The NORTON 66254480232 is a 5-inch diameter, no-hole paper hook-and-loop abrasive disc designed for fine finishing work in automotive, woodworking, and surface prep applications. Graded at P800B on the A975 abrasive series, this disc delivers consistent scratch patterns and controlled material removal at the fine end of the grit spectrum. It mounts to hook-and-loop backup pads without fasteners, making disc changes fast during production runs. Sold in packs of 50, it is suited for body shops, cabinet shops, and finishing contractors who cycle through fine-grit media regularly.
This disc is used in applications where surface finish quality is critical before priming, sealing, or topcoat. The P800B grit rating makes it appropriate for final sanding passes on wood, painted surfaces, or body filler. The no-hole design suits backup pads that use solid face hook-and-loop attachment rather than vacuum extraction systems. The A975 designation identifies the abrasive line within the Norton portfolio, indicating a paper-backed construction engineered for consistency across the sheet.
Designed for use with 5-inch solid-face hook-and-loop random orbital or rotary backup pads. No-hole configuration is not compatible with dust-extraction pads requiring vacuum ports.
These discs are installed by hand by pressing the loop face firmly onto a hook-face backup pad mounted to a random orbital or rotary sander. Ensure the backup pad is clean and free of debris before attaching a new disc to maintain full contact and prevent premature release. Operate at the RPM rating specified for the sander and backup pad in use. Inspect discs for loading or glazing and replace when cut rate declines noticeably.
