Norton 66254487442 Psa Disc 220 Grit 5 Inches 100 Pack

Product Description

The NORTON 66254487442 is a pressure-sensitive adhesive (PSA) abrasive disc designed for fine surface finishing and prep work. Measuring 5 inches in diameter, each disc is coated with silicon carbide abrasive at 220 grit, placing it in the very fine grade range. The B-weight paper backing provides a balance of flexibility and stability, making it well-suited for contour sanding and flat stock work. Sold in a roll of 100 discs, this product belongs to the A413 series. Licensed tradespeople and shop technicians rely on this type of disc for consistent cut rate and predictable finish quality across a range of substrate materials.

These PSA discs are used in automotive body prep, woodworking, metal finishing, and light fabrication environments. The 220 grit rating is appropriate for finish sanding between coats, surface smoothing before final treatment, or removing minor surface imperfections. The flexible paper backing allows the disc to conform to slightly curved or uneven surfaces. No vacuum holes are included, making this disc compatible with solid backup pads rather than dust-collection sanding systems. The gray silicon carbide grain is well-suited to harder, brittle materials including stone, glass, ceramics, and certain non-ferrous metals, in addition to general-purpose finishing applications.

Installation Notes

PSA discs are installed by peeling the liner from the adhesive backing and pressing firmly onto a clean, dry backup pad. Ensure the backup pad is free of debris or residual adhesive before mounting a new disc to achieve full contact and even wear. Disc replacement should be performed with the tool powered off and disconnected from its power source. Follow applicable workplace safety standards when working with abrasives, including eye and respiratory protection.
