Abrasive Fiber Disc 3M Cubitron II 115x22 mm, grit 60+, pack of 25

Fiber backing abrasive discs 3M Cubitron II 115 x 22 mm, grit 60+, pack of 25 are designed for high-performance grinding and surface preparation on metal, welded joints and other hard surfaces. The discs combine precision-shaped ceramic abrasive mineral with a resilient fiber backing to deliver consistent cut rates and extended service life. The 115 mm diameter and 22 mm centre hole make these discs suitable for use with common 4.5-inch angle grinders and compatible pneumatic tools when used with the appropriate backing pad.

Advantages

These Cubitron II fibre discs provide faster material removal and longer life than conventional abrasives due to the ceramic grain that fractures to form sharp points during use. The fibre backing keeps the disc stable under pressure, improving contact with irregular surfaces and welded seams. Packaged in sets of 25, the discs offer convenient bulk supply for workshop and site jobs, reducing downtime for frequent disc changes.

How to use

Fit the disc to a compatible backing pad with a 22 mm arbor hole and secure it on a 115 mm (4.5") angle grinder or an approved pneumatic tool. Start the tool at low speed to check for correct mounting and balance, then apply steady, even pressure while moving the disc across the workpiece. Allow the abrasive to do the cutting; avoid excessive force that can reduce life and increase heat. Replace the disc when wear reduces cutting performance or when the backing is damaged.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Match disc speed rating to the grinder's no-load speed and avoid exceeding the maximum RPM. For optimal performance on stainless steel, use light, consistent passes to minimise heat build-up and discoloration. Store discs flat in a dry environment away from direct sunlight and extreme temperatures.
