3M 34446 Cubitron II Hookit Clean Sanding Sheet Roll 70mm x 12m 180+

3M 34446 Cubitron II Hookit Clean Sanding Sheet Roll combines 3M Precision-Shaped Grain technology with a clean sanding multi-hole design to deliver exceptional cutting speed, extended abrasive life and superior dust extraction. Designed for professional automotive refinishing, it removes material efficiently while reducing loading and improving overall sanding performance.

The 180+ grit is ideal for shaping body filler, feather edging repair areas, primer sanding and preparing surfaces before basecoat application. Precision-Shaped Grain continuously fractures to expose fresh cutting edges, allowing the abrasive to cut faster, stay cooler and last significantly longer than conventional ceramic abrasives.

The Hookit hook and loop backing provides secure attachment to compatible sanding blocks while allowing quick abrasive changes. Kiss-cut scoring enables the roll to be torn into the exact sheet length required, reducing waste and increasing workshop efficiency.

Perfect for collision repair, automotive refinishing, marine applications and industrial surface preparation, the 70mm x 12 metre roll delivers consistent, professional sanding performance across a wide range of repair tasks.
