3M Hookit microfinishing film disc 268L is a fast cutting abrasive for precise, uniform, close tolerance finishes. An aluminum oxide mineral is resin-bonded to a 3 mil, high strength polyester film backing for durability. This disc is ideal for defect repair and leveling, paint prep and final finishing. 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. These film backed discs are water-resistant, so they can be run wet or dry. Coolant generally extends abrasive life, increases cut rate and prevents loading. The high strength, film backing maintains its strength and flexibility when paper will degrade when run wet, which makes it an excellent choice for use on a variety of woods and automotive applications. Microfinishing film 268L utilizes 3M Hookit hook-and-loop attachment system which allows the operator to focus more on the task and less on tool. 3M Hookit products are manufactured with loop material that attaches to a backup pad (sold separately) where tiny hooks firmly engage the loops. Attachment is quick, easy and secure. Sanding, finishing and surface conditioning products with the hook-and-loop attachment and removal system are efficient for working through multi-step finishing processes and are ideal for environments where dust and debris is common. Abrasive products with a Hookit attachment can be used again and again for the life of the abrasive, unlike pressure-sensitive adhesive attachments.
