Hi I'm building a all steel cnc router and looking at spindle motors, I see most of you have the 2.2 kW water cooled spindle.
I see now that there is a 3.0 kW water cooled spindle available on eBay for a little bit more money ,
I want to cut aluminium with my machine is it worth upgrading to the 3.0 kW
Spindle,

Thanks Paul
