! I too would love to be able swap pads around on my Festool ETS-EC-125/3, and that is why I bought a Mirka 650-CV/5. I'm going to get an ETS-EC-150/3 so I'll have a 3mm and a 5mm in 125 and 150 sizes but only using three sanders. Yes, it is overkill to some, and myself at times, but I do see a difference in finish between the 3 and 5mm orbits. I prefer 125 as the paper is cheaper and often this size is exactly what my project calls for, but a larger area is so much easier to cover with a 150. The Mirka is a fine sander so far, it is very low and it has a really good ergonomic feel for me. They just don't have a very "solid" presence in the U.S. like Festool, so it is hard, if not impossible to get anything locally unless you buy a quantity that only shops would use. I'm in California, 30mi east of S.F., one would think that there would be a retail dealer around, but nope. Anyway, I wish you the best with the 150 pad swap, may it sand long and smooth!😎 Oh yeah, have you seen the "Workshop Dojo"? If not check him out on RU-vid, especially his video "Why you should love sanding not hate it", it's on topic and great, he's great! All the Best, Chuck

@SaintFredrocks 10 месяцев назад

@@OverkillWoodcraft I bet you still don't see any difference between the two pads. I really don't understand how 47 grams is going to make a difference when you compare the load difference between 80 grit paper and 1000 grit paper. That is going to create a good deal more changes in force. They sell three different pads of varying stiffnesses and weights for each unit don't they.

@OverkillWoodcraft 10 месяцев назад

@@SaintFredrocks Yeah I always wondered how the drag from different grits plays in. I've honestly still been using this same pad, hasn't been fully worn out yet since I switch between it, 5" quite, and my other sanders quite often. Results are still the same, which is a perfectly sanded surface.

@johnkantar3082 3 года назад

Thanks for the lesson , im about to purchase the 150/3 could you please tell me your recommendations for grits to purchase starting from 60g as festool have so many and im sure i dont need all of them.

@OverkillWoodcraft 3 года назад

Hey no problem, glad it was helpful. If you're starting at 60 grit I'm guessing it's on pretty rough stock, and in that case I'd recommend getting the 5mm stroke instead of the 3mm. It'll be better at removing those rough surfaces and because a 3mm might struggle with that it could end up leaving swirl marks/pig tails. Plus you can still achieve a nice finish with a 5mm. I'll usually send rough stock through my drum sander at 80 or 100 grit, then I run through the following: 120, 150, 180, and 220. Some argue 180 isn't necessary, but and it probably isn't for some stuff, but it'll only help either way. If starting with a ROS at 60, I'd then go: 80, 120, 150, 220 at a minimum. Ideally you could add 100 and 180 in there though if you're using a 5mm stroke.

How is yours holding up? Just picked up an ets ec 125 and installed the 150mm hard pad. Brake stops just as fast and so far seems to work exactly as the ets ec 150 would. Mfg date on mine is 2021-06

@OverkillWoodcraft 2 года назад

Nice, hope you're enjoying it! Mine is holding up great, I rarely use it with the 125 pad anymore but haven't had any issues. Just finished using it on two huge storage benches actually and I don't miss sanding stuff like that with a 5" pad haha.

@tharagz08 2 года назад

@@OverkillWoodcraft only sanded some cherry shelves. Can't believe how much faster the 6" pad is over 5". I much prefer the hard pad as well. This is all coming from my Pro 5 LTD to the ets ec. 250w and 2mm stroke to 400w 3mm stroke is crazy. And I was impressed with each step of the way when I went from my porter cable -> Dewalt-> to the pro 5 ltd, so its pretty wild how the increased efficiency and quality is still so noticeable. Glad yours is holding up, thanks again

ETS EC 125/3 with the 150 pad will no longer fit in the original 125/3 Systainer insert. However, if you happen to own a RO 150, the ETS EC with 150 pad will fit in the space intended for extra sanding discs. Store both sanders in one Systainer and you've just freed up a Systainer for other stuff!

@Lawdwarf 3 года назад

the larger pad means more load and stress for the sander, particularly the motor and the center screw. 125 to 150 mm means approx 44% more area that has to be moved by the motor. While it works, you should use it with much more care and include cool down brakes more often. Based on the info I received, mounting a bigger pad makes the sander run at the higher end of the tolerances.

@OverkillWoodcraft 3 года назад

Good insights, but they both have the same 400 watt motor thougb and are identical in every other way I know of. The only real difference I've found is the pad, so this saves roughly $450. While I try to give all of my machines breaks as needed, I haven't gone easy on this one and it's performing perfectly.

@jamesquinless1777 2 года назад

I’m pretty sure the 125 and 150 (given they’re the same mm stroke) are the same exact sander. If you think about it from a production standpoint it makes sense to make the one sanding housing and market it as two different products while making it more expensive with only the addition of a cheap pad. Seems like the path of least overhead resistance to me.

@OverkillWoodcraft 2 года назад

@@jamesquinless1777 Yeah it really is the path of least resistance I think, because they are identical. I believe the same can be done with the Mirka sanders and all the other brands with that Mirka body style too. Gotta love being a consumer lol.

@williamzetteroweriii9469 2 года назад

Question: I mostly make epoxy river type tables and wanting advice on if I should go with 3mm or 5mm. Suggestions much appreciated...Oh, I'm primarily sanding Olive wood.

@OverkillWoodcraft 2 года назад

Honestly, you might need both if that olivewood's rough. If not a 3mm should be fine. In most cases sanding under 100/120 grit with a 3mm is pointless because it's not aggressive enough for stock removal without leaving swirl marks. Not sure how high you would be sanding too, but going higher than 320, maybe 400 with a 3mm can leave swirl marks in a lot of scenarios because it's too aggressive. Once I get over 220 I use my Festool ETS 125, it has a really fine stroke of like 2mm I believe. Let me know if that doesn't help, good luck either way!
