Abrasive Fiber Disc 3M Cubitron II 180 x 22 mm, grit 80+, pack of 25

Fiber abrasive discs 3M Cubitron II 180 x 22 mm, grit 80+, pack of 25 are engineered for demanding metalworking and industrial surface preparation tasks. These 180 mm discs with a 22 mm arbor hole use 3M's Cubitron II ceramic abrasive grain to deliver rapid material removal, consistent cutting performance and extended service life compared with conventional abrasives. Supplied in a pack of 25, they are intended for use on angle grinders and similar portable machines where stable, high-rate stock removal and predictable finishing are required.

Advantages

These fiber discs combine a precision-shaped ceramic grain and a robust fibre backing for improved cutting speed, reduced heat build-up and longer life. The 80+ grit strikes a balance between aggressive stock removal and the ability to achieve a controlled surface profile for subsequent finishing or coating. Uniform abrasive distribution supports repeatable results across multiple workpieces and reduces the need for frequent disc changes.

Suitable for

• Deburring of metal edges and components
• Weld blending and seam dressing
• Surface preparation before painting or coating
• Light shaping and edge breaking on steel and stainless steel
• Industrial maintenance and fabrication workshops

Key specifications

• Disc diameter: 180 mm
• Arbor hole diameter: 22 mm
• Abrasive type: ceramic precision-shaped grain (Cubitron II)
• Grit: 80+
• Backing material: reinforced fibre
• Pack quantity: 25 discs

How to use

Mount the 180 x 22 mm disc on a compatible angle grinder fitted with the correct backing pad and ensure the machine is disconnected from power while changing discs. Check the disc for visible damage before use and follow the grinder manufacturer's recommended safe operating speed. Apply steady, even pressure and keep the disc moving across the work surface to avoid localized overheating or gouging. Replace the disc when cutting performance declines or if backing or abrasive shows wear.

Recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and gloves. For stainless steel, use lower contact pressure and consistent motion to minimise heat and discoloration. Store discs flat in a dry area away from direct sunlight and extreme temperatures to maintain performance.
