3M 31369 Cubitron II 5" Clean Sanding Disc 180+ Grit

The 3M Cubitron II Clean Sanding Disc features revolutionary 3M Precision-Shaped Grain technology with triangular-shaped ceramic mineral that cuts up to 30% faster than premium abrasives and lasts up to twice as long while delivering a finer, more uniform finish. Ideal for marine applications including bottom paint removal, gelcoat repair, and blister repair.

Key Features:

• Precision-Shaped Grain technology with triangular ceramic mineral continuously exposes fresh cutting edges as the abrasive wears for consistent, fast cutting action
• Advanced hole pattern provides superior dust extraction by allowing vacuum to reach virtually every part of the 5-inch disc surface
• Convenient Hookit attachment system for quick, secure disc changes on compatible backup pads
• 180+ grit provides fine finishing capability for smooth surface preparation
• Cuts faster and lasts longer than conventional abrasives, reducing disc changes and improving productivity

The Clean Sanding Disc design maximizes dust removal efficiency when used with vacuum-equipped sanders, maintaining a cleaner work surface and extending abrasive life. Perfect for professional marine technicians and boat owners who demand superior performance and finish quality.
