3M™ Diamond Cloth Disc 676W, 400 Mesh, Config

Designed for the Toughest Jobs3M™ Diamond Cloth Disc 676W is designed for grinding and polishing on particularly tough substrates like ceramics, composites and tungsten or chrome carbides. This abrasive also works well for stripping off thermal spray coatings during the refurbishment process.

This Diamond Cloth Can Take the Heat3M™ Diamond Cloth Disc 676W is used for polishing and finishing materials harder than 62 Rockwell C scale. To do this, it is engineered with micron-graded diamond grain, which cuts quickly through even the hardest substrates. With a heat-resistant resin bond and a heavy, Y-weight backing, it can stand up to aggressive use for long periods. And the water-resistant design allows for use with liquid coolants, which further reduce buildup from heat and debris. This can prevent the disc from loading and extend abrasive life.

• Abrasive disc used on hard substrates like ceramics, carbides and more
• Micron-graded diamond mineral for hard-to-grind materials
• Y-weight cloth backing offers excellent durability
• Resin bond withstands high grinding temperatures, extending the life of the abrasive
• Water-resistant construction allows use with coolant for extended abrasive life, but can also be run dry
