3M Hookit Microfinishing Film Disc 268L, 20 Mic 3MIL, Type D, 3 in x 7/8 in, Die 300M,

Achieve Close-Tolerance Finishes3M™ 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.Available in a wide range of grades, these discs are color coded for easy selection of grit and reduced risk of error. Run Wet or DryThese 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. Focus on the Task, Not the Tool with Hookit™ AttachmentMicrofinishing 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.
