This is a cordless orbital sander designed for finish sanding on wood, paint, filler, and similar surface materials. Model Number 576346. If you want Festool sanding performance in a lighter, more maneuverable format that can work on a battery or with an optional AC adapter, this is the tool.\u003c\/p\u003e \u003cp\u003eThe big selling point here is the hybrid setup. You can run the RTSC 400 cordless with a Festool 18V Ergo battery for mobility on punch-list work, trim installs, cabinet touch-ups, and site sanding, or switch to the optional AC adapter when you are parked at a bench and do not want to think about runtime. That kind of flexibility is not a gimmick. It means the same tool can handle quick service calls and longer sanding sessions without forcing you into one power setup.\u003c\/p\u003e \u003cp\u003eFestool also built this sander around balance and user comfort. The low-profile body, compact footprint, and ergonomic battery arrangement help keep the center of gravity close to your hand, which makes the tool easier to guide on vertical surfaces, face frames, doors, and narrow parts. Supplementary product data also calls out a brushless EC-TEC motor, which helps explain why the RTSC 400 is positioned as a cordless sander with corded-level performance rather than a light-duty trim tool.\u003c\/p\u003e \u003cp\u003eFor finish work, the rectangular pad shape is the right call when you need to work up to edges, flatten smaller panels, or sand in tighter spots where a random orbit sander with a round pad is less efficient. The interchangeable sanding pad measures 3-5\/32 inches wide by 5-1\/4 inches long, and the sanding stroke is 5\/64 inch. In practical terms, that gives you a controlled finish-sanding pattern suited to prep work between coats, final surface refinement, and sanding near corners and trim details.\u003c\/p\u003e \u003cp\u003eDust handling is another strong point. The Festool 576346 RTSC 400 18V Brushless Hybrid Cordless Sander BASIC includes a long-life dust bag, and Festool specifically highlights effective dust extraction as a core feature. Less airborne dust means better visibility on the work surface, cleaner interiors, and less contamination when you are working around stain-grade trim, painted built-ins, or finished spaces. If you already run a Festool extractor, this sander fits right into that cleaner workflow.\u003c\/p\u003e \u003cp\u003eThe included protector is not just an accessory tossed in the box. It is there to protect both the pad and adjacent finished surfaces when you are sanding right up against an edge or neighboring component. That matters for cabinet installers, finish carpenters, and remodelers doing punch work where one slip can leave a mark on an already-finished piece. Festool clearly designed this tool for close, controlled sanding rather than broad stock removal.\u003c\/p\u003e \u003cp\u003eCompatibility is important with this model. The BASIC version does not include a battery, charger, or AC adapter, and supplementary data states that it is only compatible with Festool 18V Ergo batteries. That is worth knowing before you buy. If you are already on Festool's sanding and dust extraction system, the RTSC 400 slots in easily. If you are not, make sure you are budgeting for the power setup you need.\u003c\/p\u003e \u003cp\u003eThis sander makes the most sense for finish carpenters, cabinet installers, woodworkers, painters, and remodelers who care about control, low fatigue, and clean results. It is not the tool you grab for aggressive material removal on large rough surfaces. It is the one you reach for when the surface is visible, the edge is close, and the finish actually matters.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\u003csummary\u003e\u003ch2\u003eCompact Control for Finish Work\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"img\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0933\/1582\/5958\/files\/50175728714022_2af684a802b4.jpg\" alt=\"Festool 576346 RTSC 400 18V Brushless Hybrid Cordless Sander BASIC shown with dust bag attached for finish sanding on trim and panel work in a shop or jobsite setting\" class=\"tnblock-img\"\u003e \u003c\/div\u003e \u003cdiv class=\"copy\"\u003e\n\u003cp\u003eThis sander is built for the kind of work where feel and control decide the final result.
