Festool Cordless delta sander DTSC 400 3,0 I-Set Description

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.

Product details

Maximum mobility

Work effortlessly overhead, vertically or in hard-to-reach areas – without power cable and hose, with perfect ergonomics and a weight of just 1.4 kg (including battery), perfectly balanced weight distribution and low height.

Powerful and durable

The powerful 18 V Bluetooth® Ergo battery pack in combination with the brushless EC-TEC motor ensures constant sanding and power similar to that of a mains-powered tool.

Work without interruptions

Thanks to the Bluetooth® battery packs with a capacity of 3.0 Ah and a longer running time than charge time.

Simply communicative

The Bluetooth® Ergo 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 tool is switched on. In this way, you also benefit from the complete Festool dust-free system when working with the cordless sander.

Unique: With battery or cable

For all applications which require an even longer operating performance, the 18 V Bluetooth® Ergo battery pack can be replaced with the plug it-mains adapter (included in the set version and available as an accessory). This alone creates a mains powered machine with an unlimited running time in combination with the plug it-cable – ideal in conjunction with a Festool mobile dust extractor.

A dust-free, healthier working environment

With the long-life dust collection bag (can be emptied and reused) made from extra-durable nonwoven polyester or in combination with a Festool mobile dust extractor.

Reliable extraction with the new CLEANTEC connecting system

The integrated bayonet fitting connects the connecting sleeve on to the dust bag or the suction hose securely and quickly to the extractor connector on the power tool, and it can be detached just as quickly. You decide when, not chance.

A perfect fit for your hand

Comfortable handle thanks to its soft grip and ergonomically perfect switch position for both left- and right-handed operators.

Less reworking

PROTECTOR for smooth sanding along window surfaces, frames and panelling.

Systems get it done

Achieving the perfect surface quality depends on the smallest of details. This is why Festool supplies suitable abrasives for every application and material. For guaranteed cost-effective work with perfect results, from coarse sanding to fine sanding.

About Festool Tools
Festool makes most sense when tools, extraction and accessories are chosen as parts of one working sequence. This catalogue spans dust extractors, joining and edge-banding equipment, sanders, saws, routers, cordless tools, energy sets and system accessories, so the useful starting point is the job you want to complete rather than a single model name.
