Technical Specifications

3M™ Hookit™ hook-and-loop style abrasive attaches firmly, removes quickly for fast change-out
Precision Shaped Grain (PSG) technology employs microreplication to obtain sharp and uniformly sized triangular grain
Triangular PSG abrasive grains are super-sharp and cut exceptionally fast
Sharp tips of PSG maintains abrasive life for a long time
Sharper cutting surface means less pressure is required for reduced friction and wear
Grains are electrostatically oriented on abrasive surface for efficient cut, even wear
Dust-free versions available
Cubitron™ II cuts 30% faster and lasts 2x longer than other premium abrasives

We developed our 3M™ Cubitron™ II Hookit™ File Sheets 737U for superior cut and long life during key stages in auto body repair

Kiss-cut scoring technology allows for use in multiple sheet lengths

3M developed 3M™ Cubitron™ II Hookit™ File Sheets 737U for superior cut and long 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 conventional ceramic abrasives. This abrasive is ideal for stripping paint to metal, shaping and sanding plastic filler, scuff sanding before painting, removing dust nibs and reducing excess orange peel. 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 abrasive. Files sheets are available in both no-holes and dust-free versions.

3M™ Cubitron™ II abrasive discs, file sheets and sheet rolls have raised the bar for high-performing abrasives.

About 3M™ Cubitron™ II and Precision-Shaped Grain
3M™ Cubitron™ II abrasive discs, file sheets and sheet rolls have raised the bar for high-performing abrasives. Cubitron™ abrasives feature our Precision-Shaped Grain (PSG) technology, which allows our 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.

About Hookit™
3M offers a complete range of hook-and-loop style Hookit™ abrasives for work spaces where adhesive backed products may become contaminated by dust, dirt, or flying debris. They are often used in applications where an adhesive backed sheet may be too aggressive, as Hookit™ abrasives tend to leave finer finishes. Hookit™ sanding
