3M 7010326978 Abrasive Disc 3 Inch P120 Grit Ao Film

Product Description

The 3M 7010326978 is a 3-inch hook-and-loop abrasive disc in the 255L series, designed for fast cut rates and close-tolerance finishing on wood, paint prep, and defect repair. It uses aluminum oxide abrasive grain bonded to a flexible film backing. The film backing resists tearing better than comparable paper-backed discs and delivers a consistent finish across the work surface. An open-coat construction with a load-resistant coating keeps the disc from clogging with dust and debris, making it well suited for high-production finishing environments. Licensed tradespeople, auto body technicians, and finish carpenters rely on this disc for repeatable results.

This disc is designed for surface preparation and finishing work including paint prep, defect removal, and wood finishing. The hook-and-loop attachment system allows quick disc changes and reuse over the life of the abrasive, which supports efficient workflow in production settings. The flexible film backing conforms to contours, making it useful on both flat and slightly curved surfaces where a uniform finish is required.

Key Features

• Aluminum oxide grain delivers a fast cut with long service life across a wide range of surfaces
• Flexible film backing resists tearing and outperforms comparable paper-backed discs in durability
• Open-coat construction provides an aggressive cut rate
• Load-resistant coating prevents clogging from dust and debris during use
• Hook-and-loop attachment system allows fast disc changes and supports disc reuse

Compatibility

Designed as an OEM-style replacement and standard fitment for 3-inch hook-and-loop random orbital sanders and disc sanders used in wood finishing, automotive paint prep, and surface defect repair applications.

Installation Notes

This disc is installed by pressing the hook-and-loop backing firmly onto a compatible 3-inch backup pad. Ensure the sander is powered off and unplugged before changing discs. Inspect the backup pad for wear before attaching a new disc, as a damaged pad surface can reduce abrasive performance and cause uneven wear.
