Norton 66261101155 Sanding Sheet 150 Grit Silicon Carbide

Product Description

The NORTON 66261101155 is a silicon carbide sanding sheet rated at 150 grit, classified as Very Fine grade. It belongs to the T461 series and uses a C-weight paper backing with a closed coat density. The sheet supports both dry and wet sanding applications, making it versatile across a range of surface preparation tasks. It is waterproof, allowing use with water or other cutting fluids when wet sanding is required. Finishing technicians, woodworkers, metalworkers, and auto body professionals commonly use this sheet for fine surface preparation and finishing work.

This sanding sheet is suited for fine finishing passes on wood, metal, plastic, and painted surfaces. The silicon carbide abrasive cuts quickly and consistently, making it appropriate for smoothing between coats of finish, light metal polishing, and surface conditioning. The closed coat construction delivers more abrasive per square inch, which supports consistent scratch patterns and uniform material removal on harder substrates. It is designed for bench-top sanding, hand sanding blocks, and compatible orbital or finishing sanders.

Installation Notes

This sheet is installed by finishing technicians and general tradespeople as part of surface preparation and finishing workflows.

When wet sanding, ensure the workpiece and surrounding area are properly prepared for water exposure. Inspect the sheet regularly during use and replace when abrasive loading or wear reduces cutting efficiency.
