I have a set of collets and 2.5mm is one of them. Drilling in aluminium it is important to spot drill first. I normally use a 6mm 90 degree spot drill for that purpose, and after spot drilling (not resetting the machine so that I keep the zero positions) I just change to the right bits and start the drilling. Just make sure the spindle can't start spinning when you are changing bits so that you are safe.
