3M 7010294666 Psa Cloth Disc 5 Inch 50 Grit Aluminum Oxide

Product Description

The 3M 7010294666 is a PSA (Pressure-Sensitive Adhesive) cloth sanding disc engineered for heavy-duty material removal in industrial and trade grinding applications. The disc uses an aluminum oxide abrasive bonded with a resin system that resists heat buildup, extending service life under continuous use. It runs at up to 12,000 RPM on a 5-inch backup pad or steel platen. The X-weight cloth backing handles aggressive stock removal without tearing or edge breakdown. Suitable for both wet and dry sanding operations, this disc is built for fabricators, metalworkers, and finishing tradespeople who cycle through abrasives at a high rate.

This disc is used in metal fabrication shops, weld grinding, surface prep, and general industrial finishing where fast, consistent stock removal is required. The PSA backing mounts and releases quickly from compatible 5-inch backup pads or steel platens, reducing downtime during disc changes. At 50 grit, it is suited for aggressive material removal rather than fine finishing passes. Both wet and dry use cases are supported, making it versatile across different shop setups and workpiece materials.

Key Features

• Pressure-Sensitive Adhesive backing adheres firmly to backup pads and steel platens, releasing cleanly for fast replacement
• Aluminum oxide abrasive provides fast cutting action and consistent long service life across a range of surfaces
• Resin bond system resists heat damage and extends disc life during sustained, high-speed use
• X-weight cloth backing supports aggressive applications without tearing or edge wear
• Rated for wet and dry sanding applications
• Operates at up to 12,000 RPM

Compatibility

Designed for use with 5-inch PSA backup pads or steel platens in standard disc grinder and finishing machine setups.

Installation Notes

Mounting is performed by pressing the PSA backing firmly onto a clean, dry 5-inch backup pad or steel platen. Ensure the backup pad surface is free of debris or residual adhesive before attaching the disc to maintain proper bond and disc concentricity. Always confirm that the tool spindle speed does not exceed the disc maximum rating before starting. Disc replacement should be done with the tool unplugged or air supply disconnected.
