3M™ Diamond QRS Cloth Sheet 658WY, 120 Mesh, 3 in x 9 in

• Micron-graded diamond for use on hard to grind materials
• Diamond has excellent thermal stability and wear resistance for long life relative to conventional abrasives
• Flexible, J-weight cloth backing is waterproof for use with coolant
• QRS attachment system minimizes downtime
• Available in grades 100mesh-1800mesh

A tough resin bond and waterproof backing on the 3M™ Diamond QRS Cloth Sheet 658WY is ideal for hard-to-grind substrates. Micron-graded diamond is affixed to a flexible J-weight cloth backing and a QRS Hook and Loop Attachment System makes tool attachment swift and simple.

Contour Finishing on Tough-to-Cut Materials
Designed for grinding and polishing, the 3M™ Diamond 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.

This diamond abrasive is equipped 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.
