TPI - Threads per Inch. B1.20.1 Standard on Pipe Threads, General Purpose, Inch. NPT - American National Standard Taper Pipe Thread. Note that both NPT and NPS have the same thread angle, shape, and pitch (threads per inch). However, NPT threads are tapered and NPS threads are straight (parallel).3. Set the compound rest at 29 degrees to the right for right hand threads. 4. Install a 60 degree threading tool bit and set the height to the lathe center point. 5. Set the tool bit and a right angles to the work, using a thread gage. Figure 5. Using the Center gage to position the tool for machining Threads. driver lan msixa
