I've read some reviews of the tool, where the user apparently had the -.002 tolerance upper, and was not able to fit the tool. My thought is that if you went with 0.998", it should still serve well, and keep the tool reasonably straight.
If you have the lathe, I would make two tools. One at 1.000" and another at 0.998" That way you have all your bases covered and will still have the tight tolerances to ensure a square face.
