3M 7000118883 Psa Abrasive Disc 120 Grit 3 Inches

Product Description

The 3M 7000118883 is a pressure-sensitive adhesive (PSA) abrasive disc designed for precision surface finishing in trade and industrial applications. Built on an X-weight cloth backing, the disc delivers the rigidity and tear resistance needed for demanding grinding and finishing tasks. The 120-grit aluminum oxide abrasive is rated Fine grade, making it well-suited for stock removal, blending, and intermediate finishing passes. At 3 inches in diameter, this disc mounts quickly to PSA-compatible platens without the need for additional fasteners. Fabricators, metalworkers, and maintenance technicians are the primary installers and users of this consumable.

This disc is compatible with benchtop motors, disc sanders, and random orbital sanders that accept 3-inch PSA-mount abrasives. The flexible cloth backing conforms to slightly contoured surfaces, making it a practical choice for both flat stock work and mild contour finishing in metal fabrication, woodworking, and general maintenance environments. No vacuum holes are included, so this disc is intended for solid platen use rather than dust-extraction setups. Sold individually with a minimum order quantity of 50 units per order.

Key Features

• 120-grit aluminum oxide abrasive — Fine grade, effective for blending and intermediate finishing
• X-weight cloth backing provides durability and resistance to tearing under load
• Pressure-sensitive adhesive mount — fast attachment and removal on PSA-compatible platens
• Flexible construction allows limited conformability on contoured work surfaces
• No vacuum holes — designed for solid platen disc sanders and benchtop motors
• 3M Series 348D construction with maroon disc color for easy grit identification

Compatibility

Compatible with benchtop motors, disc sanders, and random orbital sanders that accept 3-inch PSA abrasive discs. No vacuum port alignment required.

Installation Notes

Installation is performed by maintenance technicians, metalworkers, or fabricators servicing compatible abrasive machines. Power down and disconnect the sander or benchtop motor before changing discs. Peel the release liner from the PSA backing and press the disc firmly onto a clean, dry platen, working from the center outward to avoid air pockets. Inspect the disc for damage before each use and replace if backing shows tears or delamination.
