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 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. Cubitron™ II cuts 30% faster and lasts 30% longer than conventional ceramic abrasives. 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. 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.
