Abrasive Fiber Disc 3M 125x22 mm K60 Cubitron II for Steel, Pack of 25

Abrasive Fiber Disc 3M 125x22 mm K60 Cubitron II for Steel, Pack of 25 is a fiber-backed abrasive designed for metalworking tasks on steel. The disc measures 125 mm in diameter with a 22 mm arbor hole and has a K60 ceramic-based Cubitron II grit that combines fast cutting action with extended life compared with conventional abrasives. Supplied in a pack of 25, these discs are intended for use on standard 125 mm angle grinders and are suitable for operations such as grinding, deburring and surface preparation on steel components.

Advantages

The Cubitron II ceramic grain provides a consistent cutting geometry that increases material removal rate while maintaining disc life. The fiber backing offers strength and resistance to tearing during aggressive grinding, and the uniform grit distribution helps to reduce loading and clogging on steel surfaces. The 22 mm arbor size ensures compatibility with common angle grinders, and the pack quantity supports multiple jobs or prolonged use without frequent restocking.

Suitable for

• Grinding welds and seams on steel structures
• Deburring steel parts after cutting or machining
• Surface preparation prior to painting or coating
• Rust and scale removal from ferrous metal surfaces
• General metal fabrication and maintenance tasks

• Arbor hole: 22 mm
• Abrasive grit: K60 (ceramic Cubitron II)
• Backing type: fiber
• Recommended tool: 125 mm angle grinder
• Pack quantity: 25 discs
• Primary material application: steel / ferrous metals

How to use

Install the abrasive fiber disc onto a compatible 125 mm angle grinder with a 22 mm arbor, following the tool manufacturer's instructions for wheel mounting and safety guard positioning. Use appropriate rotational speed within the grinder's rated limits and apply moderate pressure; allow the disc's cut rate to do the work rather than forcing the tool. Maintain a consistent grinding angle and move the disc evenly across the workpiece to avoid gouging. Replace the disc when abrasive performance declines or if the backing shows signs of damage.

Usage recommendations

Always use suitable personal protective equipment: safety glasses or face shield, gloves, hearing protection and appropriate respiratory protection for metal dust. Verify grinder speed compatibility with the disc rating and ensure the work area is secure. For best results on steel, keep the disc moving to prevent overheating and check periodically for loading; use a cleaner or dressing method compatible with fiber-backed abrasives if clogging occurs.
