Festool ETS 125 REQ Random Orbit Sander Review (2026): The

Why you should trust this review

I run a one-person custom cabinet shop, and I bought this Festool at retail when six hours a day of finish sanding on my old Bosch was finally too much for my hand. Festool had no involvement. I pair it with a Festool extractor I had already owned for two years, so I was set up to test it the way the tool is meant to be used rather than fighting an aftermarket vac.

Over 14 months I have sanded roughly 90 cabinet doors and 240 face-frame panels with it, running it four to six hours a day during busy stretches. I also kept a Bosch and a DEWALT in the same shop across the same period, so the comparisons below come from the same materials and the same hands, not from spec sheets.

How we evaluated

I sanded six pickled-oak cabinet doors from 120 through 220 grit and ten flat-panel maple slab doors from 100 through 220, all paired with a Festool extractor. I compared dust capture against a DEWALT on a shop vac using identical doors, and I compared vibration across four-hour sanding sessions against the Bosch while recording how my hand felt at the end. I measured pad runout against a dial indicator at the start and again at month 14, and I cycled the removable cord 50 times to check the connection.

Vibration: the headline reason this sander exists

Vibration on the ETS 125 is rated at about 4 m/s squared, against roughly 7 to 8 for the Bosch and DEWALT I have tested. That gap is immediately noticeable in the hand. Across a four-hour session my hand showed only mild fatigue on the Festool; the same test on the Bosch produced moderate fatigue, and the DEWALT produced more pronounced fatigue. For someone sanding 30 minutes a week none of this matters, but for a pro running the tool six hours a day it compounds into the difference between finishing the day comfortable and finishing it sore.

This is the entire case for the sander. The vibration profile is not a nice-to-have spec, it is the reason the price is rational for a high-volume shop. When the tool in your hand is a payroll cost measured in hours, a sander that lets the operator run all day without hand fatigue pays for itself in throughput. If you do not sand long enough to feel fatigue in the first place, you are paying for a benefit you will not collect.

Dust collection: nearly complete with the right vac

Paired with a Festool extractor, the ETS 125 captures essentially all the visible dust. After a 90-minute session, the work surface, my arms, and the air around the sander were noticeably cleaner than the same session on the DEWALT with a shop vac. A lot of that is the Festool taper port, which seals the sander to the hose far better than the aftermarket adapters I have used.

That tight integration is also the catch. The taper port is unique, and full dust performance really does depend on a matching Festool extractor. Aftermarket vacs work but with reduced capture, so if you are buying this sander you should plan to buy or already own the matching extractor. Budgeting for the sander alone and bolting it to a generic vac leaves a chunk of its advantage on the table.

Build quality and daily duty cycle

Festool builds this sander for 8-hour daily use, and after 14 months of running it four to six hours a day, it shows it. The motor is still quiet, the bearings are smooth, the pad runs true against the dial indicator, and the brushless motor still hits its rated speeds with no measurable wear. Nothing has loosened, whined, or wobbled.

The removable cord is a quiet bit of long-term thinking: when the cord eventually fails years from now, you swap it rather than the whole tool, and it survived 50 connect cycles in testing without any play. Festool’s lengthy service warranty is the most generous in the field and reinforces the impression that this is a tool bought to last a decade of professional use rather than to be replaced.

Variable speed and finish quality

The dial-controlled speed range covers the same use cases as the Bosch and DEWALT, but the lower bottom end helps on very fine finish work where a slower orbit reduces the risk of swirl. Most of my cabinet panels get sanded at a mid setting, and at every grit step the surface came up clean and finish-ready. Across the pickled-oak and maple doors, I never had to chase swirl marks after the fact.

The orbit and pad combination strikes a good balance between stock removal at the coarse grits and a smooth surface at the fine grits, which is what you want from a one-tool finishing setup. It is not a rough-removal monster, and it is not meant to be; it is a finishing sander that produces consistent, paint-ready and stain-ready results across a full cabinet run.

Who should buy the Festool ETS 125 REQ?

Buy it if you are a working cabinet maker, custom finisher, or production sanding operator who runs the sander more than four hours a day, if your hands are already tired from your current sander, and if you own or will buy a Festool extractor to unlock its dust performance.

Skip it if you sand less than four hours a day, where a value sander delivers most of the performance for a fraction of the cost. Skip it if you do mostly jobsite or rough work, where a rugged corded sander handles drops and abuse better. And skip it if you have no Festool vac and no plan to buy one, because you would be paying for an integration you cannot use.

The verdict

The Festool ETS 125 REQ is the production-shop pick, and after 14 months I would buy it again without hesitation. The vibration reduction is the real, measurable benefit that lets a pro sand all day, the dust capture with a matching extractor is close to complete, and the build has not aged at all under heavy use. The price is steep and the vac requirement is real, but for anyone sanding four-plus hours a day, this is the right tool and the productivity it buys is not imaginary.
