Designed with a strong polyester film backing and sharp diamond mineral, the 3M™ Diamond Microfinishing Film Sheet 675L delivers fine finishes on hard metals like thermal spray coating, ceramics, carbides, chilled iron, and granite.
The 3M™ Diamond Microfinishing Film Sheet 675L securely anchors micron-graded diamonds to a polyester film backing. Polyester film backings are water-resistant, so the abrasive may be run with a water or oil-based lubricant, which helps wash away unwanted swarf and debris and keeps the abrasive running cool. The belt is also colour-coded by grade to help ensure you select the right grade for your job.
