Festool DTSC 400 - The Delta Sander That Reaches Where Others Can't

Meet the problem-solver: the Festool DTSC 400 delta sander designed for the places flat sanders simply can't reach. This isn't just another sander—it's your key to flawless corners, tight angles, and intricate details that separate professional work from amateur results. With its triangular 100x150mm pad and cordless freedom, it gets into corners like a whisper and leaves surfaces like glass.

Precision That Fits in the Tight Spots

While orbital sanders glide across open surfaces, the DTSC 400 specializes in the places most tools avoid. The delta-shaped head slips into corners, reaches behind trim, and sands right up to edges without marring adjacent surfaces. The 2mm sanding stroke ensures swirl-free finishes even in the most visible details, while the 6,000-10,000 orbit speed adjusts to everything from delicate veneers to aggressive material removal.

Weighing exactly one kilogram without battery, this delta sander feels substantial enough for control yet light enough for overhead work and detailed tasks. The Bluetooth connectivity remembers your preferred settings for different applications—whether you're fine-tuning cabinet interiors or prepping intricate moldings for finish. This isn't a sander that fights for space; it's one that creates possibilities in tight quarters.
