Highlights
Finish reduction on a variety of hard materials
Hook and loop attachment maximizes productivity
Micron-graded diamond mineral delivers a range of surface finishes and stock removal
Polyester film backing is durable, and can be run with coolant
Designed with a durable polyester film backing and diamond mineral, 3M Hookit Diamond Microfinishing Film Disc 675L provides fast finish reduction on hard materials including thermal spray coatings, ceramics, carbides, chilled iron, granite and others. A hook-and-loop attachment system makes attachment swift and simple.
High-Performance Abrasives for High-Performance Parts
We engineered the 3M Hookit Diamond Microfinishing Film Disc 675L with micron-graded diamonds on a 5 and 6 mil polyester film backing to be effective on hard-to-grind materials.
The automotive and aerospace industries in particular are embracing these materials and driving the demand for greater manufacturing efficiencies and increasingly critical tolerances.
3M Hookit Diamond Microfinishing Film Discs 675L is available in grades 125 and 74 micron to refine surfaces and 45, 30, 20 and 9 micron for finer finishes. We offer the disc in a range of grades, so operators can choose a disc that's tailored to their unique project needs.
Polyester-Backed Diamond Abrasive May Be Run Wet or Dry
The uniform caliper of this polyester film backing supports both uniform finishes and aggressive cut rates. It is tear-resistant and non-compressible.
The polyester backing is water-resistant, as well, so the disc may be run with coolant if desired. Coolant is a desirable component for diamond polishing, since it efficiently cools both the work and the abrasive. Adding a lubricant like water can help keep this disc running cool and extend abrasive life.
Focus On the Task, Not the Tooling, With Hookit
Our 3M Hookit hook-and-loop attachment system allows the operator to focus more on the task and less on tooling. 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 during use. Sanding, finishing and surface conditioning products with the hook-and-loop attachment and removal system are efficient for working through multi-step finishing processes. Abrasive products with a Hookit attachments can be used again and again for the life of the abrasive, unlike pressure-sensitive adhesive attachments.
