LUG STUD DRILL GUIDE
I made this drill guide to quickly center existing lug stud holes when upgrading to larger lug studs in axles. To begin, the round bar needs to be approximately 2″ long, and approximately 1/4″ larger in diameter than the drill bit’s size. Drill 1″deep into the short length of steel round bar. Taper the other end ~10 degrees. To use, slide the tool over the drill bit, then insert the tapered end into the existing hole to accurately center the drill bit.
