3M 7010326621 Sanding Disc 50 Grit 6 Inch Hook Loop

Product Description

The 3M 7010326621 is a hook-and-loop abrasive sanding disc engineered for heavy-duty stock removal on composites and metal. The disc uses a ceramic and aluminum oxide blend on an open coat construction, which keeps the abrasive surface clear of debris and maintains a consistent cut rate throughout the disc life. An E-weight paper backing provides the rigidity needed for aggressive sanding tasks, and an anti-loading stearate coating resists buildup. The 6-inch diameter and 50-grit rating make this disc well suited for rapid material removal in demanding shop and field applications. Installation and disc changes are handled by a hook-and-loop attachment system.

This disc is designed for use with 3M Clean Sanding System tools. The multi-hole pattern aligns with compatible tool pad perforations to maximize dust extraction, extending disc life and improving visibility at the work surface. Typical applications include sanding composite panels, bare metal, body filler, and similar substrates in auto body, fabrication, and industrial finishing work. Licensed trades and production shops that require consistent, repeatable abrasive performance in dusty environments will find this disc a practical fit.

Key Features

• Ceramic and aluminum oxide blend delivers high cut rate and extended disc life on composites and metal
• Open coat construction resists loading from dust and debris during heavy stock removal
• Multi-hole disc design maximizes dust evacuation when paired with 3M Clean Sanding System tools
• Engineered to resist edge shelling under rugged, high-pressure sanding conditions
• Hook-and-loop attachment allows fast, secure disc changes without tools
• Anti-loading stearate coating on E-weight paper backing reduces disc glazing

Compatibility

Designed for use with 3M Clean Sanding System hook-and-loop backup pads and random orbital sanders configured for multi-hole dust extraction. Verify that the tool pad hole pattern aligns with the disc hole layout before use.

Installation Notes

Disc changes require no tools — press the disc firmly onto a compatible hook-and-loop backup pad until the fastening surface is fully seated. Inspect the backup pad for worn hooks before each disc swap, as a degraded pad reduces holding force and can allow disc slippage during use. Operate the sander at the speed recommended by the tool manufacturer for the disc diameter and grit selected. Disconnect or power down the sander before mounting or removing any abrasive disc.
