3M Cubitron II Hookit Clean Sanding Abrasive Disc

The 3M Cubitron II Hookit Clean Sanding Abrasive Disc (series 737U) is a hook-and-loop sanding disc built for automotive collision repair and refinishing. It pairs 3M Precision Shaped Grain with a multi-hole dust extraction pattern. The result is a fast-cutting, long-lasting sanding disc that stays cleaner than conventional discs. It is also known as a Cubitron II clean sanding disc or Hookit DA sanding disc.

Key Features:

• Precision Shaped Grain technology: triangular, electrostatically oriented grains form sharp peaks that slice through paint and body filler. 3M states they cut at least 30% faster and last at least 30% longer than traditional ceramic abrasives.
• Less pressure required: the sharper cutting surface needs less force, which helps give consistent results.
• Clean Sanding multi-hole pattern: gives excellent dust extraction on dust-extraction sanders. This helps raise cut rate and disc life and keeps the work surface cleaner.
• Hookit hook-and-loop attachment: the disc attaches firmly to a hook-and-loop backup pad (sold separately). It removes cleanly for quick disc changes and can be reused for the life of the abrasive.
• Wide range of grades: the line covers coarse body work through fine sanding of blending areas.

Typical Applications:

• Paint removal
• Shaping body filler
• Fine feather-edging
• Final prep before priming or blending
• Removing the surface structure of clearcoats and preparing blending areas

When the disc is used with a 3M Clean Sanding Disc Pad, the disc holes do not need to line up with the pad holes. This makes disc changes fast and convenient. Cubitron II Hookit Clean Sanding Discs give auto body professionals a long-lasting, high-performance abrasive from a trusted name in abrasives.
