For a 1" mic I wouldn't spend the money. If it reads zero in the closed position then it's adjusted well enough. If you plan on buying more mics in the future, the 1-2" mic will likely come with a 1" standard.
Bullets from the major manufacturers are most always within a couple of tenths of the size stated on the box. You can do a cursory midrange check this way.
I don't want to sound contrary here but drill rod may not be your best cheap way to check a mic, it is sold in the unhardened state and easily bent, dinged and nicked. A drill blank is a much better choice, it is sold in the hardened state.
Used standards and gage blocks should be readily available at any used tool store and most hock shops. Mics, indicators, and gage blocks are the amongst the items commonly pilfered from machining company tool cribs.
