What size drill bit for 3/8 pipe tap?
Most drill charts recommend a 5/16 drill for a 3/8-16 bolt. Cutting holes that are smaller will leave more material for the tap to cut out, risking tap breakage. Drilling larger holes will result in weaker threads, increasing the possibility of stripping them.
What are the standard drill sizes?
Range 1 (R1) is shortest in length, more common for sizing production tubing or casing, and ranges from 18 to 22 ft. Range 2 (R2) is considered the standard length for drill pipe and ranges from 27 to 31 ft. Range 3 (R3) is common in casing and also deployed in deep water drilling applications.
How is NPT measured?
NPT is defined by ANSI/ASME standard B1.20.1. The taper rate for all NPT threads is 1 inch of diameter in 16 inches of length (3⁄4 inch per foot or 62.5 millimeters per meter) measured by the change of diameter (of the pipe thread) over distance of thread.
