Hookit™ Abrasive Disc, NH, 20 um, Aluminum Oxide, Hook and Loop, Film, 5 in Dia, Red, 20 Grit

3M™ Hookit™ micro finishing film disc 366L is rated best-in-the 3M™ micro finishing line of film backed discs. It features premium, micron-graded aluminum oxide abrasive bonded to a durable polyester film backing to produce a fast cut rate and uniform finish on wood, solid surface composites, plastic, fiberglass, paint prep, coating and corrosion removal, primer, e-coat or metal. We gave these discs a load-resistant coating to increase efficiency and product life by minimizing loading. The abrasive is resin bonded and supports disc flexibility without sacrificing durability and reliable performance under high heat and pressure. To complement the effective abrasive action, the polyester film backing flexes to help achieve a consistent finish over contours and offers greater tear resistance than comparable paper products, making it ideal for high production environments. And the 3M™ Hookit™ attachment and removal system holds the disc securely during use and provides easy disc change out. Designed for use with orbital and random orbital sanders, this disc comes in a range of grades for complete multi-step sanding and finishing.
