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. 3M™ Roloc™ System for Easy Power Tool Attachment. This disc features the 3M™ Roloc™ quick-change attachment system, allowing operators to easily swap between discs in multi-step processes. It also makes for quick power tool attachment, helping enhance productivity and throughput. To attach the disc, operators simply attach it to a Roloc™ backup pad (sold separately) and attach the backup pad to the power tool.
