Festool Cordless delta sander DTSC 400-Basic

The Festool DTSC 400‑Basic is a high‑performance cordless delta sander engineered for maximum mobility, precision, and workstation flexibility. Designed for cabinetmakers, finish carpenters, painters, and renovators, this compact triangular‑pad sander delivers the same power, balance, and sanding quality as its corded counterpart—while offering full cordless freedom through Festool’s 18V Ergo battery platform.

The DTSC 400‑Basic features a 100 × 150 mm delta pad ideal for edges, corners, and detailed surfaces. Its brushless EC‑TEC motor and ergonomically balanced battery system provide consistent, high‑quality sanding with up to 30 minutes of runtime at full power using the 18V 3.0 Ah Ergo pack (sold separately). Hybrid operation is supported as well: simply swap the battery for the optional plug‑it mains adapter to achieve unlimited corded runtime when needed.

Festool’s integrated Protector guard allows sanding up against abutting surfaces—such as window frames, trim, and panels—without damaging the surface or pad. The tool’s Jetstream‑compatible dust extraction system, removable dust bag, and long‑life chip collection bag ensure cleaner work areas even in fully cordless setups.

For tradespeople needing a lightweight, one‑handed detail sander that excels in tight spaces and produces Festool‑grade finish results, the DTSC 400‑Basic offers exceptional performance and flexibility.
