Festool Multijet 2 Disc 6″ 320 Grit 100-Pack

Worth it for contractors who need sanding discs that’ll last 5-10 times longer than standard aluminum oxide. The Multi-Jetstream 2 system with its 48-hole pattern delivers virtually 100% dust extraction — game-changing if you’re tired of clouds of dust filling the shop or client’s home. At P320 grit, this disc sits firmly in the finish sanding category, specifically optimized for VOC clear coats where other abrasives fail or gum up quickly.

Skip it if you’re just knocking down rough surfaces or working with traditional finishes. This is specialist gear for modern coating systems, and you need compatible Festool sanders to make the technology work.

The Multi-Jetstream 2 Advantage

The 48-hole pattern creates intake and exhaust channels for virtually 100% dust removal. That’s not marketing fluff — the disc actively moves air through the abrasive surface, pulling dust away before it can clog the grit or float into your lungs.

Hardened Aluminum Oxide and Ceramic Grit composition gives these discs their durability edge. The stearate coating prevents loading and extends disc life — critical when you’re sanding modern VOC finishes that turn standard discs into expensive coasters after a few passes.

Specification	Value
Diameter	6 inches (150 mm)
Grit Rating	P320
Hole Pattern	Multi-Jetstream 2 (48 holes)
Abrasive Material	Hardened Aluminum Oxide and Ceramic Grit
Backing	Paper with StickFix hook-and-loop system
Coating	Stearate (oil) coating for heat and clog resistance
Quantity	100 discs per pack

Here’s what matters: the anti-clogging design with open-coat structure and stearate coating prevent loading and extend disc life. You get rapid material removal capacity without burning the surface. That combination — aggressive cutting with finish-quality results — justifies the premium positioning.

Real-World Performance

Testing shows 5-10x longer lifespan compared to standard aluminum oxide discs. Multi-Jetstream 2 pattern offers superior dust extraction (virtually 100%) compared to standard 8-hole or 17-hole patterns. Those aren’t small improvements — they’re the difference between changing discs every few minutes versus getting through entire projects on a single disc.

Reviews average 4.6 stars across 12 ratings. Contractors highlight excellent finish quality, consistent grit performance, efficient dust extraction, and easy mounting. The only complaint: limited availability at some retailers.

Applications where these discs excel:

• Modern paint systems (VOC clear coats)
• Processing hard sublayers (primers and fillers)
• Sanding plastics, mineral materials, and acrylics
• Repair compounds and fillers
• General wood finishing, furniture, and cabinet making
• Automotive and marine finishing

Compatibility Requirements

Compatible sanders include ETS 150, ETS EC 150, RO 150 (Rotex), Shinex 150, and LEX 150. You must use a Multi-Jetstream 2 backing pad (e.g., STF D150/48) — standard backing pads won’t align with the 48-hole pattern.

Installation takes seconds: Align the 48-hole pattern of the disc with the corresponding holes on the backing pad. Press the disc firmly onto the hook-and-loop surface (StickFix). Use light to moderate pressure during operation; replace once the grit is noticeably dull.

The 3-year all-inclusive warranty requires registration within 30 days of purchase. Sanding discs are consumables and typically do not carry a wear-and-tear warranty, but are covered by retailer-specific return policies (e.g., 30-day money-back guarantee). Theft protection is included in the 3-year all-inclusive package for registered tools.

FAQ

Do these discs really last 5-10 times longer than standard discs? Yes — the hardened aluminum oxide and ceramic grit composition combined with the stearate anti-clogging coating delivers 5-10x longer lifespan compared to standard aluminum oxide discs. The difference is most dramatic when sanding modern VOC finishes that quickly clog standard abrasives.

Can these discs work with any 6-inch random orbital sander? No — these discs are specifically designed for Festool sanders including ETS 150, ETS EC 150, RO 150 (Rotex), Shinex 150, and LEX 150. You also need a Multi-Jetstream 2 backing pad (e.g., STF D150/48) to align with the 48-hole pattern. Standard backing pads won’t work.

What makes P320 grit special for VOC clear coats? This product is specifically optimized for VOC clear coats where other abrasives fail or gum up quickly. The stearate coating prevents the heat buildup and loading that ruins standard discs when sanding modern paint systems. P320 provides the fine finish these coatings require without burning through.

Is the dust extraction really that much better? The 48-hole Multi-Jetstream 2 pattern delivers virtually 100% dust extraction compared to standard 8-hole or 17-hole patterns. The difference is immediately obvious — cleaner work environment, better visibility of your work surface, and significantly less cleanup time.
