3M 7100199422 Hookit 321U Disc 6 Inch 80 Grit Ceramic Ao

Product Description

The 3M 7100199422 is a 6-inch hook-and-loop abrasive disc from the 321U series, designed for automotive paint prep and body repair. It combines a ceramic aluminum oxide mineral blend to balance cut rate and disc life across multiple sanding stages. The 80-grit designation makes it well-suited for material removal, surface leveling, and coating prep work. An anti-loading coating keeps the cutting surface clear of dust and debris, and upgraded resin bonds extend durability through demanding work cycles. Licensed automotive body technicians and paint prep specialists are the primary installers of this product.

This disc is built for professional automotive refinishing environments, covering tasks from initial stock removal through final surface prep before primer or topcoat application. The multi-hole pattern is engineered to align with most standard backup pads and maximize dust extraction when used with a vacuum-ready random orbital or disc sander. The Hookit attachment system allows fast disc swaps without tools, reducing downtime during high-volume production work in body shops and collision repair facilities.
