Norton 66261139379 Sanding Sheet 1500 Grit Silicon Carbide

Product Description

The NORTON 66261139379 is a 1500-grit silicon carbide sanding sheet designed for ultra-fine finishing work on a wide range of surfaces. Part of the Series T401 line, this sheet uses a closed-coat construction on a B-weight paper backing, delivering consistent abrasive contact and smooth material removal at very fine grits. The silicon carbide mineral cuts aggressively relative to its grit rating, making it well-suited for final-pass sanding, polishing prep, and surface refinement on metal, lacquer, primer, and composites. The sheet is rated for both wet and dry use, which gives the technician flexibility depending on the application and finish requirements.

This sanding sheet is used in finishing and surface prep operations across automotive refinishing, metal fabrication, woodworking, and industrial maintenance. The ultra-fine 1500-grit rating positions it at the final stages of a sanding sequence, just before compounding or polishing. Wet sanding applications benefit from the waterproof construction, allowing water or lubricant to be used to float away swarf and reduce heat buildup during finishing. It is suitable for hand sanding blocks or compatible sheet sanding tools.

Installation Notes

This abrasive sheet is installed by trade professionals and skilled technicians performing surface finishing work. Secure the sheet firmly to the sanding block or tool before use to prevent slippage. When wet sanding, ensure the work area has adequate drainage and that any electrical equipment nearby is kept clear of water. Follow applicable shop safety standards for eye protection and dust control when sanding dry.
