3M 7100066679 Cubitron Ii 732U Disc 6 Inch 180 Grit

Product Description

The 3M 7100066679 is a Cubitron II Hookit Clean Sanding Paper Disc in the 732U series, engineered for high-performance material removal in demanding surface preparation applications. It features 3M Precision Shaped Ceramic Grain — a triangular mineral geometry that slices through substrate material rather than gouging or plowing like conventional abrasives. At 6 inches in diameter and 180 grit, this disc is built for controlled stock removal and finish work. The hook-and-loop attachment system enables fast disc changes, and a precise multi-hole pattern supports efficient dust extraction during use. Licensed trades and finishing professionals are the primary installers and users of this product.

This disc is suited for stock removal and surface preparation across a wide variety of substrates, including metals, composites, and wood. It is commonly used in automotive body shops, fabrication facilities, and general industrial finishing environments. The 180 grit rating positions it for intermediate to final stock removal passes where surface consistency matters. The multi-hole dust extraction pattern makes it compatible with vacuum-assisted sanders and clean-sanding systems, reducing airborne particulate and improving visibility of the work surface during operation.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate rather than gouging, delivering faster cut rates
• Cuts up to 2 times faster than conventional abrasives
• Lasts up to 4 times longer than conventional abrasives
• Hook-and-loop backing for fast, tool-free disc changes
• Precision multi-hole pattern enables superior dust extraction
• Suitable for a wide range of substrates with a focus on stock removal

Compatibility

Designed for use with 6-inch hook-and-loop random orbital and orbital sanders equipped with compatible multi-hole dust extraction backing pads.

Installation Notes

Ensure the sander backing pad is clean and free of debris before attaching the disc — contamination on the hook-and-loop surface reduces holding force and can cause disc slippage. Operate at the RPM rating specified for the sander; do not exceed the disc's rated speed. Wear appropriate respiratory protection and eye protection during use, particularly when dust extraction is not fully sealing the work area.
