Product Information: 3M™ Diamond Cloth Disc 674W grinds and polishes hard-to-grind materials, providing long lasting, consistent results. Diamond mineral is resin-bonded to a durable, water-resistant cloth backing for dry use or use with coolants. Use this diamond disc on ceramics, carbides and hard coated materials..

Longer-Lasting, Keeps on Cutting
In 120 and 220 mesh grades, our 3M™ Diamond Cloth Disc 674W provides long-lasting cutting performance when used for finishing ceramics, carbides and hard coated materials.

Compared to flexible metal bond diamond sanding discs, 3M Diamond Cloth Discs 674W last longer and deliver a faster, more consistent cut. They generally will provide more consistent finishes as well.

Use Wet for a Finer Finish and Longer Abrasive Life
While it can be run dry, you can achieve optimum results using this diamond disc with a coolant. Water is desirable when grinding or polishing with diamond abrasives, as it generally extends the abrasive life. And it can be used with oil- and water-based lubricants for lower grinding temperatures.

Recommended Applications
3M™ Diamond Cloth Disc 674W is an excellent choice for finishing and dimensioning a variety of hard-to-grind materials, including tungsten carbide and chrome carbide, thermal sprays, yttria-stabilized zirconia and alumina ceramics, and carbon fiber epoxy composites.

It also easily removes coating oversprays and coatings prior to part refurbishment.
