The R drill bit corresponds to a size of 0.339 inches or 8.61 mm. The pitch is calculated by measuring the distance between the first and second tooth. NPT threads are designed with a 60 degree thread angle, and are used for joining and sealing pipe to fittings in low pressure air or liquids and also mechanical applications. Note that in NPT threads, roots and crests of the thread are truncated with a square flat. When using L1 gauges to check threads, the thread is within permissible tolerance if the ring gauge face, or plug gauge notch, is +/- 1 turn from being flush with the end of the thread. <br> <br>Specification: - 1/2 Inch thread size; <br . The taper rate for all NPT threads is 1/16 ( inch per foot) measured by the change of diameter (of the pipe thread) over distance. Size All NPTs have tapered threads at a rate of 1/16.
