3M™ Diamond QRS Cloth Disc 674W grinds and polishes hard-to-grind materials, providing long-lasting, consistent results. Diamond mineral is bonded to a durable, water-resistant cloth backing for dry use or use with coolants. The QRS attachment system attaches firmly and makes this abrasive easy to change.
Use Wet for a Finer Finish and Longer Abrasive Life
While it can be run dry, you can achieve optimum results using the 3M™ Diamond QRS Cloth Disc 674W 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.
3M™ Diamond QRS 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.
