I came across this article and however helpful, My SW2018 doesn't have larger than 3" in the Hole wizard for Pipe threads.

National Pipe Thread Taper or NPT threaded pipes and fittings are deployed in a variety of fields where transportation or containment of liquids, gases, steam, or hydraulic fluid is required. The NPT geometry allows internal and external thread surfaces to further engage when torque is applied to the thread assembly. This creates a fluid-tight seal. With NPT, as opposed to NPTF, the use of a sealing compound or tape is typically applied to the threads to complete the seal. Because of NPT’s mating and sealing capabilities, a practical knowledge of the NPT thread is a valuable addition to an engineer’s toolbox.

1 8 Npt Tap? - Toolsweek What Size Drill Bit for 1 8 Npt Tap? - Toolsweek

Taper of Thread: The taper on all NPT Thread is 1 in 16, or 0.75” per 1 foot, with the center line bisecting the angle created. The corresponding half-angle of the taper relative to the center line is 1 degree, 47 minutes or 1.79°. Take breaks occasionally to let your drill bit cool down as you drill. This is especially important if you’re using a high-speed drill. Now, before drilling, mark the spot where you want your hole. That way, you know exactly where your drill is going, and you minimize any errors. Plus, it keeps everything looking neat!I recommend high-speed steel taps if you’re looking for something with a bit more oomph. These are specifically designed for fast cutting and feature excellent wear resistance. Pitch, P: Corresponding to the Threads per Inch of the given pipe, e.g. this 1-1/2 NPT Pipe Size at 11-1/2 Threads per Inch will have a pitch of 1÷11-1/2 or .087. The angle between the sides of the thread is 60° when measured with a line bisecting the angle, perpendicular to the center axis. This creates a lead-in chamfer at the end of the thread. This is a result of the chamfer on the die during fabrication, which creates imperfect threads at the and of the thread.
