I° case : I have think if leaves a original motor ,I will change only the spindle same diameter 10mm but have a ER11 chuck for drill up to 7mm.
II° case, if I will replacement motor original with a bushless power up to 400-500Watt, I need increase the diameter spindle because the new bushless motor have more power..
