3M 31366 Cubitron II Marine Sanding Disc with Hookit Attachment

The 3M Cubitron II Marine Sanding Disc features revolutionary triangular-shaped ceramic mineral technology that cuts up to 30% faster than premium abrasives while lasting up to twice as long. This advanced abrasive delivers a finer, more uniform finish, making it ideal for demanding marine applications including bottom paint removal, gelcoat repair, and blister repair.

Key Features:

• Precision-shaped ceramic grain with cutting edges that continually self-sharpen as the disc wears, maintaining consistent performance throughout its life
• Optimized hole pattern enables superior dust extraction, allowing vacuum systems to reach virtually every part of the disc surface for cleaner work and better visibility
• Convenient Hookit attachment system for quick, tool-free disc changes
• Engineered specifically for marine environments and fiberglass surfaces
• Reduces operator fatigue with faster material removal and less pressure required

This high-performance sanding disc combines 3M's Cubitron II ceramic technology with a marine-specific design to help professionals and DIYers achieve superior results in less time on boat maintenance and repair projects.
