i am drilling out my axle shafts. they are drilled for 5on4.5 and 5on5.5

but the 5on4.5 patern has 1/2" holes. the nug bolts i have will not fit in a 9/16" hole. the shoulder of the lug bolt is .604" and the splines on the lug bolt are .620" 9/16" is too small and 5/8" (.625")is too big.

therefore i need a 39/64" (.6094") drill bit.

I am picturing the splines on the bolt. Are they not a press fit so they fit really tight and not move around? Sure you don't need a 9/16" hole and a press to install the bolts? Isn't that the purpose of the splines?

Thats why i have the 39/64 bit in my tool box, I had to swap out the 1/2" lug holes in an eaton rear to the 9/16 studs. It is still a pound the studs in even with the slightly largder hole. With a 9/16 hole the shank of the stud wont even fit through the hole.


I think I bought mine at a tool store in boise. It was about $30.

Try Home Depot, or Lowes, even Ace Hardware if Sears dont have it.


Its a long drive for you, But pm me if all else fails, you can use mine.
Or I can bring it down to work with me on monday (UTA Frontrunner facility off of warm springs)

The lowes on 4500S. and 500W. has a good selection of bits. That store seems to have a better selection then any of the ones around me.

If I can find it....I bought one for the same thing about 6 years ago....
I'll look in the morning. I got in from Tool Center on 3rd west and about 15th south. I know it was under $20.

I bought a something/64's at CAL Ranch for my EGT probe, not sure if they have that size but they do at least have 64's IIRC it was $10ish for that bit.
