Overview
The Festool 576822 ETSC 125 18V Brushless Hybrid Cordless 125mm (5-Inch) Sander BASIC is built for finish sanding where control, mobility, and surface quality matter more than brute force. This is a cordless random orbit sander designed for finish sanding, surface prep, and close-edge work. Model Number: 576822. If you move from shop benches to punch-list work to installed trim, this setup makes sense because it gives you the freedom of battery power without giving up the option to run corded with the appropriate adapter.
What makes this sander stand out is the hybrid power approach. Festool designed the ETSC 125 so you can work cordless when a cord gets in the way, then shift to corded operation when continuous runtime is the priority. On battery power, Festool states the 18-volt Ergo battery provides up to 30 minutes of runtime at full power. That matters for real jobsite sanding because it covers a lot of detail work, finish passes, and between-coat sanding without dragging a hose and cord everywhere. When you are set up in the shop or on a longer session, the optional A/C adapter gives you a path to continuous operation.
The sanding performance is set up for finish-quality work rather than aggressive stock removal. With an eccentric motion speed range of 6,000 to 10,000 RPM and a 2 mm sanding stroke, this 5-inch random orbit sander is aimed at producing a refined surface on wood, painted material, and similar finish-sensitive applications. That smaller stroke is the kind of spec that matters if your goal is fewer swirl marks and better control on final passes.
Festool also kept the tool compact and light. The official technical data lists the bare tool weight at 1.98 lbs, which is a big deal on vertical work, overhead touch-ups, and long sessions on trim or face frames. The Ergo battery design is not just a packaging trick. Keeping the battery shape low and integrated helps the sander stay balanced in the hand, so it feels less top-heavy and easier to guide across a finished surface.
Dust control is another real selling point here. The ETSC 125 uses Jetstream dust extraction and includes a reusable dust bag, plus it has a 27 mm dust extraction connection for use with Festool dust extraction setups. Cleaner sanding is not just about housekeeping. Better dust removal helps the abrasive keep cutting, reduces loading, and makes it easier to see what the surface actually looks like while you work. That matters when you are sanding stain-grade material, painted trim, or between coats where one missed scratch shows up later.
For edge work and sanding near adjacent finished surfaces, Festool includes its removable Protector. This part protects both the sanding pad and nearby surfaces during close-up sanding. In practical terms, that means you can get near corners, walls, installed trim, or other finished parts with less chance of bumping and scuffing something that is already done. That is the kind of feature that saves time on touch-up work and lowers the risk of creating extra repair work for yourself.
The BASIC version is important to understand before you buy. You get the sander, a StickFix soft sanding pad, edge protector, reusable dust bag, and a Systainer storage case. You do not get the A/C adapter, batteries, or charger in this version. That makes it a smart buy for users who already own compatible Festool power accessories or who specifically want the bare tool and storage without paying for duplicate charging gear.
Who is this for? Cabinet installers, finish carpenters, painters, remodelers, woodworkers, and serious DIY users who care about surface quality and clean sanding. If your work includes final surface prep, sanding in occupied spaces, or working around installed material where cords are annoying and control matters, the ETSC 125 is a strong fit. If you need aggressive removal over large areas all day, you would look at a different sanding setup. If you need a lightweight finish sander that works clean and stays easy to handle, this one is right in its lane.
Festool 576822 ETSC 125 18V Brushless Hybrid Cordless 125mm (5-Inch) Sander BASIC in Real Use
This is where the hybrid design earns its keep. You can set the sander up for mobility when you are moving around installed work, then configure it for longer sanding sessions when you want continuous operation.
- Hybrid design supports cordless use and optional corded operation
- Built around an 18V Ergo battery format for better balance in hand
Light Weight Means Better Finish Control
A finish sander works best when it feels easy to steer. The ETSC 125 keeps weight down and stays compact, which helps on vertical panels, edge work, and long sanding sessions where a bulky tool starts to fight you.
- Official tool weight: 1.98 lbs
- 5-inch pad size fits common finish sanding tasks and abrasive options
Cleaner Sanding, Less Rework
Dust control affects both finish quality and speed. When extraction is working, the abrasive stays cleaner, the surface stays more visible, and you spend less time brushing dust away to check your progress.
- Jetstream dust extraction supports a cleaner sanding process
- 27 mm dust extraction connection allows use with Festool dust extraction setups
Built for Close-Edge Finish Work
The included Protector is one of those features you appreciate the first time you sand near something that is already finished. It helps you work tighter to adjacent surfaces with less chance of marring them.
- Integrated removable Protector helps protect nearby surfaces and the pad
- Included Systainer keeps the tool and accessories organized between jobs

If you are sanding next to installed trim, cabinet faces, or a finished wall, snap on the Protector before your final passes. It is a simple add-on, but it helps prevent the pad edge from touching and marking the surface beside your work.
