Norton 66261100945 Sanding Sheet 150 Grit Silicon Carbide

Product Description

The NORTON 66261100945 is a silicon carbide abrasive sanding sheet rated at 150 grit for fine-grade material removal. It features a cloth backing with a closed coat density, making it suitable for both dry and wet sanding applications. Part of the Q421 series, this sheet is designed for use on metals, composites, ceramics, stone, and other hard or dense substrates where silicon carbide abrasive excels. Tradespeople, fabricators, and finishing technicians use this sheet for surface prep, deburring, and fine stock removal in production or field environments.

This sanding sheet is appropriate for hand sanding blocks, orbital sanders, or flat-bed finishing equipment in metal fabrication shops, manufacturing facilities, and maintenance environments. The closed coat construction delivers consistent scratch patterns suited to fine finishing stages. Wet or dry capability allows use with water or light cutting fluids to reduce heat buildup and extend abrasive life on sensitive surfaces.

Key Features

• 150 grit silicon carbide abrasive for fine-grade cutting action on hard materials
• Cloth backing provides flexibility and durability under load
• Closed coat density maximizes abrasive coverage for consistent finish
• Wet or dry rated — compatible with water and light cutting fluids
• Q421 series construction for uniform performance across production runs

Compatibility

Designed as an OEM-style abrasive replacement for standard sanding sheet applications on sanders and finishing equipment that accept flat sheet abrasives.

Installation Notes

This sheet is installed by fabricators, machinists, and finishing technicians on compatible hand blocks or power sanders. Ensure the sanding surface and backing plate are clean and free of debris before mounting the sheet to maintain flat contact. When using wet, verify that associated equipment is rated for wet operation before introducing fluids. Inspect the sheet before each use and replace when abrasive loading or wear reduces cutting efficiency.
