Norton 66254487448 Psa Disc 6 Inch 180 Grit 100 Pack

Product Description

The NORTON 66254487448 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for fine surface finishing and material preparation. Built on a lightweight B-weight paper backing, each disc carries 180-grit silicon carbide abrasive — a very fine grade suited for smoothing, refining surfaces, and removing light scratches between finishing stages. The 6-inch diameter fits standard PSA-style random orbital and DA sanders common across metalworking, woodworking, automotive body, and composite fabrication shops. This listing covers a pack of 100 discs from the Norton A413 series.

These discs are intended for applications requiring consistent, fine abrasion across flat and semi-contoured surfaces. Silicon carbide abrasive cuts hard and brittle materials efficiently, making this disc a practical choice for finish sanding bare metal, painted surfaces, lacquers, primers, and hardwoods. The flexible paper backing conforms slightly to workpiece contours. No vacuum holes are included, so these are suited for solid-platen or non-vac PSA backing pads. Typical users include fabricators, finishing technicians, auto body specialists, and general shop trades.

Key Features

• 180-grit silicon carbide abrasive for very fine finishing and between-coat sanding
• B-weight paper backing provides flexibility for light contouring work

• 100 discs per pack for extended production use

Compatibility

Designed for use with 6-inch PSA (pressure-sensitive adhesive) backing pads on random orbital, DA, or disc sanders without vacuum hole requirements. No specific compatible equipment model numbers were provided in the product data.

Installation Notes

Mount discs to a clean, dry 6-inch PSA backing pad — oil, dust, or worn pad surfaces will reduce adhesion and cause disc slippage. Ensure the sander is powered off and disconnected before changing discs. Follow shop safety practices including appropriate respiratory protection when dry-sanding materials that generate fine particulate. Discard discs showing loading, tearing, or loss of abrasive coverage.
