3M Cubitron II Ceramic Sanding Disc 150mm 320+ Grade P320 Grit 775L 50 in pack

Attach the 3M Cubitron II Ceramic Sanding Disc (150 mm, P320 grit, 775L, MPN 47082) to a compatible angle grinder or sander to quickly clean and smooth metallic and composite surfaces. The disc uses 3M precision-shaped ceramic abrasive grain on a durable film backing and is supplied in a pack of 50. It is designed for high-speed rotary sanding (safe up to 10,000 rpm) and offers improved cut rate, even wear and long life compared with conventional ceramic discs.

Advantages

The precision-shaped ceramic grain delivers faster cutting and sustained sharpness while the film backing improves tear resistance and edge retention. The P320 grit provides a fine finish with a high particle count for even wear, extending disc life. The Hookit hook-and-loop attachment ensures a secure and quick change on a 150 mm backing pad. Overall, these discs reduce maintenance and replacement frequency and are effective across a wide range of materials.

How to use

Fit a compatible 150 mm Hookit backing pad (sold separately) to your angle grinder or sander, align the disc and press it onto the pad to secure the hook-and-loop connection. Operate the tool within the rated maximum speed (up to 10,000 rpm) and apply steady, even pressure while moving the disc across the workpiece to remove surface imperfections or achieve the desired finish. For heavy stock removal use a consistent motion and avoid concentrating on a single spot to prevent overheating or uneven wear.

Usage recommendations

Wear appropriate personal protective equipment including gloves, eye protection and respiratory protection when grinding or sanding metal and other materials. Ensure operators have received suitable training for angle grinder use and follow safety guidance relevant to the material being worked on.
