Norton 66254487399 Sanding Sheet 240 Grit Silicon Carbide

Product Description

The NORTON 66254487399 is a 240-grit silicon carbide sanding sheet designed for dry abrasive finishing applications. Rated Very Fine grade, it uses an open-coat density that reduces loading and extends sheet life during finish sanding passes. The B-weight paper backing provides a balance of flexibility and durability suited to hand sanding blocks and orbital finishing work. This sheet is part of the Series A413 line and is a standard consumable stocked and used by finishing contractors, cabinet shops, and trade professionals who require consistent cut on wood, composites, and similar substrates.

This sanding sheet is intended for dry sanding applications only. The open-coat construction and silicon carbide abrasive make it well suited for final finishing stages where a smooth, consistent surface is required. Typical use cases include furniture finishing, surface prep before painting or staining, and light material removal on wood and synthetic surfaces. It is not rated for wet or wet-dry use.

Installation Notes

Sanding sheets are installed and replaced by finishing contractors, woodworkers, and trade professionals as a routine consumable. Ensure the sheet is seated flat against the backing pad or sanding block before use to prevent uneven wear or tearing. Inspect the sheet regularly during use and replace when abrasive loading or glazing reduces cut performance. This sheet is not rated for wet use — do not use with water, solvents, or lubricants.
