3M 076308-89655 Fibre Disc 787C 5 Inch x 7/8 Inch 120+ Grit

The 3M Fibre Disc 787C features advanced 3M Precision Shaped Grain technology, engineered for ultra-rapid cutting performance on challenging metalworking applications. This 5-inch disc with 120+ grit and 7/8-inch arbor hole is optimized for stainless steel and non-ferrous metals like aluminum and titanium, delivering superior cut rates and extended disc life compared to conventional ceramic fiber discs.

Key Features:

• Precision Shaped Ceramic Grain rapidly cuts hard-to-grind metals including stainless steel and high nickel alloys
• Integrated grinding aid minimizes grinding temperatures, keeping disc and workpiece cool for heat-sensitive alloys
• Stiff fiber backing with strong resin bond provides exceptional durability and tear resistance
• Maximum operating speed of 12,000 RPM for high-production environments
• Orange closed-coat construction for consistent performance
• Enables operators to complete more parts per disc, reducing disc changes and downtime

Ideal for demanding applications including weld removal, beveling, edge chamfering, blending, and finish refinement. The 787C series balances optimal speed and longevity, making it an excellent choice for high-production metalworking shops seeking to maximize throughput while controlling costs.
