The RTSC 400 provides the same functionality as its corded counterpart but with hybrid power options – use it cordless or corded. Well suited for a wide range of one-handed applications, the RTSC 400 is ideal for working on flat, vertical and overhead surfaces because of its compact design and weight of only 1.4kg.
