Norton 662611-31457 Sanding Disc 5 in A275 P280B

Product Description

The NORTON 662611-31457 is a 5-inch pressure-sensitive adhesive (PSA) sanding disc designed for surface preparation and finishing work in trade and industrial settings. Built to the A275 specification, this disc features a P280B grit designation, placing it in the fine-abrasive range suited for finishing passes, paint scuffing, and light material removal. The no-hole design makes it compatible with solid backup pads where dust extraction through the disc is not required. Sold in a minimum quantity of 6 discs per order, it is well suited for shops and service professionals who maintain an ongoing supply of abrasives on hand.

This disc is used in automotive body work, metal fabrication, woodworking finish sanding, and general surface prep across light manufacturing and trade environments. The PSA backing allows quick disc changes on flat or slightly contoured backup pads. At P280B grit, it performs best as a finish or pre-finish step rather than an aggressive stock-removal application. Technicians and tradespeople working in body shops, cabinet shops, and general contracting will find this grit level appropriate for inter-coat scuffing and final surface leveling before coating or sealing.

Key Features

• A275 abrasive type construction for consistent cut and finish performance
• P280B fine grit rating suitable for finish sanding and inter-coat scuffing
• 5-inch diameter with no-hole design for use with solid PSA backup pads
• Pressure-sensitive adhesive backing for fast, secure pad attachment
• Sold in minimum quantities of 6 for ongoing shop supply management

Compatibility

Designed for use with 5-inch solid (no-hole) PSA backup pads on random orbital and disc sanders configured for adhesive-mount discs.

Installation Notes

This disc is mounted by pressing the PSA backing firmly onto a clean, dry 5-inch backup pad surface. Ensure the backup pad is free of adhesive residue or debris before applying a new disc to maintain flat, even contact. Disc changes should be performed with the sander powered off and unplugged or the air supply disconnected. Follow applicable shop safety practices including eye protection and dust control when operating any abrasive disc tool.
