Norton 662611-31498 Sanding Disc 5 Inch P80B Grit A275

Product Description

The NORTON 662611-31498 is a pressure-sensitive adhesive (PSA) sanding disc designed for use with 5-inch random orbital and DA sanders equipped with vacuum dust extraction. Part of the A275 line, these discs feature a P80B grit aluminum oxide abrasive coating suited for aggressive material removal on bare wood, painted surfaces, body filler, and primers. The 5-hole vacuum pattern allows dust to pass through the disc and into the sander's dust collection system, keeping the work surface clear and extending abrasive life. Sold in bulk rolls of 100 discs per unit of measure, these are a high-volume consumable for production finishing environments.

These discs are used in automotive body shops, woodworking shops, and general surface preparation work where consistent stock removal at P80B grit is required. The PSA backing sticks directly to hook-and-loop or foam backup pads that accept self-adhesive discs. The 5-inch diameter fits standard 5-inch PSA backup pads. Bulk packaging at 100 discs per order quantity makes this product suitable for shops with high daily sanding volume that need to minimize restocking frequency.

Key Features

• A275 aluminum oxide abrasive construction for consistent, aggressive stock removal
• P80B grit designation — coarse cut suitable for shaping, leveling, and heavy scratch removal
• 5-hole vacuum pattern channels dust away from the cutting surface to maintain abrasive efficiency
• Pressure-sensitive adhesive backing for direct attachment to compatible PSA backup pads
• 5-inch diameter fits standard 5-inch random orbital and DA sander backup pads
• Bulk roll format with minimum order quantity of 100 discs reduces per-unit cost for production use

Compatibility

Designed for use with 5-inch PSA backup pads on random orbital and dual-action sanders with 5-hole vacuum dust extraction systems.

Installation Notes

Ensure the backup pad is clean and free of debris before applying each disc — contamination under the PSA backing reduces adhesion and can cause disc slippage during use. Power down and unplug the sander before changing discs. Peel the disc from the backing and press firmly onto the pad, aligning vacuum holes before applying pressure. Discard discs when abrasive loading or glazing reduces cutting efficiency rather than continuing to use a spent disc.
