3M Cubitron II Fibre Disc 982C – 4-1/2 in, TN Quick Change, 36+ Grit PSG for Heavy Grinding

Powerful performance for heavy grinding and beveling

When metal finishing demands speed and durability, the 3M Cubitron II Fibre Disc 982C delivers. Built around 3M's Precision-Shaped Grain, it cuts aggressively yet stays cooler, reducing heat-related wear while maintaining sharp edges as the disc wears. The TN quick-change attachment makes disc swaps fast and simple, helping you move between tasks with minimal downtime.

Why this disc stands out

• SUPER-SHARP CUTTING: PSG creates sharp peaks that slice through metal quickly with less pressure
• LONGER DISC LIFE: Extended disc life means more parts finished per shift and fewer changes
• REDUCED CHANGEOUTS AND DOWNTIME: TN quick-change enables quick, tool-free disc swaps
• LONG-LASTING PERFORMANCE: Ceramic grain wears evenly, staying cooler and sharper over time
• DURABLE AND TEAR-RESISTANT: Stiff backing supports heavyweight grinding like weld removal and beveling

Great for heavy grinding on carbon steel

Optimized for carbon steel, this disc handles edge prep, weld removal, and finish work across large and small areas. The TN quick-change system smooths transitions in both manual and automated setups, contributing to consistent workflow.

Usage considerations: compatible with pneumatic or electric tools, and usable in dry or wet environments. For stainless steel tasks, 3M offers a specialized option (987C) that may suit different material needs.

Production-ready reliability

With long disc life and cooler operation, this disc helps maintain high cut rates throughout its life, supporting steady productivity and reduced operator fatigue in demanding shop environments.
