Norton 66261131488 Psa Disc 400 Grit 5 Inches 100 Discs

Product Description

The NORTON 66261131488 is a pressure-sensitive adhesive (PSA) abrasive disc designed for fine surface finishing and prep work. Built on a lightweight B-weight paper backing with an aluminum oxide abrasive grain, this disc delivers consistent stock removal at a 400 super fine grit rating. The flexible backing conforms to slightly contoured surfaces, making it suitable for finish sanding on wood, metal, and composite materials. Each pack contains 100 discs sized at 5 inches in diameter. The disc includes 5 vacuum holes for dust extraction compatibility, keeping the work surface clear and extending disc life.

This disc is used in residential and light commercial finishing applications including furniture, cabinetry, auto body prep, and general metalwork. The PSA mount allows quick disc changes on compatible 5-inch random orbital and disc sanders equipped with a hook-and-loop or PSA platen. The super fine 400 grit rating makes it appropriate for final sanding passes before finishing, sealing, or coating. Tradespeople in woodworking, flooring, and light fabrication shops will find this disc well suited to high-volume sanding tasks where consistent finish quality is required.

Installation Notes

PSA discs are installed by peeling the liner and pressing the disc firmly onto a clean, dry PSA-compatible sanding platen. Ensure the sander is powered off and unplugged before changing discs. Align vacuum holes with the platen ports to maintain dust extraction efficiency. Discs should be replaced when abrasive grain becomes glazed or loaded, as continued use reduces cut rate and surface quality.
