Abrasive Fiber Disc 3M Cubitron II 982C 180×22 mm, grit 36+ — pack of 25

Abrasive Fiber Disc 3M Cubitron II 982C 180×22 mm, grit 36+ — pack of 25 are high-performance fiber discs engineered for aggressive metal removal and reliable surface blending. The Cubitron II ceramic abrasive grain is shaped for consistent cutting edges that maintain sharpness during use, delivering fast material removal on angle grinders and portable grinding tools. These discs are intended for professional workshop and industrial environments where efficiency and disc life are important.

Advantages

These 3M Cubitron II fiber discs combine a ceramic mineral blend and a durable fiber backing to provide a balance of fast cut rate and extended wear. The shaped ceramic grain reduces loading and heat buildup, improving consistency across the disc life. The 180×22 mm size fits standard 7" angle grinders with a compatible arbor, while the open fiber construction supports coolant flow and chip clearance for smoother grinding on welds and heavy stock removal.

Suitable for

• Stock removal and shaping of steel and stainless steel
• Weld blending and preparation for finishing
• Surface preparation prior to painting or coating
• Deburring and chamfering metal edges
• High-volume workshop and industrial grinding tasks

Key specifications

• Disc diameter: 180 mm
• Arbor hole: 22 mm
• Abrasive type: shaped ceramic grain
• Grit: 36+ (coarse)
• Backing material: fiber backing
• Pack quantity: 25 discs
• Designed for use on angle grinders and portable grinding tools

How to use

Mount the disc on a compatible angle grinder with a 22 mm arbor, ensuring the grinder is disconnected from power during fitting. Confirm the disc is rated for the grinder's maximum RPM. Use appropriate personal protective equipment including eye protection, hearing protection and gloves. Apply steady, controlled pressure and maintain an appropriate contact angle to avoid overheating or glazing. Replace discs when wear, cracking, or reduced cutting performance is observed.

Usage recommendations

For optimal performance when grinding stainless steel or high-alloy materials, use moderate speed and short, intermittent passes to reduce heat buildup. Keep a consistent feed rate and allow the shaped ceramic grain to cut rather than forcing heavy pressure. Store discs flat in a dry environment to preserve backing integrity.
