Norton 66261131634 Sanding Sheet 80 Grit Aluminum Oxide

Product Description

The NORTON 66261131634 is an 80-grit aluminum oxide sanding sheet designed for dry material removal in woodworking, metalworking, and general surface preparation. Classified as medium grade with a B-weight paper backing, this sheet delivers consistent cut rate on flat surfaces and is part of the Series A275 line. The open coat density reduces loading, allowing the abrasive to clear material efficiently during extended use. At 0.06 pounds per sheet, it is lightweight and sized for standard hand blocks and orbital pad sanders. This product is intended for use by professional tradespeople and skilled craftspeople who require reliable, repeatable abrasive performance.

The 66261131634 sanding sheet is suited for dry sanding applications on wood, paint, and light metal surfaces. Its open coat construction makes it particularly effective when working with soft or resinous materials that would otherwise clog a closed-coat abrasive quickly. The B-weight paper backing provides a balance of flexibility and support, making it appropriate for both hand sanding and machine sanding on flat or mildly contoured workpieces. It is not rated for wet or waterproof use and should be kept dry during storage and application.

Installation Notes

Sanding sheets are installed and replaced by the operator without specialized tools. Secure the sheet firmly to the sanding block or machine pad before use to prevent slipping. Inspect the sheet periodically during use and replace when abrasive loading or glazing reduces cutting efficiency. Store unused sheets flat in a dry environment away from moisture and extreme temperatures.
