3M 7100066675 Cubitron Ii Hookit Sanding Disc 5 in 150 Grit

Product Description

The 3M 7100066675 is a 5-inch hook-and-loop abrasive sanding disc from the Cubitron II 732U series, designed for aggressive stock removal on a wide range of substrates. It uses 3M Precision Shaped Grain technology, a ceramic mineral formed into triangular shapes that slice through material rather than plowing or gouging like conventional abrasives. The result is a disc rated to cut up to two times faster and last up to four times longer than standard abrasive discs. At 150 grit, it is suited for finishing and blending work where controlled material removal is needed. This disc is installed and used by metal fabricators, auto body technicians, woodworkers, and general trades professionals.

The 732U disc is built for surface preparation, stock removal, and blending across metal, wood, and composite substrates. The hook-and-loop attachment system allows fast disc swaps without tools, reducing downtime during production or repair work. A precise multi-hole pattern in the disc face promotes efficient dust extraction when used with a compatible vacuum or dust collection system, keeping the work surface cleaner and extending disc life by reducing loading.

Installation Notes

Ensure the sander backing pad is clean and free of debris before attaching the disc to achieve a secure hook-and-loop bond. Align the disc holes with the backing pad holes to maintain dust extraction performance. Operate at the speed rating appropriate for the tool and application. Inspect the disc before each use and discard any disc showing tears, missing segments, or excessive loading.
