Review on Mitutoyo 050103 Center Finder Diameter by Will Anderson

When I'm working on a pro milling machine, I use a good edge finder to find my part to within a tenth (0.0001") and when I pull back a Tenths, the edge of the finder returns to a smooth cylinder With that I have to step back a few thousandths before it goes straight The accuracy of the initial pitch I think is ok but I'd really like to be able to confirm this by stepping back and seeing that it has strayed from detail.It's fine for my CNC router but I wouldn't use it with a precision machine.
