3M 34449 Cubitron II Hookit Clean Sanding Sheet Roll 70mm x 12m 320+

3M 34449 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, long abrasive life and outstanding dust extraction. Engineered for professional automotive refinishing, it provides fast, consistent sanding while helping maintain a cleaner working environment.

The 320+ grit is ideal for final primer sanding, blend preparation, denibbing and preparing surfaces before basecoat application. Precision-Shaped Grain continually fractures to expose fresh cutting edges, allowing the abrasive to cut faster, run 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 custom sheet lengths, reducing waste and improving workshop efficiency.

Ideal for collision repair, automotive refinishing, marine repairs and industrial finishing applications, the 70mm x 12 metre roll delivers premium sanding performance and a consistently refined surface ready for painting.
