Abrasive Flap Disc 3M Cubitron II 967A 125 mm x 22 mm Grit 40

3M Cubitron II 967A flap disc, 125 mm diameter with a 22 mm bore and P40 abrasive grit, is built for high-efficiency metalworking with angle grinders. The disc features 3M's Cubitron II ceramic grain engineered to deliver fast cutting, consistent stock removal and long life when working on steel and stainless steel. Its construction is suited to grinding, deburring and weld blending tasks in industrial and workshop environments where steady performance and predictable material removal are required.

Advantages

The Cubitron II ceramic grain provides micro-replicated triangular-shaped abrasive particles that cut faster and stay sharper longer than conventional abrasives, resulting in reduced cycle times and fewer disc changes. The flap design maintains consistent contact across the workpiece for even wear and smoother finishes. The 125 mm size and 22 mm bore make the disc compatible with a wide range of handheld angle grinders, and the P40 grit balances aggressive stock removal with surface control. Overall, the disc offers improved life, stability and efficiency for repetitive metal-preparation tasks.

How to use

Install the flap disc on a compatible angle grinder following the tool manufacturer's instructions and ensure the disc is mounted securely on the 22 mm arbor. Wear appropriate personal protective equipment, including eye protection, gloves and hearing protection. Start the grinder and apply moderate, even pressure to the workpiece while keeping the disc at the correct angle for the intended operation. Avoid excessive force which can reduce disc life and increase heat; let the abrasive do the cutting. Periodically inspect the disc for wear or damage and replace it when the abrasive is worn or the disc integrity is compromised.

Recommendations

Use the disc primarily on carbon steel and stainless steel for best results. For welding applications, move along the seam with steady strokes to achieve uniform blending. Maintain consistent feed and avoid dwell in one spot to prevent overheating and discoloration. Store the discs in a dry environment away from extreme temperatures to preserve performance and shelf life.
