3M 051141-27655 Cubitron II Fibre Disc 987C 7" x 7/8" 60+ Grit

The 3M Cubitron II Fibre Disc 987C is a high-performance grinding disc powered by revolutionary Precision-Shaped Grain technology for heavy-duty metalworking applications. This 7-inch diameter disc features a 60+ grit rating and a 7/8-inch center hole, making it ideal for use with standard angle grinders on stainless steel, aluminum, nickel bronze, and other softer metals.

Key Features:

• Precision-Shaped Ceramic Grain forms triangular structures that slice through metal rather than gouging, providing exceptionally fast cutting with less pressure
• Self-sharpening grain continuously exposes new cutting edges as points break off, significantly extending disc life
• Stiff fiber backing with strong resin bond provides durability and tear-resistance for high-pressure applications
• Grinding aid keeps workpiece cooler, protecting heat-sensitive alloys from thermal damage and reducing discoloration
• Cuts up to twice as fast as conventional ceramic discs with noticeably less operator fatigue
• Can be used wet or dry for versatile grinding applications

Ideal for weld grinding, beveling, edge chamfering, removing mill scale, smoothing pits and imperfections, and machining grooves. The 60+ grit designation indicates the disc contains abrasive particles of 60 grit and finer for optimal material removal and surface finish. Perfect for robotic grinding operations and high-pressure manual grinding where productivity and extended disc life are critical.
