Norton 66261100940 Sanding Sheet 180 Grit Silicon Carbide

Product Description

The NORTON 66261100940 is a silicon carbide abrasive sanding sheet rated at 180 grit, falling in the very fine grade range. Designed for both wet and dry sanding applications, it features a cloth backing with a closed coat density for consistent material removal across the sheet surface. The Q421 series construction makes this sheet a reliable choice for surface finishing, deburring, and prep work on metals, composites, and other hard materials. Licensed tradespeople and shop technicians working in fabrication, automotive, or general metalworking will find this sheet suited to fine surface conditioning tasks.

This sanding sheet is intended for use in hand sanding or backing-plate applications where very fine material removal and surface refinement are required. Its wet and dry capability allows for use with water or lubricants to reduce loading and improve finish quality on harder substrate materials. Closed coat construction provides maximum abrasive coverage for efficient cutting action on smooth or semi-finished surfaces.

Key Features

• 180 grit, very fine grade silicon carbide abrasive for controlled material removal
• Cloth backing provides flexibility and durability during use
• Closed coat density maximizes abrasive surface coverage
• Compatible with both wet and dry sanding applications
• Waterproof construction supports use with water or cutting fluids
• Q421 series design for consistent finish results

Compatibility

Designed as an OEM-style abrasive sheet for hand sanding or machine-backed applications requiring very fine grit silicon carbide cutting action on metal, composite, or similar hard surfaces.

Installation Notes

Sanding sheets should be installed on a clean, flat backing block or appropriate holder before use. Power down any motorized equipment and secure the workpiece before beginning surface work. Follow applicable shop safety practices, including use of appropriate respiratory protection when dry sanding materials that generate fine particulate. When using wet, ensure the work area and any electrical equipment are properly isolated from moisture.
