🪩 1 2 Npt Thread Drill Size

Thereare four unique tables on this Drill Tap Chart: DRILL SIZES – This table lists all drill sizes up to 1.000” and the most common from 1.000” up to 1.500” INCH TAP DRILL SIZES – This table lists the most common tap sizes, typically one coarse and one fine thread each, from a #0 to 1-1/2 Threadform per ANSI/ASME B1.20.1: NPTF: NATIONAL PIPE TAPER FOR FUEL: Thread form per SAE J476: NPSM: NATIONAL PIPE STRAIGHT MECHANICAL: Thread size refers to the nominal bore of the pipe. Subtract approximately 1/4”(6 mm) from thread measurement for nominal pipe size. Arule of thumb is that the right tap drill is around 85% for coarse threads and 90% for fine threads which feature a higher number of threads per axial distance. In our case, the correct tap drill would be the closest to 3.4 mm from below, and that is the 3.3 mm or 0.13-inch tap drill. Lower percentages such as “75% of the thread depth Thispage provided the thread dimensions of 2 - 11 1/2 NPTF. NPTF stands for National Pipe Thread Fuel, based on ASTM B1.20.3. It is also called Dryseal Pipe Thread. It is a variation of the more popular NPT thread standard based on ASTM B1.20.1. Learn more about NPTF and the difference between NPTF and NPT.

NPT taps are also called pipe taps, and don’t confuse them with NPTF taps and tapered taps like the ⅞- 9 tap. NPT taps can be carbon steel, HSS, or Interrupted thread NPT taps. Carbon steel NPT taps are generally used for cleaning or re-threading damaged or FUeQATU.
