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

Trusted 3M Cubitron II

The 3M Cubitron II PSA Cloth Disc 784F is a trusted choice for heavy-duty sanding. This model is designed to deliver durability and consistent performance on fabricated metals, making it ideal for tough jobs.

Featuring 3M’s Precision-Shaped Grain technology, this disc offers a faster, cleaner cut that lasts longer than traditional abrasives. Its advanced design helps reduce heat buildup, protecting your workpiece and extending disc life.

Precise Grade And Weight

This product comes in a 60+ YF-weight grade, providing a balance of strength and flexibility. The YF-weight cloth backing offers moderate flexibility, allowing the disc to conform well to both flat and contoured surfaces.

The 60+ grade ensures effective sanding on stainless and mild steel, making it suitable for applications like grind-mark refinement and light weld removal. This grade supports medium-pressure sanding tasks efficiently.

Optimal Size And Format

The disc measures 5 inches in diameter and features a NH (non-hole) format with a liner and tab for easy handling. This size is versatile for many metalworking tasks, providing good coverage and control.

The PSA (Pressure Sensitive Adhesive) backing allows quick and clean disc changes on compatible backup pads, reducing downtime. The liner protects the adhesive until use, ensuring strong attachment during sanding.

Convenient Pack Quantity

This product is sold in a case of 200 discs, organized as 25 discs per carton. This bulk packaging supports continuous work without frequent reordering, ideal for busy workshops or production environments.

Having a large pack count on hand means fewer interruptions and better inventory management. It’s perfect for professionals who need reliable supplies for ongoing metal finishing and de-flashing tasks.

Durable Backing And Adhesive

The 60+ YF-weight cloth backing is engineered for durability and flexibility, allowing the disc to handle grinding and blending on both straight and curved surfaces. This backing supports consistent sanding results.

The high-strength PSA backing sticks firmly to backup pads and peels off cleanly when replaced. This feature helps save time by minimizing disc change effort and reducing contamination, keeping your workflow smooth.
