Fiber-schuurdisk 3M Cubitron II 115x22 mm, korrel 80+, 25-pack

3M Cubitron II abrasive fiber disc 115x22 mm, grit 80+, pack of 25 is a high-performance grinding disc engineered for metalworking applications on angle grinders. The disc features 115 mm diameter and a 22 mm bore for standard back-up pads and quick mounting. Designed to deliver rapid stock removal, consistent cut rate and extended abrasive life compared with conventional fiber discs, this product suits a range of surface preparation and finishing tasks on steel and other metals.

Advantages

The Cubitron II ceramic grain technology provides precise, fast cutting with reduced heat generation and fewer loading issues. The 80+ grit balances aggressive material removal with controlled surface finish, while the fiber backing ensures structural stability and durability under moderate pressure. Supplied in a pack of 25, the discs offer consistent performance across multiple workpieces and reduce downtime for frequent disc changes.

Suitable for

• Stock removal and shaping of steel and ferrous metals
• Weld blending and seam dressing
• Surface preparation before painting or coating
• Deburring and edge rounding
• General metal surface cleaning and rust removal

How to use

Mount the 115x22 mm disc securely on an appropriately rated angle grinder with a matching 22 mm arbor. Confirm the grinder’s maximum rpm and ensure the disc speed rating meets or exceeds that value. Hold the grinder with both hands, apply steady pressure and move the disc across the workpiece using smooth, overlapping strokes. Allow the abrasive to do the cutting—avoid excessive force that could reduce disc life or cause overheating. Replace discs when cutting efficiency decreases or when backing shows wear.

Recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection, gloves and respiratory protection as needed. Use with a compatible backing pad rated for fiber discs and ensure correct grinder rpm. Store discs flat and dry to maintain performance; avoid exposure to extreme humidity or direct sunlight.
