Earlier Wongster said it'd be NPT without the taper. So probably just a standard thread.
Wongster, when cutting a thread that's really close to the chuck, and especially for internal threads no matter where they are, I put the tool on the opposite side of the work and run the machine in reverse to cut the threads. That way the end of the threading is the end of the workpiece and if you can't disengage the the lead screw, just let it keep going until it's far enough to out of the way to check the thread. Adding a threading dial would be helpful!
