3M CUBITRON™ II 737U HOOKIT CLEAN SANDING SHEET ROLLS  |  115MM 

3M’s Cubitron™ II Hookit™ Clean Sanding Abrasive Disc 737U combines the highest 3M technology for automotive 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 sheet change-outs.

3M developed the Cubitron™ II Hookit™ Clean Sanding Abrasive Disc 737U for superior cut and long disc life during key stages in auto body repair. It features 3M™ Precision-Shaped Grain technology – 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 traditional premium abrasives. The sheet is ideal for feather-edging, 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.

About Cubitron II and Precision-Shaped Grain

3M™ Cubitron II products have raised the bar for high-performing abrasives. It utilizes 3M™ Precision-Shaped Grain, which outcuts and outlasts conventional ceramic industrial abrasives and requires less grinding force to achieve superior performance. The result is that operators can grind faster and complete more parts per disc with less muscle-work and fatigue.

To create PSG, 3M engineers started with 3M™ Ceramic Abrasive Grain and used proprietary technology to form the grains into triangular structures and electrostatically orient them on the backing to form sharp peaks that maximize cutting potential. These peaks slice cleanly through metal like a knife through butter, rather than gouging or plowing as traditional abrasives do, and continuously self-sharpen as the points break off. This generates a super-fast cut and lessens heat build-up due to friction, reducing heat-related stress cracks and discoloration.

PSG also wears evenly, and because the abrasive itself stays cooler and sharper, Cubitron II products last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications.

About Hookit™

3M offers a complete range of hook-and-loop style Hookit™ discs for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. They are often used in applications where an adhesive backed disc may be too aggressive, as Hookit™ discs tend to leave finer finishes. Hookit™ sanding discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.

About 3M™ Clean Sanding

The multi-hole pattern on 3M™ Clean Sanding discs evacuates dust better than 5- or 6-hole products—significantly increasing cut-rate and roll life. For maximum dust removal, 3M has added hundreds of small holes which have been purposely arranged in a chevron formation.
