Norton 662611-55377 Sanding Disc 5 in A975 P400B Grit

Product Description

The NORTON 662611-55377 is a 5-inch pressure-sensitive adhesive (PSA) sanding disc designed for surface finishing and material removal in professional trade and industrial applications. Built to the A975 specification with a P400B grit rating, this disc delivers fine finishing performance suitable for paint prep, metal finishing, and composite surface work. The no-hole design provides full-face contact with the workpiece. Sold in bulk packaging of 4 units per package, these discs are intended for shops and technicians running high-volume finishing operations who need consistent abrasive performance across multiple surfaces.

This disc is well suited for automotive body work, woodworking, metal fabrication, and composite finishing where a fine P400B grit is required for final-stage surface preparation or between-coat sanding. The PSA backing allows quick mounting to compatible backup pads without the need for additional adhesives, making disc changes fast during production runs. The 5-inch diameter fits standard 5-inch PSA backup pads commonly used with random orbital and disc sanders in body shops and fabrication facilities.
