3M 7000118916 Psa Disc 1 in 120 Grit Aluminum Oxide

Product Description

The 3M 7000118916 is a pressure-sensitive adhesive (PSA) abrasive disc designed for precision surface finishing in trade and industrial applications. Measuring 1 inch in diameter, this disc features 120-grit aluminum oxide abrasive on an X-weight cloth backing, delivering consistent fine-grade material removal on metal, wood, and composite surfaces. The flexible construction conforms to contoured workpieces, making it well suited for detail sanding and finishing work. HVAC technicians, pipefitters, and metalworkers commonly use discs like this for deburring, surface prep, and weld blending on tight or curved surfaces.

This PSA disc fits benchtop motors and random orbital sanders that accept 1-inch PSA-style abrasive discs. The pressure-sensitive adhesive backing allows for quick disc changes without mechanical fasteners, reducing downtime during high-volume finishing work. The Series 348D disc is sold individually with a minimum order quantity of 50 units, making it appropriate for shops or service fleets maintaining consistent inventory of consumable abrasives. No vacuum holes are included, so it is best matched to sanders that do not require dust-extraction ports at this disc size.

Key Features

• 120-grit aluminum oxide abrasive for fine-grade material removal and surface finishing

Compatibility

Compatible with benchtop motors and random orbital sanders that accept 1-inch PSA-style abrasive discs without vacuum holes.

Installation Notes

Clean the sander's backup pad thoroughly before applying the PSA disc to ensure full adhesive contact and prevent disc slippage during operation. Peel the release liner and press the disc firmly and evenly onto the pad before powering the tool. Inspect the disc before each use and replace it if the abrasive shows glazing, loading, or backing tears. Dispose of used abrasive discs in accordance with local shop waste regulations.
