3M 7100044448 Cubitron Ii 732U Sanding Disc 80 Grit 5 Inch

Product Description

The 3M 7100044448 is a coated abrasive hook-and-loop sanding disc from the Cubitron II 732U line, built around 3M Precision Shaped Grain technology. The triangular ceramic mineral is engineered to slice through material rather than plow or gouge like conventional abrasives. At 5 inches in diameter and 80 grit, this disc delivers aggressive stock removal with a controlled cut. Compared to standard abrasive discs, it cuts up to 2 times faster and lasts up to 4 times longer, reducing disc changes and downtime on the job. It is suited for use by metalworkers, fabricators, auto body technicians, and finishing trade professionals.

This disc is designed for stock removal applications across a wide range of substrates including bare metal, painted surfaces, and composites. The hook-and-loop backing allows fast, tool-free disc swaps, which increases productivity during high-volume finishing or surface prep work. The multi-hole pattern is precisely laid out to maximize dust extraction when used with a compatible dust collection system, keeping the work surface clear and extending disc life.

Installation Notes

Ensure the sander backing pad is clean and free of debris before attaching the disc to maintain proper hook-and-loop engagement. Power down and disconnect the sander before changing discs. Inspect the backing pad regularly for wear, as a damaged pad reduces disc adhesion and can affect cut quality. Follow all applicable safety guidelines for abrasive grinding and surface preparation in your trade.
