  1. What is the size of the 3M™ Cubitron™ II PSA Cloth Disc, and how much does each case contain?

    The 3M™ Cubitron™ II PSA Cloth Disc comes in 6 inches x NH (no hole) with a Linered w/Tab. Each case contains 200 pieces.

  2. What is the weight of these discs and what kind of polishing application can it be used for?

    These discs are YF-weighted at greater than or equal to 50+. It is designed to work very well on hard metals such as carbon steel, nickel alloys, stainless steel and cobalt chrome applications requiring fine finishing and precision stock removal.

  3. Can you tell me about its durability considering it has so many backings?

    Absolutely! The backing material used in this disc was created particularly durable. Its non-woven design decreases loading which ensures that grain will stay sharper longer, enabling better air flow that promotes cooler running especially during radical stock removal operations which helps prolong product life.
