Norton 66261181509 Sanding Sheet 400 Grit Aluminum Oxide

Product Description

The NORTON 66261181509 is a 400-grit aluminum oxide coated sanding sheet designed for super fine surface finishing work. Built on a J-weight cloth backing, it delivers flexibility without sacrificing durability, making it well suited for contoured surfaces and hand-sanding applications. The closed coat construction keeps abrasive grain tightly packed across the surface for consistent scratch patterns and efficient material removal at this fine grit range. Dry use only, this sheet is not waterproof. It is load resistant, reducing clogging when sanding softer materials or finishes.

This sanding sheet is used in light stock removal, finish sanding, and surface prep work across woodworking, metalworking, and general fabrication trades. The 400-grit super fine grade makes it appropriate for final passes before coating, sealing, or polishing. J-weight cloth backing provides the flexibility needed for working curved or irregular surfaces. Suitable for professional finishing contractors, cabinet shops, and maintenance trades requiring consistent fine-grit abrasive performance on dry surfaces.

Installation Notes

Sanding sheets are installed by finishing contractors, woodworkers, and general tradespeople using hand blocks, pad sanders, or orbital finishing tools. Ensure the sheet is properly seated and secured before use to prevent slippage. Inspect the sheet regularly during use and replace when grit becomes worn or the backing shows signs of tearing. Do not use this sheet in wet or waterproof applications.
