3M™ Diamond QRS Cloth Sheet 658WY, 400 Mesh, 3 in x 4 in

Contour Finishing on Tough-to-Cut Materials
Designed for grinding and polishing, our 3M™ Diamond Polishing QRS Cloth Sheet 658WY can tackle tough materials including ceramics, carbides and cast iron. It also works well for stripping thermal spray coating during the refurbishment process. The flexible, J-weight cloth provides a durable, consistent backing for polishing on and around contoured surfaces. The cloth backing also features our Hook and Loop attachment system, which holds firm during use but allows for easy removal.

Hard to grind materials, such as thermal spray, ceramics and carbides, coupled with precise dimensional tolerances-driven by the automotive and aerospace industries are good reasons to opt for diamond Superabrasives when the substrate requires it.

The 3M™ Diamond QRS Cloth Sheet 658WY is available in the following mesh grades: 1800, 1200, 600, 400, 220, 120, 100 mesh

Run Wet for Finer Finish and Cooler Running
Optimum results are obtained when run wet. Coolant is a desirable when using Superabrasives since it efficiently cools both the work and the abrasive. Beyond its cooling properties, coolant will remove swarf and prolong abrasive life.

We equipped this diamond abrasive with a hook and loop backing to make for easier abrasive to tool attachment. A series of loops are formed by pulling tufts of materials through the scrim backing. Subsequently, these loops attach to hooks on the holder pad (sold separately). The hook and loop backing provides for swift and easy change-out of abrasives, especially when there are multiple abrasives in a sequence.

Recommended Applications
Quickly sand down concrete, granite, stone, glass, ceramics and carbides etc. Polish by hand with water for a better finish and to extend the life of the sheet.
