The new ETSC 125, RTSC 400, DTSC 400 cordless compact sanders ensure unparalleled mobility and ease of movement when working.

The powerful 3.0 Ah 18 V Bluetooth® Ergo battery pack 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.

For unlimited running time, the battery pack can be replaced with the plug-it mains adapter – ideal for stationary applications and also in combination with a Festool mobile dust extractor.

  • Mobile and effortless: Without cable and hose, with perfect ergonomics, low height and a weight of just 1.4 kg
  • Powerful: The 18 V battery pack in combination with the brushless EC-TEC motor ensures power similar to that of a mains-powered tool
  • No interruptions: Thanks to battery packs with a capacity of 3.0 Ah which run for longer than their charge time
  • Unlimited running time: For continuous electrical operation, the battery pack can be replaced with the plug-in mains adapter (included in the set and available as an accessory)
  • A dust-free, healthy working environment: With the long-life dust collection bag made from extra-durable nonwoven polyester or in combination with a Festool mobile dust extractor
  • Less rework: PROTECTOR for smooth 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 to the CT 26/36/48 as an accessory, directly integrated into the CT MINI I and MIDI I) and starts the mobile dust extractor automatically when the cordless sander is switched on.

Main applications

  • Cable-free sanding where there is no power connection or where this is difficult to access (e.g. outdoors, on scaffolding)

  • Ideal for vertical surfaces or overhead work
  • One-handed sander for small and narrow surfaces
  • Sanding off paint and varnish on window frames, door frames and eaves
  • With plug it-mains adapter as a sanding machine with an unlimited running time during continuous electrical operation – ideal for use indoors in combination with a Festool mobile dust extractor
