FAQ:

Q: What size is a drill bit?

A: Typically, drill bits are marked with their size above the threads on the shank. These markings are stamped into the metal and may read ¼-inch, 3/6-inch, or 25/32-inch.

Q: What is a standard drill bit?

A: Let the drill bit cool off after you have finished your project. Wipe the drill and drill bit with a clean,dry towel or cleaning cloth. Use a clean,dry toothbrush to brush off any shavings or other debris that may cling to the tool. Apply machine oil lightly with a paper towel or microfiber cloth. …

Q: What size drill bit for 1 4 NC 20 tap?

A: The best size drill bit for a 1/4″ 20 tap is a #7 if you’re using 75% thread or a 7/32″ if you’re using 50% thread. I’ve seen some people suggest a 13/64″ bit for the 50% thread instead, and that also works. Getting a little more precision when working with hard materials isn’t a bad thing.

Q: What is 40 mm NB pipe?

A: The nominal bore is the hollow section of the pipe. Nominal refers to the approximate measurement of the bore. Pipe was originally measured in inches. 100NB pipe works out to be exactly 4.5 inches (4.5 (inches) x 25.4 (mm/inch) = 114.3mm). That is why the outside diameter can’t be simple number like 100mm.
