3M 7010326509 Psa Cloth Disc 18 Inch 40 Grit Ao

Product Description

The 3M 7010326509 is a PSA cloth sanding disc designed for heavy-duty material removal in industrial and trade applications. The disc uses a Pressure-Sensitive Adhesive backing that mounts directly to a backup pad or steel platen, allowing fast installation and clean removal when it is time to swap discs. The aluminum oxide abrasive delivers aggressive cutting action with a long service life across a wide range of ferrous and non-ferrous surfaces. A resin bond system protects the abrasive layer from heat buildup, extending disc life during sustained use. Licensed contractors, metal fabricators, and surface prep technicians are the primary installers of this product.

This disc is suited for heavy stock removal, weld blending, and surface conditioning on metal, wood, and composite substrates. At 18 inches in diameter with a 40-grit cut, it is sized for large-diameter rotary machines and wide-format finishing equipment common in fabrication shops, industrial maintenance, and large-scale surface prep. The disc supports both wet and dry sanding environments, giving it flexibility across job types.

Key Features

• Pressure-Sensitive Adhesive backing adheres securely to backup pads or steel platens and releases cleanly for fast disc changes
• X-weight cloth backing withstands aggressive applications without tearing or edge wear
• Aluminum oxide abrasive cuts fast and maintains performance across a wide range of surfaces
• Resin bond system resists heat damage, extending disc service life under sustained load
• Suitable for both wet and dry sanding applications
• 18 inch diameter suits large-format rotary machines and wide-area surface prep

Compatibility

Designed for use with backup pads and steel platens that accept 18 inch PSA-mount sanding discs on large-diameter rotary or orbital sanding machines.

Installation Notes

This disc is typically installed by fabricators, surface prep technicians, or trades professionals operating large rotary sanding equipment. Power down and de-energize all machinery before mounting or removing the disc. Peel the release liner and align the disc squarely on the backup pad or steel platen before pressing firmly to ensure full adhesive contact. Inspect the disc for tears or worn abrasive before each use and replace when cutting efficiency drops.
