The Festool 578985 Granat Delta 100 x 150 mm P100 Grit Abrasive Sheets (50-Pack) deliver high-performance stock removal and surface preparation on tough coatings, fillers, and clear coats. Engineered with a blend of hardened aluminum oxide and ceramic grit, these delta-shaped abrasive sheets feature a StickFix hook-and-loop backing for fast, tool-free changes on Festool DTS 400, DTSC 400, and DS 400 orbital sanders. Designed for painters, drywallers, joiners, and woodworkers, this P100 coarse grit abrasive is ideal for sanding repair compounds, fillers, hard base layers, and high-VOC clear coats.

Each sheet features a high-tech anti-clogging coating that resists dust accumulation and smearing when working on challenging substrates. By preventing premature loading, the Granat abrasive maintains a consistent cut rate throughout its service life, reducing material consumption and saving working time on intensive surface prep.

The convex edge design and triangular point allow smooth, precise sanding along rabbets, narrow profiles, and tight interior corners without damaging adjacent surfaces. Manufactured to strict FEPA standards, the uniform grit distribution produces consistent, predictable sanding results across wood, plastics, mineral materials, and repair compounds.
