Festool RTSC 400 3.0 I-Set Cordless Orbital Sander
At a Glance: 18 V cordless orbital sander with 80 x 130 mm sanding pad, 2 mm sanding stroke, Bluetooth Ergo batteries and plug-it mains adapter for continuous sanding.
The Festool RTSC 400 3.0 I-Set is a compact cordless orbital sander designed for fine sanding, finishing work and detailed surface preparation where freedom of movement matters. With its 18 V Bluetooth Ergo battery pack, brushless EC-TEC motor and balanced one-handed design, this sander gives you cable-free control for vertical surfaces, overhead work, window frames, door frames, narrow panels and awkward areas. The rectangular 80 x 130 mm sanding pad makes it especially practical for edges, corners and smaller flat surfaces where a round sander is not always the best fit.
The RTSC 400 3.0 I-Set gives you the best of both worlds: battery-powered sanding for mobility and a plug-it mains adapter option for longer, continuous sanding sessions. It is a clever Festool sanding solution for mobile site work, workshop finishing and dust-controlled indoor sanding.

Pro Tips
- Use the cordless setup for quick mobile jobs, then switch to the plug-it mains adapter when doing longer indoor sanding sessions.
- Use the protector when sanding close to glass, frames, panelling or finished edges to help prevent accidental scuffing.
- For the cleanest finish, work through the abrasive grits gradually instead of jumping from coarse to fine.
- Keep the sander flat on the surface and avoid pressing too hard; light, even pressure produces a better sanding pattern.
- Connect a suitable Festool dust extractor when sanding paint, filler, MDF or other dusty materials indoors.
How to Use
- Fit the correct 80 x 133 mm abrasive sheet to the StickFix sanding pad.
- Insert a charged Festool 18 V Ergo battery pack, or fit the plug-it mains adapter for continuous mains operation.
- Attach the long-life dust collection bag or connect a compatible Festool dust extractor.
- Fit the protector if sanding close to edges, frames or adjacent surfaces.
- Select the correct speed setting for the material and sanding task.
- Place the sanding pad flat on the workpiece before switching the machine on.
- Guide the sander evenly across the surface with light, controlled pressure.
- Move progressively through the required abrasive grits until the desired finish is achieved.
- Allow the sanding pad to stop before lifting the machine from the surface.
- Remove the battery or disconnect the mains adapter before cleaning, changing accessories or storing the machine.
