GlowShift 1/8 NPT Drill and Tap Kit

Product Information

For other types of tapered threads such as Aeronautical National External Threads, ANPT, the end must be chamfered 45° with a specified depth define in the ASE AS71051 Standard.

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. 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. With this sketch falling on the origin, normal to the central axis, draw a C ircle concentric to the origin with a diameter equal to the outer diameter of the pipe.External Thread Overall Length, L4: Total length of the external threads, included incomplete threads, or longer just as long as the total thread length is covered. These coatings can get a little pricey, but trust me; they’re worth it if you want to up your game.

1/8 Pipe Size Taps | McMaster-Carr

In this example, we are modeling a standard pipe, 1-1/2 NPT Pipe Size, at 11-1/2 Threads per Inch. We will use specific points on this reference sketch to define our pipe. Create another Sketch on the rear face of the thread and Extrude another circle equal to the outer diameter of the pipe to the third point on the reference sketch. First up, we have the trusty old steel taps. These bad boys are a reliable option for those on a budget but remember that they might not be the best choice for heavy-duty or precision work. I hope this information was useful and will hopefully come in handy for those of you looking for the answer!But wait, there’s more! Although finding the correct drill bit size for a 1/8″ NPT tap may seem challenging, it’s all about having the right resources, like tap drill charts. Taps could have various coatings like TiN (titanium nitride) or TiCN (titanium carbonitride), enhancing their performance and longevity. I cannot stress enough how important it is to lubricate when drilling! Trust me, lubrication prevents overheating, reduces friction, and helps prolong the life of your drill and tap. So don’t skimp on the lube! The 1/8″ NPT tap’s diameter is not 0.125 inches, but based on the thread on the end of a 1/8-inch pipe, it’s approximately0.405 inchesin the “big” diameter. 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.
