No. 0.0005" is all the resolution you need for general lathe and mill
work.

I'm wanting a dial indicator for general use in a home workshop - setting
up
in a small 3.5" lathe etc.

One I'm considering has a resolution of 0.01mm/0.0005" with an accuracy of
0.02mm, For twice the cost I can get 0.003mm accuracy but do I need it?
