## Summary

A 1 kg delta sander with a 100 × 150 mm triangular pad and 2 mm stroke that gets into corners and along glazing bars. It runs on the light 3.0 Ah Ergo pack or, for continuous work, a plug-in mains adapter.

## Why this one

- **Delta pad**: 100 × 150 mm point for corners and profiles.
- **Protector**: Sands up to glass and frames without damage.
- **Ergo battery**: Runs on the light 3.0 Ah Ergo pack or a mains adapter.
- **Brushless EC-TEC**: Mains-like power in a one-hand sander.

## The story

### Into every corner

Window and door frames, panelled doors and eaves are where painters lose time. The DTSC 400 puts a pointed pad into inside corners and along beads, while the Protector edge lets you sand up to glass and frames without chipping them. At around 1 kg bare and with a low height, it is comfortable on vertical and overhead work.

### Battery or mains

It runs on Festool's compact BP 18 Li 3.0 Ergo battery, which lasts longer than it takes to charge. For long indoor jobs, the optional ACA 220-240/18V Ergo adapter replaces the battery and makes it a corded sander. The brushless EC-TEC motor delivers mains-like power, and dust goes into a long-life bag or a CLEANTEC extractor. The Basic version comes without battery in a Systainer³.
