The 3M Cubitron II Hookit Paper Disc is engineered with 3M precision-shaped ceramic grain, delivering exceptional cutting speed and durability. Unlike conventional abrasives that tend to "plough" through materials, the triangular-shaped ceramic mineral slices cleanly, ensuring up to 2x faster cutting and up to 4x longer life. Featuring a hook-and-loop attachment system, these Hookit discs allow for quick and secure disc changes while preventing contamination from dust or dirt--making them ideal for workshop and industrial environments. They also offer a finer finish compared to adhesive-backed discs, making them an excellent choice for blending, finishing, and general sanding applications.
