Disco abrasivo de fibra 3M Cubitron II 115 x 22 mm, grano 60+, pack de 25

3M Cubitron II abrasive fiber discs, size 115 x 22 mm with grit 60+, are engineered for high-performance grinding and rapid material removal on steel and stainless steel. The discs incorporate 3M’s triangular ceramic grain technology that maintains sharp cutting edges, delivering consistent cut rate and extended abrasive life. Supplied in a pack of 25, these fiber discs fit angle grinders with a 22 mm central arbor and are intended for tasks such as weld blending, deburring and general surface preparation in workshop and industrial environments.

Advantages

These abrasive fiber discs offer faster stock removal and longer life compared with conventional abrasives because of the self-sharpening triangular grain structure. The open-coated construction reduces loading on stainless surfaces and helps maintain cutting efficiency. The discs provide stable performance at typical angle grinder speeds and resist glazing, which reduces downtime for disc changes and increases productivity in repetitive metalworking tasks.

Suitable for

• Weld blending and smoothing welded seams on carbon steel and stainless steel
• Deburring edges after cutting or machining
• Surface preparation before painting, coating or welding
• General stock removal and shaping of metal components
• Workshop and light industrial grinding applications

Key specifications

• Disc diameter: 115 mm
• Arbor hole: 22 mm
• Abrasive grit: 60+ (medium-coarse)
• Construction: fiber backing with ceramic triangular (Cubitron II) grain
• Pack quantity: 25 discs

How to use

Securely mount the disc on an angle grinder with a compatible 22 mm arbor and ensure the grinder is powered off when fitting. Wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Start the grinder and apply moderate, even pressure to the workpiece, allowing the abrasive to do the cutting; avoid excessive force that can cause overheating or uneven wear. Keep the disc moving across the surface to prevent gouging and to achieve a uniform finish. Replace discs when the cutting performance noticeably decreases or if the disc shows damage.

Recommendations

Use these discs on clean, secure workpieces and match the grit grade to the required finish: use the 60+ grit for medium to heavy stock removal and initial surface preparation, then switch to finer grit abrasives if a smoother finish is needed. Store discs flat in a dry environment and inspect each disc before use for cracks or defects.
