3M 7000118915 Psa Disc 1 in 100 Grit Aluminum Oxide

Product Description

The 3M 7000118915 is a pressure-sensitive adhesive (PSA) abrasive disc designed for fine-grit material removal and surface finishing in trade and light industrial applications. At 1 inch in diameter with 100 grit aluminum oxide abrasive, this disc delivers consistent stock removal on metal, composites, and similar substrates. The X-weight cloth backing provides durability and flexibility, allowing the disc to conform to contoured surfaces without tearing. The PSA mount eliminates the need for mechanical fasteners, making disc changes fast during production or service work. This disc is part of the 3M 348D series and is sold individually with a minimum order quantity of 50 units.

This disc is suited for bench top motor applications and random orbital sanders in fabrication, maintenance, and finishing environments. The fine 100 grit rating makes it appropriate for intermediate finishing passes where surface prep and smoothness are priorities before final finishing or coating. The flexible cloth backing and maroon color are consistent with the 348D series construction, which is built for demanding surface contact work on curved and flat workpieces alike.

Key Features

• 100 grit aluminum oxide abrasive for fine-grade material removal and surface finishing
• X-weight cloth backing provides strength and flexibility for conforming to curved surfaces
• Pressure-sensitive adhesive (PSA) mount for fast, tool-free disc changes
• No vacuum holes — suited for solid backup pad configurations
• Compatible with bench top motors and random orbital sanders
• Flexible construction handles contoured and irregular workpiece geometry

Compatibility

Designed for use with bench top motors and random orbital sanders that accept 1-inch PSA-mount abrasive discs with solid backup pads. No vacuum holes are present, so use with non-perforated backup pad configurations only.

Installation Notes

Ensure the backup pad is clean and free of debris before applying the PSA disc to achieve full adhesive contact. Power down or unplug the sander or bench motor before mounting or removing discs. Press the disc firmly onto the backup pad and allow a moment for the adhesive to seat before operating at speed. Dispose of worn discs before adhesive failure occurs to prevent disc separation during use.
