ETSC 125 cordless vs ETSC 150
« on: February 14, 2021, 08:41 PM »
My ROS failed recently so I need get a replacement.  I have a Rotex but I don't like using it for an extended amount of time.  That ETSC 125 cordless from the recon sales keeps calling me to buy it but but I'm very weary of getting a 5" model after being so used to using a 6".  For those with the 5" cordless model and have used a 6" model before do you find the sanding process taking much longer and does it become frustrating? Is the cordless convenience worth the loss of surface area?

First off there is an ETSC 125 and an ETS EC 150, there is no ETSC 150.  [smile]

I have both the ETSC 125 and the ETS EC 125 that I use a 150 mm sanding pad on. The ETS EC with the 150 mm pad does remove material faster than the same sander with the 125 mm pad. That just makes sense. I switch between pads depending upon what my needs are.

However, there will be a large difference in material removal if you compare the ETSC 125 to the ETS EC 125 because the ETS EC 125 has almost twice the power while also having a 3 mm versus 2 mm sanding orbit. Swap out the 125 pad for a 150 pad and the material removal rates become even larger between the 2 sanders.

Thanks Cheese.  I can't keep track of all the names.  How does the ETSC with the 6" pad hold up with sanding?  Does it bog down alot?  I'll be using it for finish sanding mostly 150 and higher.  How is the DC with bag and how often do you have to change batteries?  I ordered the RTS cordless kit and if I get the ETSC can I get away with just getting the basic or will I need the extra batteries

The ETSC is strictly a 5" sander, a 6" pad is not available.

The ETS EC 125 sander WILL ACCEPT a 5" or a 6" pad. An ETS EC 150 WILL NOT ACCEPT a 125 pad.

Both the ETS EC 125 and ETS EC 150 are 400 watt machines, that's the reason they work well when the pad sizes are swapped out because there is no difference in power between the two of them.

The ETS EC sander series was designed to be low profile for ease of use in body work repairs. In order to lower their height, the internal dust collection blower was removed so they MUST be used with a dust collector...a dust bag is NOT an option.

The ETSC series sanders have an internal dust collection blower and can be used with either a bag or a vacuum. Both options work well however the ultimate is obviously the use with a dust collector.

Batteries for me will last 30-45 minutes. Which I think is reasonable because after about 15-20 minutes, I'll shut it down and check the surfaces and just get an overall feeling on how things are progressing, meanwhile I'll have a couple of batteries already charged and ready to go. It also depends upon the material you're sanding and the grit you're using. Maple with 40 grit will give you less run time than cedar with 220 grit.

I ordered the DTSC full kit and then later purchased the ETSC basic kit. That works fine as most of the time you'll not be using both sanders at the same time. So, 2 cordless sanders with 4 batteries plus an ERGO power adapter, your arm will wear out before the power supplies will.

@Cheese Do you notice any performance difference when using the 6" vs the 5" pad on the cordless version?  Does it bog down any? How is the dust collection of the bag?

Jussi, I know it gets confusing but...the cordless DTSC sander is 5" diameter ONLY there is NOT a 6" optional pad for it.

If you want to swap out pad diameters, then the corded ETS EC sander is your only choice.

Ah ok.  Sorry I misread you initial statement and thought both models can take the 6" pad.
