Norton 66254487447 Psa Disc 6 in 120 Grit Silicon Carbide 100pk

Product Description

The NORTON 66254487447 is a 6-inch PSA (pressure-sensitive adhesive) abrasive disc designed for surface preparation, finishing, and stock removal on a wide range of substrates. Built with silicon carbide abrasive on a lightweight B-weight paper backing, this fine 120-grit disc delivers consistent cut and smooth surface finish. The flexible backing conforms to slightly contoured surfaces, making it a practical choice for finishing work that demands uniformity. Each box contains 100 discs. Installation is straightforward: peel the liner and apply directly to a compatible PSA backup pad. The A413 series is a common choice among metalworkers, woodworkers, and fabricators who need reliable performance in hand-held or stationary disc sander applications.

These discs are suited for finishing metal, wood, composites, and painted surfaces. The 120-grit silicon carbide grain cuts aggressively for its grade and leaves a consistent scratch pattern, making it a logical step in a progressive sanding sequence. No vacuum holes are included, so these discs are intended for use with solid, non-perforated backup pads. Typical applications include deburring, blending welds, prepping surfaces for coating, and final shaping passes on wood or non-ferrous metal.

Key Features

• 120-grit fine grade silicon carbide abrasive for smooth, consistent surface finish
• 6-inch diameter with PSA backing for fast, tool-free pad attachment
• B-weight paper backing provides flexibility for light contouring work
• No vacuum holes — designed for use with solid backup pads
• 100 discs per box for extended production use
• Part of the NORTON A413 series

Compatibility

Designed for use with 6-inch solid PSA backup pads on disc sanders, angle grinders, and random-orbit tools that accept PSA-style abrasive discs. No vacuum-hole configuration means these discs are not compatible with dust-extraction perforated pads.

Installation Notes

Ensure the backup pad surface is clean and free of adhesive residue before applying a new disc. Peel the liner from the disc and press firmly onto the backup pad, smoothing from center outward to prevent air pockets. Power down and unplug or lock out the tool before changing discs. Discard any disc showing tears, delamination, or excessive loading.
