3M™ Hookit™ Discs:
A complete line of hook-and-loop style 3M™ Hookit™ discs is available for workspaces where adhesive-backed discs may become contaminated by dust or dirt. Hookit™ discs are often used in applications where a 3M™ Stikit™ disc may be too aggressive, as they tend to leave finer finishes than adhesive-backed discs. 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.
