Norton 66261100960 Sanding Sheet 80 Grit Silicon Carbide

Product Description

The NORTON 66261100960 is a silicon carbide abrasive sanding sheet designed for both wet and dry material removal applications. Rated at 80 grit, this medium-grade sheet delivers consistent stock removal on hard materials such as stone, glass, ceramics, and non-ferrous metals. The cloth backing provides flexibility and tear resistance under hand or machine use. A closed coat density means abrasive grain covers the full surface area, maximizing cut rate per pass. The Q421 series designation identifies this sheet within a professional-grade line built for demanding surface preparation work.

This sanding sheet suits trade and industrial environments where controlled material removal is required on hard surfaces. Its wet and dry compatibility makes it useful for applications that benefit from water or cutting fluid to reduce heat and extend abrasive life. Typical uses include finishing stone countertops, deburring metal fabrications, and surface prep before sealing or coating. It is appropriate for use by fabricators, tile and stone installers, and general tradespeople working with hard, abrasive-resistant materials.

Compatibility

Designed for use as a general-purpose abrasive sanding sheet suitable for hand sanding blocks and compatible machine sanders accepting standard sheet dimensions. No specific equipment model compatibility was stated in the available product data.

Installation Notes

Sanding sheets should be installed on a backing pad or sanding block appropriate for the sheet size before use. When using wet, ensure that any power tool or sander is rated for wet operation before introducing water or cutting fluid. Inspect the sheet for tears or worn areas before each use and replace when cut rate diminishes noticeably. Wear appropriate eye protection and a dust mask or respirator when sanding dry, as silicon carbide dust is an inhalation hazard.
