Hookit™ 7000000297 Microfinishing Film Disc, 3 in Dia Disc, 30 micron Grit, Extra Fine Grade, Aluminum Oxide Abrasive, Polyester Film Backing

3M™ Hookit™ microfinishing film disc 268L is designed to enable operators to achieve precise, controlled, close tolerance finishes on surfaces from metals to plastics to wood. This product features precision, micron-graded aluminum oxide, resin-bonded to a high-strength, resilient polyester film backing. Aluminum oxide is desirable among industrial professionals for its fast cut rate and long life. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys. It cuts aggressively without significantly altering part geometry, which is great for applications like finishing and paint prep - when you want to maintain the part's original shape.
