Send me a 1.75" dia. drill and I will do the test for you .
That size means you need to run slow which could be below maximum spindle torque so you might have to go easy on the feed.
Is this is your first venture into CNC? I have found sometimes the mindset that carries over from manual machines has to be altered. On a manual machine you may choose to predrill a hole using a big drill because it can be quicker and easier than enlarging a small hole by boring but with a CNC the opposite can be the case because boring using one of the canned cycles is such a snap.
