The new RTSC 400, DTSC 400, ETSC 125 cordless compact sanders ensure unparalleled mobility and ease of movement when working. The powerful 18 V Bluetooth® Ergo battery pack with 3.0 Ah guarantees power similar to that of a mains-powered tool. And it is the key to an extremely compact design with balanced weight distribution and perfect ergonomics with a weight of just 1.4 kg. The integral dust extraction system, in combination with the long-life dust collection bag, enables the machine to be used flexibly – effortlessly even overhead, vertically or in hard-to-reach areas. The Bluetooth® battery pack ensures simple working in combination with a Bluetooth®-compatible Festool mobile dust extractor and ensures that the extractor starts automatically in AUTO mode when the cordless sander is started up. The battery pack can be replaced with the plug it-mains adapter to achieve an unlimited running time – ideal for stationary applications and also in combination with a Festool mobile dust extractor.
