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.
