Mobile and fatigue-free: no cables or hoses, with perfect ergonomics, a low profile and weighing just 1.4 kg. Powerful: the 18 V Ergo battery pack, combined with the brushless EC-TEC motor, delivers performance on a par with mains-powered tools. Uninterrupted: thanks to battery packs with a 3.0 Ah capacity that run longer than they take to charge. Unlimited runtime: for continuous electric operation, the battery pack can be swapped for the ‘plug it’ mains adapter (included in the set and available as an accessory). Dust-free and healthy: With the Longlife dust collection bag made from extra-durable polyester fleece or in combination with a Festool mobile dust extraction unit. Less rework: Protector for gentle sanding along window surfaces, frames and panelling. Convenient dust extraction: The battery pack communicates via Bluetooth with the Bluetooth module of the Cleantec mobile dust extractor (can be retrofitted as an accessory on the CT 26/36/48 models; integrated as standard on the CT MINI I and MIDI I models) and automatically starts the mobile dust extractor when the cordless sander is switched on. The new ETSC 125, RTSC 400 and DTSC 400 cordless compact sanders ensure unrivalled mobility and freedom of movement whilst working. The powerful 18 V Bluetooth Ergo battery pack with 3.0 Ah guarantees performance on a par with mains power. It is also the key to an extremely compact design with balanced weight distribution and perfect ergonomics, weighing just 1.4 kg. The integrated dust extraction system, combined with the long-life dust bag, allows for flexible handling of the machine – minimising fatigue even when working overhead, vertically or in hard-to-reach places. The Bluetooth battery pack ensures hassle-free operation when used with a Bluetooth-enabled Festool mobile dust extractor and ensures that the extractor starts automatically in AUTO mode when the cordless sander is switched on. For unlimited runtime, the battery pack can be swapped for the ‘plug it’ mains adapter – ideal for stationary use and also in combination with a Festool mobile dust extractor.
