Norton 662611-23577 Psa Paper Disc 8 in 40 Grit H875 25 Pack

Product Description

The NORTON 662611-23577 is a pressure-sensitive adhesive (PSA) paper abrasive disc designed for random orbital and disc sanders used in woodworking, cabinet finishing, and surface preparation applications. Measuring 8 inches in diameter with an 8-hole vacuum pattern, this H875-type disc operates at 40 grit for aggressive stock removal and initial sanding passes. The PSA backing allows for quick, tool-free mounting to compatible foam or rubber backup pads. Licensed tradespeople and finishing contractors rely on this disc for high-volume material removal on wood, composite, and painted surfaces.

This disc is suited for residential and light commercial finishing environments where dust collection is a priority. The 8-hole vacuum pattern aligns with standard 8-inch PSA backup pads equipped for central vacuum or shop-vac dust extraction, keeping the work surface clear and extending disc life. Sold in a pack of 25, it supports sustained production runs without frequent restocking interruptions. Typical applications include door and cabinet sanding, floor prep staging, and furniture refinishing.

Installation Notes

Installation is performed by finishing professionals or experienced tradespeople. Power down and unplug the sander before mounting or removing a disc.

Do not exceed the sander manufacturer's rated RPM for the disc diameter, and replace discs that show loading, glazing, or tearing before continuing work.
