3M Cubitron II Clean Sanding Hookit Disc

The 3M Cubitron II Clean Sanding Hookit Disc (also sold as the Cubitron II Hookit Clean Sanding Abrasive Disc 737U) is a hook-and-loop sanding disc built for automotive paint and body repair. It pairs 3M Precision-Shaped Grain with a multi-hole dust extraction pattern. The result is a fast-cutting, long-lasting abrasive for random orbital and disc sanders.

Key Features:

• 3M Precision-Shaped Grain: The sharp, triangular ceramic grains cut faster and last longer than conventional ceramic abrasives. They also need less pressure.
• Clean Sanding multi-hole pattern: The pattern gives excellent dust extraction when the disc is used with a matching vacuum-assisted backup pad.
• Hookit hook-and-loop attachment: Discs change out quickly. They come off cleanly and can be reused for the life of the abrasive.
• Paper backing with resin bond and open coat: This construction gives a consistent finish and resists clogging.

Applications: These discs suit paint removal, rough body filler shaping, fine feather-edging, and final prep before blending or priming. They are widely used in automotive, marine and general paint preparation work.

Less dust and fewer disc changes mean cleaner work areas and less time spent sanding.
