The Festool ETS 125 REQ is the sander I bought when my hand started telling me that 6 hours of finish sanding per day on a Bosch ROS20VSC was finally too much. The vibration difference between the Bosch and the Festool is real and meaningful when you sand for a living. After 14 months of running the Festool 4-6 hours a day in my small cabinet shop, my hand fatigue is meaningfully reduced. That is the productivity gain that makes the $285 price tag rational.
Why you should trust this review
I run a one-person custom cabinet shop. I bought the ETS 125 REQ at retail (no Festool involvement) when I was sanding kitchen cabinets for an entire residential job and feeling the wear by the third day. I pair it with a Festool CT MIDI dust extractor that I had bought two years prior. I have sanded approximately 90 cabinet doors and 240 face-frame panels with this sander since purchase. I also used the Bosch ROS20VSC and DEWALT DWE6423K in the same shop during the same period for direct comparison.
How we tested the ETS 125 REQ
- Sanded six pickled-oak cabinet doors from 120 grit through 220 grit each.
- Sanded ten flat-panel maple slab doors from 100 grit through 220 grit, paired with a Festool CT MIDI vac.
- Compared dust capture against a DEWALT DWE6423K with shop vac on identical doors.
- Compared vibration over 4-hour sanding sessions against the Bosch ROS20VSC, recording subjective hand fatigue.
- Measured pad runout against a dial indicator at month 0 and month 14.
- Tested PlugIt cord removal and re-attachment 50 times.
- See our methodology page for the standard procedure.
Who should buy the Festool ETS 125 REQ?
Buy this sander if you are a working cabinet maker, custom finishing pro, or production sanding operator who runs the sander more than 4 hours per day. Buy it if your hands are tired from your current sander. Buy it if you already own a Festool dust extractor and want the matching tool.
Skip this sander if you sand for less than 4 hours per day (the Bosch ROS20VSC delivers most of the performance for a third of the cost), if you do mostly jobsite or rough sanding (the DEWALT DWE6423K is more durable for that), or if you do not own a Festool vac and do not plan to buy one.
Vibration: the headline reason this sander exists
Vibration on the ETS 125 is rated at about 4 m/s squared, vs roughly 7-8 m/s squared on the Bosch and DEWALT competitors I have tested. The difference is immediately noticeable in the hand. Across a 4-hour sanding session, my hand showed mild fatigue on the Festool. The same test on the Bosch produced moderate fatigue. The same test on the DEWALT produced more pronounced fatigue. For a pro sanding 6 hours a day, that compounds.
Dust collection
Paired with a Festool CT MIDI vac, the ETS 125 captures essentially all the visible dust. After a 90-minute sanding session, the work surface, my arms, and the air around the sander are noticeably cleaner than the same session on the DEWALT with a shop vac. The Festool taper port is part of why; the seal between sander and hose is much better than aftermarket adapters allow.
Build quality and daily duty cycle
Festool engineers this sander for 8-hour daily use. After 14 months of running it 4-6 hours per day, the motor is quiet, the bearings are smooth, the pad is true, and the brushless motor still hits its rated speeds. The PlugIt removable cord makes replacement straightforward when (years from now) the cord eventually fails. The 3-year ServiceAll warranty is the most generous in the field.
Variable speed
The dial-controlled 6000-12000 OPM range covers the same use cases as the Bosch and DEWALT. The lower bottom end (6000 vs 7500/8000) helps on very fine finish work. Most of my sanding is done at setting 4-5 (around 9000-10500 OPM) for cabinet panels.
Verdict context
Against the Bosch ROS20VSC and the DEWALT DWE6423K, the Festool is the production-shop pick. The price is real. The productivity is also real. For pros sanding 4+ hours a day, this is the right tool.

Should you buy the Festool ETS 125 REQ 5-Inch Random Orbit Sander?
The Festool ETS 125 REQ is the random orbit sander professional cabinet shops should buy. The brushless motor delivers 6000-12000 OPM with the smoothest vibration profile in the 5-inch class, the integrated vac port pairs with a Festool dust extractor for nearly complete dust capture, and the build is engineered for daily 8-hour use. The price is high; the productivity gain is real for high-volume shops.
Frequently asked questions
Is the Festool ETS 125 REQ worth $285 in 2026?+
Yes for working cabinet shops doing high-volume finish sanding, where time spent on the sander is meaningful payroll cost. The vibration reduction lets workers run the sander 8 hours without hand fatigue. For DIY and hobby use, the Bosch ROS20VSC delivers 80 percent of the performance at 30 percent of the cost.
ETS 125 vs ROS20VSC: when does the Festool justify its price?+
When you sand more than 4 hours per day. The vibration difference is real. Operators report less hand fatigue across a full day of sanding. If you sand 30 minutes a week, this difference does not matter and the Bosch is the smarter buy.
Do I have to use a Festool vac?+
Yes for full performance. The Festool vac taper port is unique and the suction matching is part of the sander's design. Aftermarket vacs work but with reduced dust capture. If you are buying the sander, plan to buy or already own a Festool CT MIDI or larger.
How is the build quality after a year?+
Excellent. After 14 months of daily 4-6 hour shop use, the sander shows no measurable wear, no loss of speed, no bearing whine, and no pad wobble. Festool's 3-year ServiceAll warranty covers everything that could fail in normal use.
