Festool battery and mains powered triangular sander DTSC 400 3,0 I-Set 578851

Main applications:
Wireless sanding where there is no power connection or it is difficult to access (e.g. outdoors, on scaffolding)
Mobile work when the power cable and suction hose are very disturbing during work (e.g. vertical surfaces, sanding overhead, plastering edges, etc.)
Ideal for work on vertical surfaces or overhead
One-handed sanding of small and narrow surfaces
Sanding paint and varnish from window frames, door frames and eaves
With plug it adapter as a sanding machine with unlimited operating time in electrical continuous mode, which is an ideal combination with the Festool mobile dust extractor indoors
Convenient work with a vacuum cleaner - Bluetooth® battery automatically starts the Bluetooth®-enabled mobile dust extractor in AUTO mode

The new battery-compact sanders ETSC 125, RTSC 400, DTSC 400 take care of exceptional mobility and freedom of movement during work.
The powerful 18 V Bluetooth® Ergo battery with 3.0 Ah guarantees the same power as from a power outlet. And this is the main reason that ensures an extremely compact construction with a balanced weight distribution and perfect ergonomics at only 1.4 kg.
Automatic dust extraction in combination with the Longlife dust collection bag allows the tool to be handled flexibly - it does not tire even when working overhead, in upright or hard-to-reach places. The Bluetooth® battery ensures that the work runs smoothly in combination with the Bluetooth®-enabled Festool mobile dust extractor and that the vacuum cleaner in AUTO mode starts automatically when the battery sander is switched on.
To achieve unlimited operating time, the battery can also be replaced with a plug it mains adapter - ideal for on-site tasks, also in combination with the Festool mobile dust extractor.
The Festool light module adds one important detail to your compact sander: perfect visibility.

Maximum mobility
Easy work overhead, vertically or in hard-to-reach places - without a power cord and hose, perfect ergonomics and only 1.4 kg weight (with battery), perfectly balanced weight distribution and low overall height.

Strong and durable
The 18 V Bluetooth® Ergo battery in combination with the brushless EC-TEC motor ensures consistent sanding and the same power as mains-powered tools.

Uninterrupted work
Thanks to the Bluetooth® battery pack with a capacity of 3.0 Ah, which has a longer life and operating time.

Aldis communicator
The Bluetooth® Ergo battery communicates via Bluetooth® with the Bluetooth® module of the CLEANTEC mobile dust extractor (CT 26/36/48 as an accessory to be added later, CT MINI I and MIDI I already built-in) and automatically starts the mobile dust extractor when the battery tool is switched on. This way, you also win when you use the Festool dust-free system battery sander in your work.

Unique: with battery or power cable
For any work that requires a longer duration, the 18 V Bluetooth® Ergo battery can also be replaced with a plug it mains adapter (included in the set, but also available as an accessory). In combination with the plug it cable, the device becomes a mains-powered machine with unlimited operating time - a great solution with the Festool vacuum cleaner.

Dust-free and healthier
With the Longlife dust bag (emptiable, reusable), which is made of extra durable polyester fleece, or with the Festool mobile dust extractor.

Safe dust removal with the new CLEANTEC connection system
The built-in bayonet joint connects the dust bag or suction hose connection sleeve quickly and securely to the suction nozzle of the power tool. Disconnection is just as quick. You determine the moment, not by chance.
