This only represents 10 microns (often less than tolerance call outs) but can be addressed with some fine diamond polishing paper between 8,000-12,000 grit. The operation is very smooth and these are great for measuring in channels or grooves or between features where an extension to the anvil would be helpful. Makes a great addition to the shop, take a look and see if they'll work for you!
