GlowShift 1/8 NPT Drill and Tap Kit

Product Information

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. 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. 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.

Width of Flat, F: Width of the flat caused by truncation, or shortening of the thread crest or root. 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. 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.Create a Sketch on the Right Plane which intersects the helix created. On this sketch we will define the thread profile. 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.

These coatings can get a little pricey, but trust me; they’re worth it if you want to up your game. 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! 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. Drilling and tapping might initially seem intimidating, but it can be a breeze with the right tools. 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.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. 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. 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. 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. 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.
