Im using the hole wizard to try and put in a 1/8" grease fitting in. the only option for pipe thread is "straight Pipe Tapped hole" with a size of 1/8"-27 NPSM and Im looking for 1/8" PTF can anyone help me with this please.
Hole type strait tap
Standard Ansi Inch
Type Straight pipe tapped hole
size 1/8"-27 NPSM
The tapered pipe tap should be the middle option in the hole wizard (in 2015 anyways) see below. The straight pipe tap would be under the tapped hole option one to the left. You would just have to change the drop down from bottoming tapped hole to straight pipe tap.
***EDIT***
I failed to notice that you had PTF thread. Only option I could think of is to use the NPT thread and just put it on a plane 1/27" off the surface you are trying to add it to.
