Got you in other thread.

Good luck finding that size at your local hardware store. Depending on what your tapping, a 9/16" drillbit will do and it's way more common. It's 1/64" smaller in size. I did the math for you.;D

9/16 is what I used.

Its only a 1/16th difference and it is smaller. So it means you have to take 1/16" more material with the tap. I think it will be fine.

TY guys......

Are you relocating the ECT sensor on the Explorer coolant tubes? A 9/16" will work fine.
