swervey87gl Posted September 4, 2005 Share Posted September 4, 2005 Just got my mill working and wanted to know what size exactialy the wholes should be drilled for the 4 extra studs. I know someone has posted on here somewhere, what size to use. But I don't feel like searching through tons of threads to find it. So just a quick bit size and I will be on my way.

NorthWet Posted September 4, 2005 Share Posted September 4, 2005 I don't have an exact answer for you, but a suggestion on how to determine the right size. Use the shanks of your bits to see which one fits the whole in a suby wheel the best. Quote Link to comment Share on other sites More sharing options...
swervey87gl Posted September 4, 2005 Author Share Posted September 4, 2005 Yea I was thinking of that, I just wanted to be careful to get the right one. I could picture getting a flat in the middle of no where and have one lug spinning becaues I used the wrong size bit. I thought that the whole might be bigger from the stud bieng pressed in there. I don't know. Quote Link to comment Share on other sites More sharing options...
NorthWet Posted September 4, 2005 Share Posted September 4, 2005 Yes, the hole should be slightly larger than the stud going into it, and the conical lugnut seat (or whatever you use if you don't taper bore the hole) will cover a multitude of sins. But the standard for determining bit size (at least amongst non-pros ) is to slide the bit shank into an example/model hole. This is assuming that you aren't using reduced-shank bits. The proper bit should just barely move through the hole. Quote Link to comment Share on other sites More sharing options...
Qman Posted September 4, 2005 Share Posted September 4, 2005 He wants lug hole size, not the wheel hole size. I believe the easiest way is to buy the studs and determine the size from them. Yes, I have done this mod. One of the first to do it, actually. And yes, I am too lazy to go out to the garage and check the bit size.

So, if noone gets unlazy , you could press out one of the 2 studs that you need to do anyways, and use that hole as a gauge. Quote Link to comment Share on other sites More sharing options...

I would think this is the way to do it...since they have to come out anyway Quote Link to comment Share on other sites More sharing options...
