Norton 66254421221 Paper Hook Loop Disc 5in No Hole P600B

Product Description

The NORTON 66254421221 is a 5-inch hook and loop abrasive paper disc designed for fine finishing work on bare or coated surfaces. Manufactured under the A475 series, this disc uses P600B grit — a fine abrasive grade suited for final sanding passes, scuff sanding between finish coats, and surface preparation before priming or sealing. The hook and loop backing allows fast disc changes without adhesive residue, reducing downtime in high-volume sanding applications. Each pack contains 100 discs, with a case quantity of 400, making it practical for shop or fleet restocking. Sold by the each unit of measure.

This disc is used in automotive body finishing, woodworking shops, and light metal surface preparation where a consistent fine scratch pattern is required before topcoat application. The no-hole design suits sanders without integrated dust collection ports, or applications where dust extraction is managed externally. It is a common choice for body shop technicians, finish carpenters, and industrial painters working on flat or low-contour surfaces requiring controlled material removal at fine grit.

Key Features

• P600B fine grit for final finishing and between-coat scuff sanding
• 5-inch diameter with no hole — compatible with solid-face hook and loop backup pads
• Hook and loop backing for tool-free disc swaps and consistent repositioning
• A475 series paper construction for controlled cut rate at fine grit levels
• Sold in packs of 100 with a case quantity of 400 for efficient restocking

Compatibility

Designed for use with 5-inch hook and loop backup pads on random orbital and rotary sanders that accept solid-face 5-inch discs with no center hole.

Installation Notes

Attach the disc to a clean, dry 5-inch hook and loop backup pad — ensure the pad surface is free of debris that would prevent full contact. Align the disc flat against the pad before applying pressure to the workpiece. Inspect discs before use and discard any that show tears, loading, or loss of abrasive grain. Follow applicable shop safety standards including eye and respiratory protection when sanding.
