Norton 66261139357 280 Grit Silicon Carbide Sanding Sheet

Product Description

The NORTON 66261139357 is a silicon carbide abrasive sanding sheet rated at 280 grit, classified as extra fine grade. It features a B-weight paper backing with an open coat density, making it suitable for both dry and wet sanding applications. Part of the T414 series, this sheet is waterproof, allowing use with water or other lubricants when the application calls for wet sanding. Licensed tradespeople and finishing specialists use this sheet for precision material removal and surface preparation where a controlled, fine finish is required.

This sanding sheet is intended for fine finishing work across a range of materials including wood, metal, composites, and painted surfaces. The silicon carbide abrasive cuts aggressively at fine grits, making it well-suited for final sanding passes before sealing or painting, scuffing coatings between layers, and finishing non-ferrous metals. The open coat construction reduces loading, extending usable sheet life on softer or resinous materials. It can be used dry or wet depending on substrate and finish requirements.

Key Features

• 280 grit extra fine silicon carbide abrasive for controlled fine-finish sanding
• B-weight paper backing provides flexibility and conformability to surfaces
• Open coat density reduces clogging and extends sheet life
• Waterproof construction supports both dry and wet sanding use
• Part of the T414 series for consistent abrasive performance

Compatibility

Designed as a standard sanding sheet for use with hand blocks, orbital sanders, and finishing tools that accept flat abrasive sheet stock of the corresponding dimensions.

Installation Notes

These sheets are installed by hand or mounted to a backing pad or sanding block appropriate for the substrate. Wear appropriate respiratory protection and eye protection when dry sanding. When wet sanding, ensure the workpiece and surrounding area are managed to prevent slipping hazards. Dispose of used abrasive sheets in accordance with local regulations, particularly when sanding materials that generate hazardous dust.
