3M 7010326148 Psa Abrasive Disc 120 Grit 5 Inches 100 Pack

Product Description

The 3M 7010326148 is a pressure-sensitive adhesive (PSA) abrasive disc designed for material removal and surface finishing in trade and industrial settings. Each disc measures 5 inches in diameter and cuts with 120-grit aluminum oxide abrasive, placing it in the fine-grade range for controlled stock removal and surface prep. The X-weight cloth backing provides durability and flexibility, allowing the disc to conform to surfaces without tearing under load. Licensed trades and shop technicians use these discs on bench top motors and random orbital sanders where a secure, peel-and-stick mount is preferred over hook-and-loop fastening. Sold in a pack of 100 discs.

These PSA discs are suited for metal fabrication, woodworking, and general surface preparation tasks in both shop and field environments. The aluminum oxide abrasive grain performs reliably across ferrous and non-ferrous metals as well as wood substrates. The 120-grit designation makes this disc appropriate for intermediate finishing passes where scratches from coarser grits need to be refined before final finishing steps. The flexible cloth backing allows use on contoured and flat surfaces without sacrificing disc integrity during extended runs.

Installation Notes

PSA discs are installed by peeling the liner and pressing the adhesive side firmly onto a clean, dry backing pad rated for 5-inch discs. Verify the sander or bench motor is powered off and unplugged before changing discs. Ensure the backing pad surface is free of debris or adhesive buildup that could cause uneven seating. Discs should be stored flat and at room temperature to maintain adhesive integrity before use.
