As stated in this thread light and fast is the key for the TM-1. I use a 2" inserted face mill. I run it at 1200rpm, which is right around the peak torque for this spindle. I also run a 3/4" insert endmill at 3050rpm, which keeps inside the top stock rpm. With these tools the limit to how deep you go is limited by the ridgitity of the machine not the spindle.
I have recently purchased a 1.25" high feed endmill. I run a .035 doc, with a .04 chip load. So that makes it 1300rpm and 100ipm. This was in 1045. The machine seems to handle the cutter well, and it works out to be about 3 X faster for hogging material than my 3/4" insert mill.
Good luck, and remember the tooling is more expensive than drugs...
