3M™ Cubitron™ II Hookit™ Marine Sanding Abrasive Discs 737U

Our Cubitron II Hookit Marine Sanding Abrasive Discs 737U combines the highest 3M technology for marine repair. Its long-lasting triangular shaped grain and multi-hole pattern for superior dust extraction make the disc ideal for paint removal, rough body filler shaping, fine feather-edging or final prep before blending or priming. Our Hookit system makes for quick disc change-outs.

Cubitron™ II Hookit™ Marine Sanding Abrasive Discs 737U was developed for superior cut and long disc life during key stages in auto body repair. It features Precision-Shaped Grain technology (PSG)-triangular-shaped, electrostatically oriented grains form sharp peaks, each acting like an individual cutting tool that slices through paint and body filler. This grain cuts 30% faster than other premium abrasives. The disc is ideal for featheredging, as a final sanding step before priming, or during prep before blending. Individual edges in the shaped grain also self-fracture to continually present a sharp cutting surface, making the cut more consistent and prolonging the life of the disc.

3M™ Cubitron™ II abrasive discs, file sheets and sheet rolls have raised the bar for high-performing abrasives. Cubitron™ abrasives feature Precision-Shaped Grain (PSG) technology, which allows engineers to control the geometry of the abrasive grain for a truly fast, efficient cut. Instead of simply crushing the abrasive into particles, 3M uses microreplication to create uniformly sized ceramic grains and precisely shape them into triangular structures-essentially, sharp peaks that slice, not plow, through paint and metal. These grains are electrostatically oriented on the abrasive surface and blended with an aluminum oxide mineral for the most efficient cut and even wear. What's more, PSG fractures during use to maintain sharp abrasive edges. The result: Cubitron™ II cuts 30% faster and lasts 2x longer than conventional ceramic abrasives.
