About this deal

These coatings can get a little pricey, but trust me; they’re worth it if you want to up your game. Create a Sketch on the Right Plane which intersects the helix created. On this sketch we will define the thread profile. Width of Flat, F: Width of the flat caused by truncation, or shortening of the thread crest or root. 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. Taps could have various coatings like TiN (titanium nitride) or TiCN (titanium carbonitride), enhancing their performance and longevity.

NPTHAND - National Pipe Taper Hand Taps - Drill Service

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.

Once we open up the Hole Wizard feature, select the Tapered Tap option in the Hole Type section. Set the standard to ANSI Inch, set Type to Tapered Tap Pipe Tap and in the hole specifications, select the desired size in inches.

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. Create a Sketch on the rear face of the extrusion and draw a circle equal to the outer diameter of the pipe. 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. 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.Now, for the drill bit size, the secret lies in subtracting the pitch of the thread from its diameter. For a 1/8″ NPT tap, the magic letter is anR-shaped drill bit. The angle between the sides of the thread is 60° when measured with a line bisecting the angle, perpendicular to the center axis. 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.

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. At the bottom of the PropertyManager of the Hole Thread, the text can be edited to any note and can be later automatically imported in the 2D drawing of the model. 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. 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. 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. If you’re working with a 1/8″ NPT tap, one of the key things you need to know is the correct drill bit size. So, let me clear that up for you! Create a S ketch on the rear face of the extrusion. Once again, draw a circle equal to the outer 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.
