3M 31361 Cubitron II Marine Sanding Disc with Hookit Attachment

The 3M Cubitron II Marine Sanding Disc features revolutionary triangular-shaped ceramic mineral technology that cuts 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 technology provides superior cut rate and extended disc life
• Self-sharpening triangular grains continuously expose fresh cutting edges as the disc wears
• Multi-hole pattern maximizes dust extraction, allowing vacuum systems to reach virtually every part of the disc surface
• Hookit attachment system enables quick, secure disc changes without adhesives
• Engineered specifically for marine environments and materials
• Produces consistent, fine finishes that reduce follow-up sanding steps

This marine-grade sanding disc combines 3M's proven Cubitron II technology with an optimized hole pattern for superior dust removal, helping maintain disc performance and visibility during use. The convenient Hookit backing system ensures fast disc changes and reliable attachment to compatible backup pads.
