trying to figure out a few problems here

if i am cutting into 200mm thick soft wood which is my maximum cutting height and cutting 3d that goes up to 150mm deep then that means the z axis plate and spindle is going to hit the material. i can counter act this by using longer tool bits and having the spindle lower. what is the longest tool bit you can get for 3d carving? i know a strong rigid machine is needed and strong motors.

thanks
