3M™ Hookit™ Microfinishing Film Disc 468L is ideal for sanding and finishing on plastics, wood, paint, e-coat composites, and metals. Made for Sanding and Finishing 3M designed the 3M™ Hookit™ Microfinishing Film Disc 468L with a hook and loop attachment system for sanding and finishing. It is intended to speed up disc swapping during multi-step sequences, thereby increasing productivity and throughput. 3M™ Hookit™ Attachment 3M offers a complete line of hook-and-loop style 3M™ Hookit™ discs for work spaces where adhesive backed discs may become contaminated by dust or dirt. Hookit™ sanding discs conveniently attach to a hook-and-loop backup disc pad (sold separately), can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life. The backup pad typically attaches to a tool like a random orbital sander (also sold separately). Silicon Carbide and Polyester Backing The 3M™ Hookit™ Microfinishing Film Disc 468L is engineered using micron-graded silicon carbide, which is a popular choice among industrial professionals because of its fast cut and smooth finish. Silicon carbide is a mineral that is very sharp and commonly used for low-pressure applications, such as sanding and finishing during paint prep. While it breaks down faster than aluminum oxide, this mineral produces a brighter finish and offers greater tear-resistance than comparable paper products, making it ideal for high-production environments.
