Norton 66261131497 Psa Disc 5 in 100 Grit Aluminum Oxide

Product Description

The NORTON 66261131497 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface preparation, finishing, and material removal on a wide range of substrates. Part of the A275 series, this disc features 100-grit aluminum oxide abrasive at a fine grade, delivered on a B-weight paper backing. The PSA backing allows quick, secure mounting to compatible backup pads without mechanical fasteners. Five vacuum holes are integrated into the disc to support dust extraction during use, helping maintain a cleaner work surface and extending abrasive life. Each unit is sold as a roll of 100 discs.

This disc is suited for sanding operations in metal fabrication, woodworking, and general surface finishing applications. The 5-inch diameter fits standard PSA backup pads used on random orbital and disc sanders common in both shop and field environments. The flexible paper construction conforms modestly to contoured surfaces, making it a practical choice for finish passes on flat to slightly curved workpieces. Trades including metal fabricators, finishing carpenters, auto body technicians, and general maintenance professionals will find this disc appropriate for medium-to-fine finishing work.

Key Features

• 100-grit aluminum oxide abrasive for fine-grade material removal and surface finishing
• Pressure-sensitive adhesive backing for tool-free, fast disc changes on PSA backup pads
• B-weight paper backing provides flexibility for contoured and flat surface work
• 5 integrated vacuum holes support dust extraction and debris clearance
• A275 series construction for consistent cut rate and finish quality
• Pack of 100 discs per roll for extended production use

Compatibility

Designed for use with 5-inch PSA backup pads on random orbital sanders and disc sanders that support pressure-sensitive adhesive disc attachment and dust extraction through vacuum hole patterns.

Installation Notes

Installation is performed by pressing the PSA disc firmly onto a clean, dry 5-inch backup pad, ensuring full contact across the adhesive surface before operating the tool. Align vacuum holes with the backup pad port pattern to maintain effective dust extraction. Disconnect the sander from power before changing discs. Discs should be stored flat in a cool, dry environment to prevent curling or adhesive degradation prior to use.
