GlowShift 1/8 NPT Drill and Tap Kit

Product Information

Drilling and tapping might initially seem intimidating, but it can be a breeze with the right tools. 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. I hope this information was useful and will hopefully come in handy for those of you looking for the answer! 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. 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.

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.

Create a Sketch on the new face of this extrusion and draw a Circle equal to the inner diameter of the pipe. 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.

Overheating can cause the bit to wear out, break, or damage the material you’re drilling into. Taking a breather is a small effort that can make a huge difference!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! 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. The angle between the sides of the thread is 60° when measured with a line bisecting the angle, perpendicular to the center axis.

Create a Sketch on the Right Plane which intersects the helix created. On this sketch we will define the thread profile. 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.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. 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.
