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.

Precision Shaped Grain Advantage

Featuring 3M’s Precision-Shaped Grain technology, the sanding sheets cut at least 30% faster and last 30% longer than conventional ceramic abrasives. This triangular-shaped grain improves cutting efficiency and durability.

This sharper cutting surface reduces the pressure needed during sanding, which helps minimize user fatigue and enhances control. It’s ideal for paint removal and body filler shaping.

Effective Dust Extraction Design

The Clean Sanding multi-hole pattern on these sheets significantly improves dust extraction. Hundreds of small holes arranged in a chevron pattern help keep the work area cleaner and extend abrasive life.

This design is especially useful during automotive repair, where dust control is critical. It supports finer feather edging and final prep before blending or priming.

Convenient Hookit System

The Hookit hook-and-loop backing firmly attaches the abrasive sheets to compatible pads, allowing quick changes without adhesive residue. This system supports repeated use throughout the abrasive’s lifespan.

It’s perfect for busy workspaces where fast change-outs save time. The 80 mm width and 12 m length per roll provide ample material for multiple projects.

Flexible Sheet Roll Format

This product comes as a case of 5 rolls, each 80 mm wide and 12 m long, allowing users to cut sheets to the desired length. Kiss-cut scoring technology makes tearing off the right size easy and precise.

The roll format suits various sanding needs, from rough shaping to final finishing. Having multiple rolls in a case ensures you have enough supply for extended use.
