3M™ Green Corps™ Hookit™ Disc, 00522, 8 in, 60, 25 discs per carton, 5 cartons per case

Built to withstand the most demanding auto body sanding jobs, the 3M™ Green Corps™ Hookit™ Abrasive Disc 255U is designed with heat-resistant resin bonding. The Hookit™ attachment system allows for quick disc changes during multi-step sanding processes.

The open coat construction of the disc ensures that abrasive grains are spaced apart, allowing dust and debris to collect in the spaces instead of loading the disc. This feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade, resulting in faster results. Some versions of the disc feature a 7- or 8-hole pattern that helps evacuate dust from the work surface, significantly increasing disc life and maximizing cut-rate.

The 3M™ Ceramic Abrasive Grain is a ceramic mineral designed using a 3M process to enhance the toughness and hardness of the grain. The 3M™ Green Corps™ Hookit™ 255U abrasive discs feature aluminum oxide blended with 3M™ Ceramic Abrasive Grain for one of the most durable and long-lasting abrasives available. Ceramic abrasives are engineered to cut fast and handle intense heat and stress, making them perfect for moderate to heavy stock removal, sanding, and finishing applications. The ceramic aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability, making this product an excellent choice for sanding metal, plastic, and fiberglass substrates, as well as finishing applications.

3M™ Hookit™ discs are ideal for workspaces where adhesive-backed discs may become contaminated by dust, dirt, or flying debris. They are often used in applications where a 3M™ Stikit™ disc may be too aggressive, as Hookit™ discs tend to leave finer finishes than adhesive-backed discs. Hookit™ sanding discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and be used again and again for the extent of the abrasive life.

The Green Corps™ Hookit™ Abrasive Disc 255U is built to last, from grain to backing to bonding to disc pad attachment. This disc is perfect for tough auto body sanding projects, providing top-quality sanding using fewer discs, which is just another way that auto body professionals can get the most from their operations.
