3M 7000118108 Psa Abrasive Disc 80 Grit 5 in 125 Pack

Product Description

The 3M 7000118108 is a pressure-sensitive adhesive (PSA) abrasive disc designed for use with random orbital sanders in sanding and surface preparation applications. Each disc measures 5 inches in diameter and cuts with 80-grit aluminum oxide abrasive, placing it in the medium grade range. The gold-colored paper backing is A-weight, offering a balance of flexibility and support suited to contoured and flat surfaces. Five vacuum holes are included for dust extraction. This disc is sold in a package of 125 and is a common consumable for HVAC sheet metal prep, finish carpentry, and light metal fabrication work.

This disc is suited for residential and light commercial surface preparation tasks where a medium grit cut is needed before finishing or coating. The PSA mount allows fast disc changes on compatible random orbital sanders without tools. The flexible paper backing conforms to mild surface irregularities, making it useful for both flat panel work and slightly contoured substrates. HVAC technicians, plumbers, and general contractors commonly use this grit range for deburring, rust removal, and weld blending on metal surfaces.

Installation Notes

Installation of PSA discs requires a clean, dry sander backing pad free of debris or adhesive residue from previous discs. Ensure the sander is powered off and disconnected before changing discs. Press the disc firmly and evenly onto the backing pad to ensure full adhesive contact and prevent edge lifting during operation. Follow applicable shop safety practices including eye and respiratory protection when sanding metal or coated surfaces.
