3M 7010362337 Psa Disc 120 Grit 5 Inches 125 Pack

Product Description

The 3M 7010362337 is a pressure-sensitive adhesive (PSA) abrasive disc designed for use with random orbital sanders in surface preparation, finishing, and material removal applications. Each disc measures 5 inches in diameter and cuts with 120-grit silicon carbide abrasive, placing it in the fine grade range. The paper backing is A-weight, which provides flexibility for contouring and detail work. Five vacuum holes are integrated into each disc to support dust extraction during use. This item ships as a pack of 125 discs. It is a go-to consumable for HVAC sheet metal prep, plumbing surface conditioning, and general trade finishing work.

These PSA discs are suited for both residential and light commercial applications where a fine finish pass is needed before sealing, priming, or assembly. The pressure-sensitive adhesive backing mounts directly to PSA-compatible random orbital sander pads without the need for hook-and-loop hardware. The silicon carbide abrasive cuts consistently on metal, plastic, and composite surfaces. The gray discs from the 426U series are commonly used by HVAC fabricators, pipefitters, and general contractors for deburring and surface prep tasks.

Installation Notes

These discs are installed by a tradesperson or technician by pressing the adhesive side firmly onto a clean, dry PSA sander pad. Ensure the backing pad surface is free of debris before mounting to achieve a secure bond. Do not use on a spinning sander until the disc is fully seated and centered. Spent discs should be removed carefully to avoid tearing the backing pad surface.
