3M 7000119246 Psa Disc 220 Grit Silicon Carbide 6 Inches

Product Description

The 3M 7000119246 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface finishing and material removal in professional shop and trade environments. Built on a lightweight A-weight paper backing, this disc uses silicon carbide abrasive at 220 grit, placing it in the very fine grade range. That combination makes it well suited for finish sanding passes on wood, composites, and painted surfaces where a smooth surface is required before coating or final inspection. The disc measures 6 inches in diameter and ships in a pack of 175 discs. The flexible paper construction conforms to slightly contoured surfaces without loading quickly.

This disc is designed for use with random orbital sanders that accept 6-inch PSA-mount discs. No vacuum holes are present, making it appropriate for sanders used without dust extraction or in applications where hole patterns are not required. The gray silicon carbide abrasive is well suited for non-ferrous metals, plastics, fiberglass, wood, and finish coats. It is commonly used in cabinet shops, auto body prep, marine refinishing, and general metalworking. Series 426U is the product family designation from 3M for this line of PSA finishing discs.

Compatibility

Designed for use with 6-inch PSA-mount random orbital sanders. No specific model restrictions are stated in the product data; verify sander pad diameter and PSA-mount compatibility before ordering.

Installation Notes

Ensure the sander pad surface is clean and free of debris before applying the PSA disc, as contamination reduces adhesion and can cause the disc to release during operation. Peel the liner from the disc and press firmly onto the pad, working from the center outward. Do not exceed the sander manufacturer's rated RPM for 6-inch discs. Remove and discard discs that show signs of loading, tearing, or edge lifting to prevent surface damage.
