Festool RTS 3-1/8-in. x 5-1/4-in. Granat PROfile Abrasives, 10-Pack

The Festool 3-1/8" x 5-1/4" (80 x 133 mm) 500-600 Superfine Grit Granat Profile Abrasive Sheet, 10 Pieces is a soft foam-backed sanding abrasive made for finish work where flat sheets do not do the job well. This is a foam-backed abrasive sheet designed for precision sanding on contours, profiles, and detailed surfaces. Model number 578802 uses Festool's Granat abrasive on a flexible polyurethane foam base to help painters, finish carpenters, cabinet shops, and serious woodworkers prep shaped parts without flattening the profile.

What matters here is the way the abrasive follows the work. Festool pairs a superfine P500-P600 grit surface with a 1/2" (13 mm) foam layer, so the sheet can ride over curved trim, radius edges, raised panels, and turned parts while keeping even pressure across the contact area. That means less risk of cutting through corners, less hand-finishing after machine sanding, and a more consistent scratch pattern before final coating or between coats.

This is not a general-purpose heavy stock removal abrasive. It is built for controlled surface preparation, especially on detailed woodwork and finish-sensitive materials. If you are sanding modern clear coats, painted surfaces, acrylics, fillers, repair compounds, or solid surface materials, the Granat abrasive matters because it is known for staying effective across a broad mix of materials instead of loading up fast and forcing constant sheet changes.

The 3-1/8" x 5-1/4" (80 x 133 mm) format is sized for specific Festool detail and profile sanding platforms, including the RTS 400, RTSC 400, RS 400, RS 4, LS 130, HSK-A 80x130, and HSK 80x133. Used with the right sander, this sheet gives you machine sanding control in places that usually send you back to hand pads. That is the real advantage: better repeatability on profiled work, especially when you have a lot of parts to prep and need them all to match.

On the job, that translates into faster prep on cabinet doors, trim packages, furniture components, and restoration work with shaped edges. The soft foam backing helps maintain contact on contours, but it also cushions the cut, which is useful when you are refining a surface rather than trying to reshape it. For finish sanding and in-between-coat work, that softer contact is exactly what keeps details crisp instead of washed out.

If you already run compatible Festool sanders and do detail sanding on moldings, profiled rails, decorative trim, or curved furniture parts, this abrasive makes sense. It is best for users who care about finish quality and need machine efficiency on hard-to-reach or hard-to-sand shapes. For flat panel sanding, standard abrasive sheets are the better buy. For contours and profile work, this is the right specialty abrasive.
