The new cordless sanders RTSC 400, DTSC 400, ETSC 125 provide exceptional mobility in work. The powerful 18 V Bluetooth® Ergo battery with 3.0 Ah delivers the same performance as a corded model, giving the 1.4 kg light machine a well-balanced weight distribution and unmatched ergonomics. The integrated dust extraction combined with the Longlife dust bag makes the machine easy to handle, allowing you to work effortlessly overhead or in hard-to-reach places. With the Bluetooth® battery combined with a Bluetooth® compatible Festool vacuum in AUTO mode, the vacuum starts automatically when the sander is turned on. For limitless operating time, you can replace the battery with a plug-it mains adapter – perfect for stationary use and in combination with a Festool vacuum.
