drill bit size

Leroy · May 16, 2013

What size drill bit do I need to use for a standard 1/8" pipe thread grease fitting? Do have the tap that I have cleaned up threads with for years but never had to drill new hole.

11/32"

Lotsa times the drill size is stamped on the tap.

This tap is so old I don't think they thought of that at that time. It is at least 25 years old and at that time had never heard of the letter sizes or the descimal sizes.

Technically, a Q drill, but 11/32 will work just as well.
