Brushless Staying PowerThe 400 watt EC-TEC brushless motor, carbide-tipped pad brake, and constant-speed control are built for long service life, lower maintenance, and steady sanding under load.
Overview
The Festool ETS EC150/3 EQ-Plus Random Orbital Sander, Model Number 576326, is a compact 6 inch finish sander built for pros who need a high surface quality without fighting tool weight or vibration all day. This is a random orbital sander designed for fine sanding and ultra-fine finish work. If you spend your time prepping panels, sanding between coats, flattening filler, or dialing in painted and clear-coated surfaces, this is the kind of tool that earns its keep fast.
What makes this model matter is the combination of a 3 mm sanding stroke, a 6 inch pad, and controlled speed from 6,000 to 10,000 RPM. In plain terms, that means it is tuned for finish quality, not aggressive stock removal. The shorter stroke helps reduce visible swirl and leaves a more refined scratch pattern, which is exactly what you want before primer, paint, stain, or topcoat. Festool also calls out constant speed under load, so the tool keeps working consistently instead of falling off when you lean into the surface.
The physical design is a big part of the appeal. Festool built this sander with a very low overall height of 4-1/2 inches and a balanced center of gravity, which gives it a planted feel on the workpiece and better control in awkward positions. That matters on vertical panels, overhead work, and edge sanding where a taller top-heavy sander can feel twitchy. The compact body also makes it easier to keep the pad flat, which is one of the simplest ways to get a better finish.
The EC-TEC brushless motor is another real advantage for anyone who sands a lot. Brushless design helps extend motor life and cuts down on maintenance, and Festool pairs it with a sanding pad brake that uses a carbide tip for longer wear. The brake is there for a reason: it helps prevent the pad from over-revving when the tool is first set down, which can reduce gouging and help protect delicate surfaces at the start of a pass. That is one of those features you appreciate more the more finish work you do.
Dust control is also part of the system here. The tool uses a 27 mm dust extraction connection and is designed to work with Festool dust extraction setups for cleaner sanding, better visibility, and less cleanup. Cleaner extraction also means abrasive discs stay more effective and the work surface stays easier to read, which helps when you are chasing surface uniformity instead of just removing material. Festool’s approach with this tool is not just about the sander by itself, but about building a more controlled sanding process.
From an ergonomic standpoint, the numbers back up what users notice in hand. Festool lists the machine as weighing 3.53 lbs, while other seller copy highlights the very light working feel of the compact design. Either way, this is a light corded sander in the 6 inch class, and that matters on long sanding sessions. The Vibration Control System is aimed directly at smoother operation and reduced fatigue, which is a practical benefit if you are sanding doors, panels, cabinetry parts, automotive surfaces, or overhead pieces for hours at a time.
This sander is sold as an EQ-Plus kit, which means you are getting more than just the bare tool. In the box is the sander, a 6 inch backing pad, the WAF 5 screwdriver, a Plug-it power cord, and a Systainer3 SYS3 M 187 for storage and transport. That matters for shop organization and for anyone already using Festool storage and corded tool systems. The removable Plug-it cord is especially useful in a busy shop where quick pack-up, cord replacement, and tool changes save time.
Who should buy it? Cabinet shops, finish carpenters, painters doing high-end prep, millwork crews, automotive refinishing users, and serious DIYers who care about surface quality will get the most out of it. If your priority is fast heavy stock removal, you would want a more aggressive stroke. If your priority is clean finish sanding, easy handling, and low-fatigue control, the Festool ETS EC150/3 EQ-Plus Random Orbital Sander is right in its lane.
Built for Overhead and Vertical Sanding
This is where the low-profile design pays off. When you are sanding a vertical panel or reaching into an awkward position, a compact sander with balanced weight is a lot easier to keep flat and under control.
- Only 4-1/2 in. high for better access and a lower center of gravity
- Vibration Control System is designed to reduce fatigue during extended sanding
Cleaner Sanding, Better Surface Read
Finish sanding is easier when dust is not covering the workpiece. Pairing this sander with extraction helps keep the surface visible, reduces cleanup, and supports more consistent sanding results.
- 27 mm dust extraction connection for integration with Festool dust extraction setups
- 6 in. MULTI-JETSTREAM style pad system supports efficient dust movement at the pad
Finish-Focused Control in a Compact Body
The 3 mm stroke is what separates this tool from a more aggressive general-purpose sander. It is tuned for fine sanding where surface quality matters more than raw removal speed.
- 3 mm sanding stroke helps produce a high-quality finish with a refined scratch pattern
- Stepless variable speed from 6,000 to 10,000 RPM lets you match sanding speed to the material and abrasive

Pro Tip
If you are stepping down from a more aggressive sander, let the 3 mm stroke do finish work instead of forcing removal with extra pressure. Keep the pad flat, back off the pressure, and use the speed control to match the abrasive so you get the clean finish this model is built for.
