Our Cubitron II Hookit Clean Sanding Sheet Rolls 737U was developed for superior cut and long life during key stages in auto body repair. Its long lasting triangular shaped grain and multi hole pattern for superior dust extraction make the sheet ideal for paint removal, rough body filler shaping, fine feather edging or final prep before blending or priming. Our Hookit system makes for quick change outs of abrasive sheets. This abrasive is ideal for feather edging, as a final sanding step before priming, or during prep before blending.
Cubitron II and Precision Shaped Grain
Cubitron II abrasive discs, file sheets and sheet rolls have raised the bar for high performing abrasives. Cubitron II abrasives feature our Precision Shaped Grain (PSG) technology, which helps provide faster cut. The result: Cubitron II cuts 30% faster and lasts 30% 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. Hookit sanding abrasives conveniently and firmly attach to a hook and loop backup pad (sold separately), 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 Sheet Rolls significantly increases cut rate and abrasive life. We have placed hundreds of small holes in a chevron formation to facilitate efficient dust extraction. Our unique kiss cut scoring technology makes it easy to select whatever sheet length is best for the project.
