3M 7100064179 Cubitron Ii Hookit Film Disc 5 in 220 Grit

Product Description

The 3M 7100064179 is a coated abrasive disc featuring 3M Precision Shaped Ceramic Grain technology on a film backing. The triangular ceramic mineral is engineered to slice through material rather than gouge or plow like conventional abrasives, delivering cut rates up to two times faster and service life up to six times longer than standard abrasive discs. At 5 inches in diameter and 220 grit, this disc is built for aggressive stock removal on a range of substrates. The hook-and-loop attachment system allows fast disc changes without tools. Licensed tradespeople and finishing technicians use this disc in production and repair environments where throughput and consistency matter.

The 775L disc is suited for stock removal tasks on metal, composites, and similar substrates in both production shop and field repair settings. The film backing provides superior tear resistance and edge retention compared to paper-backed alternatives, making it a reliable choice for high-cycle applications. It is sold individually and fits standard 5-inch hook-and-loop backup pads common in metal fabrication, weld blending, and surface preparation work.

Installation Notes

Installation is performed by pressing the hook-and-loop face of the disc firmly onto a compatible 5-inch backup pad mounted on a random orbital or right-angle grinder. Ensure the grinder RPM rating meets or exceeds the disc RPM rating before use. Inspect the disc and backup pad for wear or damage before each use and replace if deterioration is observed. Follow all applicable shop safety protocols including eye and face protection when operating grinding equipment.
