I've never been able to get G-wizard to give me good numbers on a Tormach, it just doesn't have the coolant flow or rigidity needed to get those numbers. Stick to .050" deep, and adjust your cutting feed as necessary to not break tools/give a good finish.

The tormach is decently powerful and rigid... imho I run one at the makerspace and for the team:
This is just an example of what is possible with the right tooling.

I've had good luck with GWiz but it takes some tunng to get to run right. Personally with my 1/4 2 flute tools .1-.15 DOC is not a problem.
The basic advice I can give for setting up something like this is, start small and buy tools as you need them and then it's highly recommended you have an "expert" around to help you setup and get comfortable running the machine. the TTS is a good way to go, the basic kits should hold you over with most of the tool holders you need. I also would not buy tools from McMaster-Carr due to pricing.
Also Cory from 254 has some really good posts about tooling setups if you dig into his post history a little.
