3M Fibre Disc 787C

The 3M Fibre Disc 787C is a resin-bonded abrasive fibre disc for heavy stock removal, grinding, and weld blending on metal. It is also called a 3M 787C abrasive grinding disc or ceramic fibre sanding disc. The discs use a ceramic abrasive grain and are made for use on a backup pad with a right-angle grinder.

Key Features:

• Ceramic abrasive grain that stays sharp and wears down gradually by fracturing
• Fibre backing that is durable and flexible, suited to aggressive grinding and finishing work
• Suited to stainless steel, carbon steel, alloy steels, and other metals
• Faster cutting and longer life than conventional abrasive fibre discs in many applications
• Cooler cutting action that helps reduce heat build-up and workpiece discoloration

The 787C line is for fabrication, weld preparation, deburring, and metal finishing jobs where fast cut rates and long disc life matter. Choose the grit and diameter that match your grinder, backup pad, and application.
