3M ™ Hookit ™ Gold Film Disc 255L features aluminum oxide abrasive grain on a film backing for a fast cut-rate and uniform, close-tolerance finish on wood, paint prep and defect repair applications. Our flexible film backing provides a consistent finish and greater tear-resistance than a comparable paper product, making it well-suited for a high-production environment. Our 3M ™ Hookit ™ hook-and-loop attachment works well by enabling easy re-use when switching between grades before the discs are worn out. The open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade and the disc's load-resistant coating reduces clogging of the disc, making this a good choice for woodworking and other applications where loading hinders performance. Designed for use with a random orbital sander, this disc comes in a range of grades for fine sanding and finishing and is resin-bonded for reliable performance under high heat and pressure.
