3M 33391 3" Cubitron II Fibre Roloc Disc 36+ Grit

The 3M 33391 Cubitron II Roloc Fibre Disc is a 3-inch abrasive disc engineered with advanced precision-shaped grain technology for superior cutting performance. Designed for use with Roloc quick-change systems, this disc delivers exceptional material removal rates while running cooler and requiring less grinding pressure than conventional abrasives.

Key Features:

• 3M Precision-Shaped Grain (PSG) maintains super-sharp points that cut exceptionally fast with less operator pressure
• Triangular-shaped ceramic grain wears evenly and optimizes mineral breakdown for consistent performance
• Runs cooler during grinding operations, reducing heat-related workpiece damage
• Lasts up to five times longer than conventional fibre discs, completing more parts per disc
• Reduces disc changes and downtime for increased productivity
• Roloc quick-change attachment system for fast, tool-free disc changes
• Fiber backing provides durability and tear resistance during aggressive grinding

Ideal for grinding, blending, and finishing applications on metal surfaces including steel, stainless steel, and other alloys. The 3-inch diameter makes this disc perfect for detail work, tight spaces, and contoured surfaces where precision control is essential.
