Festool Granat Sanding Sheet 80x133mm 150 Grit 100-Pack

The 80x133mm form factor is what makes this pack of 100 Granat sheets worth considering for finish work. Most sanders use round discs. This narrow rectangular profile gives you the edge control that matters when working modern VOC finishes.

Rectangular Design and Modern Coating Performance

Festool engineered these sheets specifically for VOC clear coats and scratch-resistant coatings. The shape isn’t arbitrary. At 80mm x 133mm, you get superior control for edge and frame sanding — the detailed work where round sanders struggle. Try getting consistent pressure along a cabinet frame edge with a 5-inch disc. You can’t.

The abrasive itself uses hardened aluminum oxide and ceramic grit. That ceramic component matters. Standard aluminum oxide loads up on modern finishes. The ceramic grit keeps cutting through VOC clear coats where lesser abrasives clog and glaze.

Dust Management and Compatibility

The Multi-Jetstream hole pattern handles dust extraction better than standard patterns. This isn’t marketing fluff. Modern coatings generate fine dust that clogs standard extraction holes. The Jetstream pattern keeps channels clear longer.

StickFix backing means quick changes without alignment hassles. Simply align the holes with your sander’s pad and press firmly. No more fiddling with PSA sheets that tear when you remove them.

Compatible sanders include:

• Festool RTS 400
• Festool RTSC 400
• Festool RS 400
• Festool RS 4
• Festool LS 130
• Festool HSK-A 80x130
• Festool HSK 80x133

Granat outperforms Rubin 2 on VOC finishes and hard sublayers. Saphir strips aggressively, but Granat handles surface prep and finishing. The P150 grit sits in that sweet spot for pre-finish sanding — fine enough to eliminate scratches but coarse enough to provide tooth for topcoats.

Verdict

Users rate these sheets 5/5 stars for durability and clog resistance. The higher pack price pays off in extended life. For cabinet makers and finish carpenters working modern coatings, the rectangular profile and ceramic grit composition deliver measurable advantages over round discs and standard abrasives.

Skip these if you’re just knocking down drywall compound. That’s overkill. But for precision edge work on VOC finishes, the specialized design handles repair compound, filler, varnish, and modern paint systems better than general-purpose sheets.

The 100-pack quantity makes sense for production shops. Festool’s warranty covers defects but not wear — these are consumables. At P150 grit with ceramic content, expect consistent performance through the entire pack.

Frequently Asked Questions

What makes the 80x133mm size better than standard round discs?

The narrow rectangular profile provides superior control for edge and frame sanding. Round discs wobble on edges. This shape maintains flat contact along cabinet frames, door edges, and architectural millwork where precision matters.

How does the Multi-Jetstream pattern improve dust extraction?

The Multi-Jetstream hole pattern provides superior dust extraction compared to standard patterns. Multiple extraction channels prevent the fine dust from modern coatings from clogging single holes. Better extraction means longer abrasive life and cleaner work surfaces.

Will these sheets work with non-Festool sanders?

These sheets are designed for Festool sanders including the RTS 400, RTSC 400, RS 400, RS 4, LS 130, and HSK models. The 80x133mm size and hole pattern are Festool-specific. They won’t properly fit other brands’ rectangular sanders.

What’s the difference between Granat and other Festool abrasives?

Granat is Festool’s all-round performer, preferred for modern VOC finishes and hard sublayers over the wood-specific Rubin 2. Saphir focuses on extreme material removal, while Granat optimizes for surface preparation and finishing coatings.
