The Festool 578992 Granat Delta 100 x 150 mm P400 Grit Abrasive Sheets (50-Pack) deliver ultra-fine finish sanding and delicate surface preparation on repair compounds, fillers, modern paint systems, VOC clear coats, and hard sublayers. Formulated with a premium composition of hardened aluminum oxide and ceramic grit, these delta-shaped abrasive sheets feature a StickFix hook-and-loop backing for fast, tool-free sheet changes on Festool DTS 400, DTSC 400, and DS 400 orbital sanders. Engineered for painters, joiners, drywallers, and finish woodworkers, this P400 ultra-fine grit abrasive produces an exceptionally smooth, scratch-free surface prior to final clear coating or paint application.

Each sheet is manufactured with an advanced anti-clogging high-tech coating that resists dust loading, clogging, and smearing when working on challenging substrates like scratch-resistant coatings and high-VOC clear coats. By maintaining an open cutting surface throughout use, Granat abrasives deliver a consistent scratch pattern and extended service life, minimizing material consumption and reducing labor time on fine finish prep work.

The convex shape and pointed triangular tip allow precise, effortless sanding along edges, rabbets, and tight interior corners without marring adjacent surfaces. Manufactured to strict FEPA standards, the uniform grain distribution ensures reliable, predictable surface quality across solid wood, plastics, mineral materials, acrylics, and repair fillers.
