3M Diamond Polishing QRS Cloth Disc 656WY, for grinding and polishing hard to grind materials such as ceramics and carbides, uses micron-graded diamond particles bonded to a flexible, J-weight waterproof cloth backing. A pressure-sensitive adhesive allows easy peel-and-stick tool attachment.

Tough Cutting Uniform Finish
Designed for grinding and polishing, our 3M™ Diamond Polishing QRS Cloth 656WY can tackle tough materials like ceramics, tungsten and chrome carbides and composites. 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.

This Diamond Cloth Can Take the Heat
This product is designed with diamond particles encapsulated in a ceramic bead and resin- bonded to a cloth backing, which helps these products be both cost-effective and long lasting. This product can also be used with oil and water based lubricants for lower grinding temperatures. Also, coolant will help remove swarf and prolong abrasive life.

Swift and Simple Attachment
The hook-and-loop backing makes disc attachment, removal, and re-attachment easy, and facilitates use and re-use of the disc for the full extent of its abrasive life. These discs have J-shaped hooks. These J-shaped hooks grip the brushed nylon loop backings of any hook-and-loop style backup pad. And while attaching them is easy, they provide a secure attachment mechanism for even the most heavy duty sanding.

Recommended Applications
Hard to finish materials, including thermal spray parts, ceramics, composites, HVOF coatings, chilled iron and non-ferrous metals.
