Norton 66261131539 Hook Loop Disc 400 Grit 5 in

Product Description

The NORTON 66261131539 is a 5-inch hook and loop sanding disc designed for fine surface finishing on wood, painted surfaces, and composites. It features aluminum oxide abrasive bonded to a B-weight paper backing, delivering consistent cut and finish at 400 grit (extra fine grade). The flexible backing conforms to slightly contoured surfaces, making it suitable for hand-block sanders and random orbital sanders equipped with hook and loop pads. Installers, finish carpenters, painters, and maintenance technicians reach for this disc when prepping surfaces between coats or smoothing out imperfections before final finish application.

This disc is intended for dry sanding applications on materials such as bare wood, primer, paint, and light body filler. The coated aluminum oxide construction provides a sharp, consistent scratch pattern appropriate for finish-stage material removal. The A275 series is a general-purpose line suited to both production finishing and touchup work. No vacuum holes are present, so this disc is used on solid-pad orbital or disc sanders without dust extraction ports. Minimum order quantity is 100 discs; each unit is sold individually.

Installation Notes

Align the disc squarely over the hook and loop sanding pad before pressing firmly to seat the fastening surface. Inspect the sander pad for worn or clogged hooks before installing a fresh disc, as a degraded pad reduces holding strength and can cause disc slippage during use. Power down and unplug the sander before changing discs. Discard discs that show loading, glazing, or backing tears, as compromised abrasives produce uneven scratch patterns and can detach during operation.
