GlowShift 1/8 NPT Drill and Tap Kit

Product Information

NPT is defined by ANSI/AMSE standard B1.20.1, and in this article we’ll be specifically referencing the ANSI/ASME B1.20.1-1983, including its charts and tables.

Choosing the right tap material is crucial for a successful tapping job, especially when working with a 1/8 NPT tap. So, let’s talk about the best materials to ensure you get it right the first time!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.

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! These values may also be acquired using the formulas contained in the ANSI/ASME B1.20.1. Note that the listed dimensions are in inches and are given to four or five decimal places only to avoid errors in computation, these do not indicate required precision. In NPT threads chamfers are not required, although a chamfer may be present, there are no specifications on the angle and depth of the chamfer. 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. First, you’ll want to ensure you got the right size drill bit. In our case, we need anR-shaped drill bit equivalent to 0.339 inches or 8.61 mm.Width of Flat, F: Width of the flat caused by truncation, or shortening of the thread crest or root. 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. Create a Sketch on the new face of this extrusion and draw a Circle equal to the inner diameter of the 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. Manufactured with precision ground flutes for producing accurate class 2 thread forms, with a medium fit tolerance. Sherwood Tap dimensions conform to ANSI 94.9.

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. Sizes and dimensions of pipes and tubes, and their fittings - inside and outside diameter, weight and more. To account for tolerance and precision during the fabrication of these threads, refer to guides such as this one, which explains how to use external and internal NPT thread gauges. These go-no-go gauges control quality of NPT threads during fabrication.NPT - National Pipe Taper 1:16 Hand Taps come in Second, Taper and Plug (also known as Bottom). ISO 2284 Hand taps with full thread profile for general purpose use. Available in HSSE as standard and M2 HSS on request. At Machining Doctor, our mission is to serve the machining industry as a comprehensive and reliable source of technical information. We strive to be the go-to destination for professionals in the niche seeking information, knowledge, and expertise. Join us and stay ahead of the curve! 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, commonly known just as NPT, is a U.S. standard for tapered threads used on threaded pipes and fittings. This standard is widely used all over North America. Pipe thread sizes are usually based on the inside diameter (ID) or flow size. The way to read an NPT size is the nominal inside diameter and the number of threads per inch. For example, if we have a 1/4-18 NPT, that means it is a 1/4 inch inside diameter and 18 threads per inch. If LH is added to the end, it means the pipe has a left-handed thread. I am faced with making an 5" aluminum pipe Cap on the CNC Mill, that I am not able to find locally. and not sure how to draw this or program this when it comes to cutting the threads. I will be thread milling. Not sure what diameter, depth of thread, taper angle, and depth of the actual thread to program. I do know that 5" is 8 TPI. So that part is clear. Any help appreciated.

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. Taps could have various coatings like TiN (titanium nitride) or TiCN (titanium carbonitride), enhancing their performance and longevity.
