3M Hookit™ 366L 5 in Aluminum Oxide Micro Finishing Hook and Loop Abrasive Disc

3M™ Hookit™ microfinishing film disc 366L is rated best in the 3M™ microfinishing 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.
