3M 7100145407 Cubitron Ii Hookit 775L Film Disc 240 Grit 6 in

Product Description

The 3M 7100145407 is a 6-inch hook-and-loop abrasive film disc designed for aggressive stock removal on a wide range of substrates. Built on the Cubitron II 775L platform, it uses 3M Precision Shaped Grain technology, where triangular ceramic mineral grains are engineered 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. The film backing adds tear resistance and supports consistent edge retention throughout the disc life. Grit is 240, suited for finishing and final stock removal passes.

This disc is used in metal fabrication, woodworking, and composite finishing applications where fast material removal and extended disc life reduce downtime and changeover frequency. The hook-and-loop attachment system allows fast disc swaps without tools, making it practical in high-throughput production environments or fieldwork. It is sold individually and fits standard 6-inch hook-and-loop backup pads.
