Festool Granat P400 6-in Abrasive Sanding Discs 50-Pack - Durable

In this review the Festool 578365 Granat P400 6-in abrasive discs are examined for professional finishers and serious DIYers who need consistent, clog-resistant sanding for modern paint systems and VOC clear coats. The bottom line: the discs deliver reliable, long-lasting abrasion and resist smearing on high-VOC and scratch-resistant coatings, making them a sensible choice when surface quality and reduced rework matter most.

Key Features

• Compatibility: Fits a wide range of 6-in sanders such as RO 150, ETS 150 and LEX 150, so it integrates easily into existing Festool tool setups.
• Premium abrasive mix: Hardened Aluminum Oxide and Ceramic Grit provide aggressive but controlled material removal suited to both stock removal and finish sanding.
• Multi-Jetstream 2: The high-tech coating and perforation pattern reduce clogging and temperature buildup for longer usable life on each disc.
• Paint and clear coat handling: Recommended for VOC clear coats and modern paint systems, minimizing smearing and uneven sanding on sensitive surfaces.
• Material versatility: Effective on plastics, mineral materials, acrylics, repair compounds and fillers, allowing one grit to serve multiple repair and refinishing tasks.

Who It's For

These 6-in P400 discs are aimed at body shop technicians, cabinetmakers and furniture refinishers who need a mid-fine abrasive for preparing clear coats, smoothing primers and blending repairs. The grit level and construction suit users who want fewer disc changes and consistent results across mixed substrates.

Those working only on coarse stock removal or who require ultra-fine polishing beyond P1500 should consider other grits in the Granat range; likewise, buyers without a compatible 6-in sander may find these discs incompatible with their tools.

Pros & Cons

Pros

• High resistance to clogging and smearing, which extends life and reduces rework.
• Durable composition that performs well on solid surface materials and wood finishes.
• Designed for modern paint systems and VOC clear coats, improving finish consistency.

Cons

• Higher cost per disc noted by some customers, so value depends on frequency of use and the saving from reduced rework.
