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.

An anti-loading design and the available universal multi-hole pattern extend the life of the abrasive for consistent performance.
