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