    Our 3M™ Hookit™ Blue Abrasive Disc 321U delivers best-in-class performance at every stage of paint prep and body repair. Premium aluminium oxide mineral abrasive is blended with ceramic grain for a full range of automotive sanding applications. Specially-designed multi-hole pattern reduces loading, extends disc life and aligns with most backup pads. Hookit™ attachment makes disc changes easy.

    Best-in-class value leaves the competition in the dust — literally. Multi-hole Discs are specially designed to improve anti-loading and boost dust extraction for improved productivity and a cleaner work environment. The multi-hole pattern captures dust, keeping the abrasive open for a faster cut and consistent performance throughout the life of the disc. 3M Blue Abrasives are your go-to workhrose for the entire shop. 3M’s engineered ceramic mineral blend delivers best-in-class cut and life. An anti-loading design and the available universal multi-hole pattern extend the life of the abrasive for consistent performance. A full line of discs is available in an array of grades for use throughout the repair process. Available in the 3M™ Hookit™ attachment system — from body repair to paint prep, BLUE is all you need.
