The Festool STF DELTA/9 P80 RU2/50 Rubin 2 sanding sheets are a delta-shaped abrasive pack built for wood surface preparation and finish sanding. This is a sanding sheet designed for wood sanding, especially intermediate sanding, final sanding before finishing, and prep work before oiling, waxing, or varnishing. Model Number 577573. If you run a compatible Festool delta sander and do trim, furniture, cabinet, or paint-prep work, this is the right kind of abrasive for staying productive on wood instead of burning time with a generic sheet.

What matters here is not just the P80 grit, but how the Rubin 2 abrasive is tuned for wood fibers. Festool positions this abrasive as a wood-specific option that sheds material efficiently and helps reduce clogging from wood dust and pitch. The result is more consistent cut, cleaner progression through sanding steps, and less time spent changing out loaded sheets before the work is done.

Festool also claims a 30% faster removal rate and up to 30% longer sheet life compared to the original Rubin abrasive. In practical terms, that is the kind of improvement you notice when you are flattening edges, cleaning up profiles, or moving through prep sanding on doors, trim, or furniture parts. Faster cut gets you through rougher passes quicker, and longer life helps keep the abrasive working instead of glazing over early.

The delta shape is the whole point for detail work. It gets into corners, along narrow rails, and into the kind of tight spots where a round pad just leaves work behind. Combined with Festool StickFix backing, these sheets are easy to change when you are stepping through grit stages or replacing a worn sheet mid-job.

Compatibility is straightforward. These sheets are suitable for the Festool DTS 400, DTSC 400, and DS 400 sanders. If that is the platform you already use, this pack keeps you in the proper fitment without guessing at pad match or hole layout.

Bottom line: this is a smart buy for woodworkers, carpenters, painters, and finish trades who need a wood-focused abrasive in a corner-friendly format. If your work involves sanding profiles, trim parts, furniture components, or other detailed wood surfaces, the Festool STF DELTA/9 P80 RU2/50 Rubin 2 sanding sheets make a lot more sense than trying to force a one-size-fits-all abrasive into finish work.
