Mitsubishi makes some decent stuff . I love round inserts for their finish and the fact that they can be rotated a lot of times before they are toast .
You may not have a gear hob but thats going to beat the crap out of putting an indexer on a manual horizontal and cutting a tooth at a time
. Your definitely getting some solid machining out of that mill .
I'll be getting mine back into shape over the next while and plop it between my 440's . A recently purchased 1200w brushless dc should put the stock spindle motor to shame . The motor puts out 5600rpm and I only cut aluminum for the most part so I'll be gearing it for more rpm vs torque , as long as it will pull a 2" facemill at the higher rpm then I'll be happy . The 440's come with the mx3660 , so I'm going to follow the same lines and have a seamless transition to pathpilot
