The 1" drill capacity is from the Spec sheet for the X3 and was used as an example to say I don't want to give up low speed torque to gain high speed. I know how to circle cut with an end mill and do it routinely rather than make tool changes. Yes the X3 is still a small mill even though it is much larger than the X2.
I have seen references on the zone to a conversion to a 2hp 3phase VFD conversion and am trying to track it down. I would like to understand the pro's and Con's of this much power on the X3. Part of this comes from using CAM software developed for the bigger machines that expects to plow through at full cutting tool capability and assumes the power is available. On my X2 the spindle power was very much a limiting factor as steppers could feed fast enough to stall the spindle.
All of my 1/2" shank Silver and Demming bits mounted in 1/2" R8 collet are shorter than 1/4" bit mounted in a chuck, and faster to change bit sizes 1/2" to 33/32". So bit length is not a problem.

Reason: Annswer to bit length
