3M™ Flexible Diamond Heavy Duty QRS Cloth Sheet 6022J, M250, Pattern 21, Green, 2-3/4 in x 5 in

3M Flexible Diamond products, including 3M™ Flexible Diamond Heavy Duty QRS Cloth Sheet 6022J, are 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 diamond mineral to a premium flexible backing in an open dot pattern. This provides durability and long life, while allowing the abrasive to conform to a variety of contours. In addition, the open dot pattern produces aggressive cutting action while reducing loading.

3M™ Flexible Diamond Heavy Duty QRS Cloth Sheet 6022J is commonly used for a variety of hard-to-grind materials. it's uniquely suited for contour finishing, because the backing is flexible.

Additionally, 3M equipped this diamond abrasive with a QRS (hook and loop) backing to allow for easier abrasive to tool attachment. A series of loops are formed by pulling tufts of material through the scrim backing. Subsequently, these loops attach to hooks on the holder pad (sold separately). The QRS backing allows for swift and easy change-out of discs, especially when there are multiple discs in a sequence.

3M™ Flexible Diamond Heavy Duty QRS Cloth Sheet 6022J 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. 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. Generally, larger dot patterns are more aggressive and will perform better in stock removal applications, whereas the smaller dot patterns will produce finer finishes, grade for grade.
