Abrasive fiber disc 3M Cubitron II 987C 125x22 mm, grit 80+, pack of 25

Abrasive fiber disc 3M Cubitron II 987C 125x22 mm, grit 80+, pack of 25 is a high-performance grinding accessory designed for metalworking. The disc combines Cubitron II ceramic abrasive with a robust fiber backing to deliver a fast cut rate and extended service life. Sized for a 125 mm backing pad with a 22 mm bore, this pack of 25 discs is intended for repetitive grinding and blending tasks where consistent material removal and durability are required.

Advantages

The Cubitron II ceramic abrasive provides a sharp, self-sharpening cutting action that maintains cutting speed and reduces loading compared with conventional abrasives. The fiber backing ensures flatness and strength for aggressive stock removal and improved control when used with angle grinders. A uniform abrasive coating and optimized grit distribution offer consistent performance across the disc surface, which helps extend useful life and reduce frequent disc changes.

Suitable for

• Removing weld beads and grinding weld seams on carbon steel and stainless steel
• Rust and scale removal from metal surfaces
• Surface shaping and beveling of metal parts
• Blending and finishing prior to painting or coating
• Workshop and industrial angle grinder operations

How to use

Install the disc on a compatible 125 mm backing pad with a 22 mm bore and secure it according to the angle grinder manufacturer’s instructions. Operate the angle grinder at the recommended speed range for the disc and the workpiece material. Use steady, even pressure and move the disc across the work surface to avoid concentrated heat buildup. Replace the disc when abrasive performance declines or the backing shows excessive wear.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection, gloves and respiratory protection. Match the grit to the task — grit 80+ is suitable for general-purpose grinding and blending on metal. Avoid excessive pressure or side loading that could cause premature disc failure. Store discs flat in a dry environment away from direct sunlight and high humidity.
