High-Quality Materials for Microfinishing
Our 3M™ Diamond Microfinishing Film Sheet 675L and its family of discs, belts, etc., was designed to improve productivity and reduce the cost of superfinishing hard materials such as thermal spray coatings, ceramics, carbides, chilled iron, granite and others. It features micron-graded diamond mineral.

Get Best Results with Water
The uniform caliper of this polyester film backing supports both uniform finishes and aggressive cut rates. It is tear-resistant and non-compressible. The sheet is also water-resistant and may be used for wet or dry applications. Water is desirable for diamond polishing, since it cools both the work and the abrasive. Adding a lubricant like water can help keep the abrasive cutting and remove swarf.

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.
