<prompt> Diamond finishing instruments use diamond particles of size:60 to 74 μm10 to 38 μm38 to 44 μm5 to 8 μm  <response>: Diamond particle size is commonly categorized as coarse 125 to 150 μm, medium 88 to 125 μm, fine 60 to 74 μm, and very fine 38 to 44 μm for diamond preparation instruments. Diamond finishing instruments use even finer diamonds 10 to 38 μm to produce relatively smooth surfaces for final finishing with diamond polishing pastes.Ref: Sturdevants art and science of operative dentistry. 4th edition page 338
