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.

Trusted 3M Cubitron II

The 3M Cubitron II PSA Cloth Disc 784F is built for heavy-duty sanding on fabricated metals. This model stands out for its durability and precision, making it a reliable choice for tough jobs.

Its unique design with 3M Precision-Shaped Grain ensures a longer life and faster cut compared to traditional aluminum oxide discs. This disc is engineered to keep working efficiently through demanding tasks.

Flexible YF-Weight Backing

This disc features a 36+ YF-weight cloth backing that offers moderate flexibility. This backing allows the disc to conform well to both straight and contoured surfaces, improving sanding quality.

Such flexibility is ideal for grinding and blending applications where surface shape varies, ensuring consistent results across different metal parts and shapes.

Precise 5 Inch Size

The disc measures 5 inches in diameter with a NH arbor hole, fitting many common sanding tools. This size balances surface coverage and control for medium-pressure sanding tasks.

Its linered design with a tab and die 500X format supports easy handling and quick disc changes, helping maintain workflow without unnecessary interruptions.

Pressure Sensitive Adhesive

The PSA backing system sticks securely to compatible backup pads and removes cleanly when finished. This feature simplifies disc changes and reduces downtime during sanding operations.

With a high-strength adhesive, the disc stays firmly in place even under medium-to-high pressure, making it suitable for finishing, weld removal, and de-flashing tasks.

Large 200 Disc Pack

This product comes in a case of 200 discs, providing ample supply for extended projects or multiple users. The bulk packaging helps reduce frequent reordering and keeps costs manageable.

Having 25 discs per carton within the case also makes storage and inventory easier to manage, ensuring you always have the right number of discs on hand for your sanding needs.
