3M Cubitron II PSA Cloth Disc 784F is the most durable 3M PSA disc for heavy-duty sanding on common fabricated metals. It features 3M Precision-Shaped Grain, this disc delivers longer life and a faster, more consistent cut than aluminum oxide discs. Get your job done faster with 3M Precision-Shaped Grain. These precisely shaped, uniformly sized triangles of ceramic aluminum oxide are designed to fracture and self-sharpen as they wear, continuously forming new, super-sharp points and edges that slice cleanly through metal like a knife. This prevents heat from building up — helping to reduce heat-related stress cracks and discoloration. Additionally, because the abrasive itself stays cooler and sharper, disc life can increase significantly compared to other ceramic discs. PSA backing makes for easy disc changes. 3M Cubitron II PSA Cloth Disc 784F features a high-strength pressure sensitive adhesive attachment system, which is a good choice for high heat and medium-to-high-pressure sanding applications. Convenient liners reduce contamination of the adhesive, maximizing adherence to the disc pad. When the operator is finished with the disc, it peels off cleanly, leaving the disc pad ready for a new disc. Featured Applications Light weld removal Body in white Grind mark refinement Smoothing bent metal surfaces De-flashing composites Removing parting lines De-flashing sharp metal

Reliable 3M Cubitron II

The 3M Cubitron II PSA Cloth Disc 784F is built for durability and heavy-duty sanding. This model is designed to handle common fabricated metals with ease, making it a trusted choice for tough sanding jobs.

Featuring 3M’s most durable PSA disc technology, it delivers longer life and consistent performance. The 784F model ensures you get reliable results every time you work on metal surfaces.

Flexible YF-weight Backing

This disc uses a 50+ YF-weight cloth backing that offers moderate flexibility. This backing allows the disc to conform well to both straight and contoured surfaces, improving grinding and blending tasks.

The flexible backing makes it ideal for smoothing bent metal surfaces and refining grind marks. It adapts to the shape of your workpiece, enhancing control and finish quality.

Precise 5 Inch Size

The disc measures 5 inches in diameter with a NH arbor hole, fitting many standard sanding tools. This size is practical for a variety of metalworking applications, balancing coverage and maneuverability.

Its dimensions make it suitable for tasks like light weld removal and de-flashing composites. The 5-inch size ensures you can reach detailed areas without sacrificing sanding power.

Pressure Sensitive Adhesive

The PSA backing on this disc allows for quick and easy changes. It sticks firmly to compatible backup pads but removes cleanly without residue, saving time during sanding operations.

This feature supports medium-to-high-pressure sanding and helps reduce downtime. The linered design with a tab protects the adhesive until you’re ready to use the disc, maintaining strong adhesion.

Bulk Pack Convenience

This product comes in a case of 200 discs, organized as 25 discs per carton. Buying in bulk ensures you have plenty of discs on hand for continuous work without frequent reordering.

The large pack size is perfect for professional shops or production environments where disc changes are frequent. It helps maintain workflow efficiency and reduces supply interruptions.
