3M 7000045068 Psa Disc 3 Inch 180 Grit Aluminum Oxide

Product Description

The 3M 7000045068 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for material removal and surface finishing applications. Built on an X-weight cloth backing, it delivers the rigidity and tear resistance needed for demanding grinding and finishing work. The disc uses aluminum oxide as the abrasive material, a durable mineral well suited to ferrous and non-ferrous metals, composites, and wood. At 180 grit, it falls in the very fine grade range, making it appropriate for finish sanding and surface prep before coating or inspection. The flexible construction allows the disc to conform to slightly contoured surfaces without losing consistent abrasive contact.

This disc is designed for use on random orbital sanders and is compatible with PSA-style backing pads. It is commonly used in metal fabrication shops, automotive body work, woodworking facilities, and general manufacturing environments. The 3-inch diameter fits standard small-diameter PSA pads used in precision finishing and detail work. No vacuum holes are included, so it is intended for use on solid backing pads. It is sold individually but requires a minimum order quantity of 50 units, making it well suited for production or shop-supply purchasing.

Key Features

• Aluminum oxide abrasive provides consistent cut rate on metal, wood, and composite surfaces
• X-weight cloth backing resists tearing under pressure and lateral stress
• 180 grit very fine grade for finish sanding and pre-coating surface prep
• Flexible construction conforms to mild surface contours for even stock removal
• PSA mount system allows fast disc changes on compatible backing pads
• No vacuum holes — designed for use with solid PSA backing pads

Compatibility

Designed for use with random orbital sanders equipped with 3-inch PSA-style backing pads. No specific model compatibility data was provided in the product input.

Installation Notes

Installation is performed by a technician or operator applying the disc directly to a clean, dry PSA backing pad — ensure the pad surface is free of dust and adhesive residue before mounting. Power down or unplug the sander before attaching or removing any disc. Inspect the disc for damage before use and do not exceed the tool manufacturer's rated RPM for the backing pad. Proper eye protection and dust control measures should be followed in accordance with applicable workplace safety standards.
