Norton 66261139388 Sanding Sheet 240 Grit Aluminum Oxide

Product Description

The NORTON 66261139388 is a coated abrasive sanding sheet designed for fine surface finishing on wood, metal, and composites. Built on a B-weight paper backing with an open-coat aluminum oxide abrasive layer, this sheet delivers consistent material removal at 240 grit without loading quickly on softer substrates. The open-coat construction allows dust and debris to clear away from the abrasive surface during use, extending sheet life. Rated for both dry and wet sanding applications, it fits into general prep and finishing workflows across multiple trades and surface types.

This sanding sheet is suited for finish sanding passes where surface smoothness is the goal rather than aggressive stock removal. At 240 grit, it works well for scuff-sanding primer, final sanding between coats of finish, and light deburring of metal edges. It measures 9.29 inches wide by 11.34 inches long, fitting standard hand blocks and many orbital finishing tools. The Series T214 designation identifies the product line within the NORTON coated abrasives catalog. Wet sanding capability makes it useful in automotive, cabinet, and light metalworking applications.

Installation Notes

Secure the sheet firmly to the sanding block or tool pad before use to prevent slipping. For wet sanding, allow the sheet to soak briefly before applying to the workpiece. Inspect the abrasive surface periodically and replace when cutting action diminishes noticeably. Dispose of used sheets according to local regulations when wet-sanding with finish or primer materials.
