Chris,
With the best will in the world, I think that you'd be asking a great deal to produce a tool such as you have intimated in your drawing with the Grizzly – or any other such T&C grinder. I drew the proposed tool (to scale) and to my mind that is a minute size to aim for. You'll need a microscope as well! Look at this:

That's seriously small and I doubt it would last very long. What exactly are you trying to acheive? There's got to be an alternative way to get the desired effect.
I assume that, quoting Grizzly machines, you are located in North America. Those machines are available in various colours and flavours from a number of retailers at varying prices. All seem to do a pretty good job for what they intended to do. See Stefan Gotteswinter's sie and YouTube channel, for example.
I have no experience of them and not much experience of tool grinding in general, but someone who knows will doubtless be along soon to say I'm wrong and tell you how to do it!
