The ergonomic cordless corner sander.

The new RTSC 400, DTSC 400, ETSC 125 cordless compact sanders ensure unparalleled mobility and ease of movement when working. The powerful 18 V battery pack with 3.1 Ah 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 battery pack can be replaced with the plug it-mains adapter to achieve an unlimited running time – ideal for stationary applications and in combination with a Festool mobile dust extractor.
