Norton 66261149874 Psa Disc 120 Grit Ceramic 6 Inches

Product Description

The NORTON 66261149874 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface preparation, finishing, and stock removal on a wide range of substrates. The disc measures 6 inches in diameter and features a 120-grit ceramic abrasive, classified as a fine grade. Ceramic abrasive cuts aggressively and self-sharpens under pressure, extending disc life compared to aluminum oxide alternatives. An F-weight paper backing provides flexibility for contour work while maintaining enough rigidity for flat-surface grinding. Each pack contains 100 discs.

These PSA discs are suited for metalworking, woodworking, and composite surface preparation in both shop and field environments. The pressure-sensitive adhesive backing mounts directly to a compatible PSA backup pad without fasteners or hardware, allowing fast disc changes during production runs. The H920 series is commonly used on random orbital and disc sanders in fabrication shops, cabinet shops, and general manufacturing. No vacuum holes are included, making these appropriate for solid backup pads without dust extraction ports.

Key Features

• 120-grit fine-grade ceramic abrasive for controlled stock removal and surface finishing
• Self-sharpening ceramic grain extends usable disc life under moderate to high pressure
• F-weight paper backing balances flexibility and support for flat and contoured surfaces
• PSA adhesive mount for tool-free disc changes on compatible backup pads
• No vacuum holes — suited for solid backup pad configurations
• 100 discs per pack supports high-volume production use

Compatibility

Designed for use with 6-inch PSA backup pads on random orbital sanders, disc sanders, and angle grinders configured for PSA-mount discs. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation requires a clean, dry PSA backup pad free of debris or residual adhesive from previous discs. Power down and disconnect the sander before mounting or removing any abrasive disc. Press the disc firmly and evenly onto the backup pad before resuming operation to ensure full adhesive contact. Discs should be stored flat and away from moisture to preserve adhesive integrity.
