3M™ Hookit™ Paper Disc, 763U, P120, 5 in x NH (127 mm x NH)

The 3M™ Hookit™ Paper Disc 763U combines a blend of ceramic and aluminum oxide abrasive grain and a heavy F-weight paper backing to work well on tasks like repairing defects on metals, prepping for paint, and orbital sanding. The 3M™ Hookit™ Attachment System makes tool attachment swift and simple.

A blend of aluminum oxide and 3M Ceramic Abrasive Grain provides the 3M™ Hookit™ Paper Disc 763U with its fast cut and exceptional durability. Perfect for moderate to heavy stock removal as well as finishing, ceramic abrasives are engineered to handle intense heat and stress applications. Ceramic/aluminum oxide blends surpass aluminum oxide alone in cut-rate and durability and make an excellent choice for difficult grinding applications. Closed coat construction contributes to higher stock removal and longer life. It is great for final finishing and polishing on metal substrates as well, because the dense concentration of mineral lays down a finer pattern.
