You need a 9/16" drill bit to open up the lug holes and a 60 degree
countersink bit to cut new conical lug seats. I did my Benz wheels about 4 years ago on
a drill press, you take off very little material when doing these mods. Both
cuts are self centering, so its pretty easy to do. I used standard 14-mm
conical chrome lug nuts that you can pick up at any FLAPS on my Camper, I used a
14-mm stud kit on the front rotors instead of using the lug bolts. I keep a set
of stock ball seat lugnuts in the Camper for the spare steel wheel.

The countersink bit should be available at any machine shop supply house, I
spent about $18.00 for mine. If you would like to borrow it, give me your
address and I will ship it to you. You can hang on to it and send it to the next
person that needs it.

Pay it forward.

Hi Tim & Thanks!,
I'm not crystal clear though, on the term "conical," that we are using here.
Are we saying, that this indicates a curved surface?
Or, does it just mean cone shaped, or (straight, (flat) ) Tapered?
In the machine shop jargon, we would just say tapered, unless there is a
radius involved?
Is it just a 60 degree tapered hole?
thanks,
John C...
