MSI Diamond Spot Discs are manufactured by 3M. They are a micron graded metal bond product with “diamond spots” bonded through a synthetic woven mesh backing. This bonding method provides an aggressive, very long lasting product. Diamond Spot Discs have proven effective on hard and mixed hardness material including tungsten carbide, ceramics, hardened metals, silicon whisker composites and petrographic samples. This pressure sensitive adhesive (PSA) backed product provides very good flatness and no soft particle pull-out.
