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.
