Our 3M™ Hookit™ purple clean sanding abrasive disc 334U combines excellent dust removal and fast cutting, long-lasting abrasive for higher productivity and lower cycle times. A spiral pattern clears dust from the surface and reduces loading for longer disc life - up to 3X longer than traditional auto body abrasive discs. Our 3M™ Hookit™ attachment system makes disc change outs fast and easy.
