Norton 66261139383 Sanding Sheet 600 Grit Aluminum Oxide

Product Description

The NORTON 66261139383 is a 600-grit aluminum oxide sanding sheet designed for extra fine finishing work across a broad range of surfaces. It belongs to the T247 series and features a B-weight paper backing, which provides a balance of flexibility and support suited to hand sanding and finish passes. The closed-coat construction places abrasive grains tightly together, delivering consistent scratch patterns and efficient material removal at fine grit levels. This sheet supports both dry and wet sanding applications, making it practical for tasks where water or lubricant is used to reduce heat and loading on the workpiece.

The 66261139383 is used in trade and production environments where a fine, controlled finish is required before final coating, sealing, or polishing. Typical applications include surface preparation on wood, metal, and composites in carpentry, auto body, plumbing fixture refinishing, and general maintenance work. The waterproof construction allows use with water-based lubricants, extending sheet life during wet sanding operations. It is sold individually, with a minimum order quantity of 50 sheets.

Installation Notes

Sanding sheets are installed by trade professionals and skilled DIYers using hand sanding blocks or pad holders. Secure the sheet firmly to the backing block before use to prevent slipping. When wet sanding, ensure the work surface and surrounding area are safe for water contact and follow applicable shop safety practices. Inspect sheets before use and replace when abrasive grain is worn or the backing shows tears.
