3M 7100075208 Cubitron Ii 775L 5 Inch 180 Grit Abrasive Disc

Product Description

The 3M 7100075208 is the Cubitron II 775L coated abrasive film disc, engineered for high-speed stock removal on metal, composites, and other hard substrates. At 5 inches in diameter and 180 grit, this disc uses 3M Precision Shaped Grain technology, where triangular ceramic mineral tips are oriented to slice through material rather than plow or gouge like conventional abrasives. The result is a disc rated to cut up to 2 times faster and last up to 6 times longer than standard abrasive discs. Rated to 12,000 RPM. The Stikita hook-and-loop style backing allows fast disc changes without tools.

This disc is suited for finishing and stock removal applications in fabrication shops, metal service centers, and maintenance environments. The film backing provides greater tear resistance and edge retention compared to paper-backed alternatives, making it a reliable choice on contoured or irregular surfaces. Applications include weld blending, surface prep, and final finishing passes where consistent cut rate and disc longevity matter. It is primarily selected for ferrous and non-ferrous metal work, though the construction supports a broad range of substrates.

Installation Notes

Installation and disc changes should be performed with the grinder or sander fully powered off and unplugged. Confirm the backup pad is rated for Stikita attachment before mounting. Never exceed the 12,000 RPM speed rating marked on the disc. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or worn attachment backing.
