3M 7010299967 Psa Cloth Disc 348D 1.5 in 80 Grit Ao

Product Description

The 3M 7010299967 is a pressure-sensitive adhesive (PSA) cloth sanding disc in the 348D series, designed for heavy-duty material removal in industrial and trade grinding applications. The disc measures 1.5 inches in diameter and carries an 80-grit aluminum oxide abrasive on an X-weight cloth backing. It mounts directly to a backup pad or steel platen via a high-strength PSA layer, allowing fast disc changes without tools. The resin bond system resists heat buildup, extending usable disc life under sustained cutting loads. At a rated speed of 20,000 RPM, it delivers consistent stock removal across a range of surfaces.

This disc is suited for metal fabrication, woodworking, and surface preparation tasks where an aggressive grit and durable backing are required. The 80-grit aluminum oxide construction handles both wet and dry applications, making it a versatile choice for grinding, blending, and finishing work on ferrous metals, non-ferrous metals, and wood substrates. It is typically used by machinists, metal fabricators, and skilled tradespeople operating handheld or bench-mounted rotary tools equipped with a compatible backup pad or platen.

Key Features

• PSA backing adheres firmly to backup pads or steel platens and releases cleanly for fast replacement
• X-weight cloth backing resists tearing and edge wear during aggressive grinding passes
• Aluminum oxide abrasive provides fast cutting action and extended service life across multiple surface types
• Resin bond protects abrasive layer from heat damage, maintaining cut rate over the disc life
• Rated to 20,000 RPM for use with high-speed rotary tools
• Compatible with both wet and dry sanding applications

Compatibility

Designed for use with backup pads or steel platens that accept 1.5-inch PSA-mount sanding discs on rotary pneumatic or electric tools rated to 20,000 RPM or lower.

Installation Notes

Installation is performed by tradespeople or machine operators familiar with rotary abrasive tooling. Before mounting or changing discs, ensure the tool is powered off, depressurized if pneumatic, and the spindle has come to a complete stop. Confirm the tool and backup pad RPM rating meets or exceeds the disc rating before operation. Inspect the backup pad surface for contamination or debris before applying the PSA disc to ensure full adhesion.
