3M™ Flexible Diamond QRS Cloth Sheet, 6002J, M74, 2 1/4 in x 5 in (57.2 mm x 127 mm)

The 3M™ Flexible Diamond QRS Cloth Sheet 6002J was designed to tackle hard-to-grind materials like stone, glass, ceramic, metal, carbide, and composites. The sharp-cutting diamond mineral and flexible backing make this abrasive a good match for a variety of metalworking applications.The 3M Flexible Diamond QRS Cloth Sheet 6002J is designed to help you achieve improved finishes on a wide range of hard-to-grind materials without sacrificing cut rates. A metal bond securely anchors micron-graded diamonds to a premium flexible backing in an open dot pattern. This provides durability and long life, while allowing conformance to a variety of contours. In addition, the open dot pattern produces aggressive cutting action while reducing loading. The 3M Flexible Diamond QRS Cloth Sheet 6002J is commonly used for a variety of metalworking applications: finishing, polishing, grinding, and stock removal. It's uniquely suited for contour finishing, because the flexible backing enables the sheet to move forgivingly over the surface. The 3M Flexible Diamond QRS Cloth Sheet 6002J comes in three patterns:18, B2, and 21. Here's how to distinguish between the three. 18 is a small-dot pattern, designed for fine finishes. It provides the fastest stock removal on very hard materials such as thermal spray coatings and ceramics. B2 is a medium-dot pattern designed for aggressive cutting action and has improved coolant flow, given the spacing of the dots. 21 is the largest dot pattern and it's ideal for applications where loading is a problem; gaps allow swarf and debris to escape.
