My understanding is the taper is the same, but the drive dogs and
retention knob

one to the

Jon

and the draw bolt has a different thread and size. Some are metric

Since he has a Quick Change NMTB30 spindle with a retention collar
instead of a drawbar, can he use BT30 in the spindle with a suitable
BT30 drawbar, or will the Quick Change collar get in the way?
