Model number
31361

The 3M Cubitron II Hookit Clean Sanding Abrasive Disc 31361 is a 3-inch hook-and-loop disc designed for collision repair and small-surface bodywork. Precision-shaped triangular grain cuts 30% faster than conventional premium abrasives and self-sharpens to last twice as long. The multi-hole clean sanding pattern maximizes dust extraction for a cleaner work environment. Hookit attachment allows fast disc swaps on 3-inch random orbital sanders and detail sanders. Sold in 50-disc packs for professional shop use.

§ FAQ

What is the pack size for the 31361?

The 31361 is sold in a 50-disc pack, making it cost-effective for professional collision repair shops that go through discs quickly.

How does Cubitron II compare to standard aluminum oxide at 80 grit?

Cubitron II's precision-shaped grain cuts faster and lasts longer than standard aluminum oxide. At 80 grit you get aggressive stock removal without the rapid dulling typical of conventional abrasives, reducing disc changes and saving time on large bodywork jobs.

Is the 31361 for professional or consumer use?

The 31361 is intended for industrial and occupational use in collision repair shops. It is not marketed for consumer or general home use, though the Hookit attachment system is compatible with standard 3-inch random orbital tools.

Does the 3-inch size restrict compatible sanders?

Yes. The 31361 requires a 3-inch random orbital or dual-action sander with a Hookit-compatible hook-and-loop pad. Common options include 3M's own 3-inch sanders used in collision repair applications.
