My personal rule for bits 1/4" and smaller, is cut depth = tool diameter, unless the machine is not rigid enough. In some cases you can cut deeper. Your machine will likely flex way before the tool does.
I've accidentally cut corian with a 1/16" bit using a 1/4" depth of cut, with no problems. Chip evacuation is a bigger concern with smaller bits.
As for whether or not your spindle has enough power, you'll need to try it and see. Does your control software have a feedrate override feature, where you can adjust the speed while cutting?
