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

Durability and Long Life
3M Roloc Diamond Cloth Disc 674W lasts longer and delivers a faster, more consistent cut compared to flexible metal bond diamond sanding discs. It also generally provides a more consistent finish on ceramics, carbides and hard coated materials.

Run it Wet or Dry
While it can be run dry, you can achieve optimum results by using this diamond disc with a coolant. Water is desirable when grinding or polishing with diamond abrasives, as it generally extends the abrasive life. It can also be used with oil- and water-based lubricants for lower grinding temperatures.
