Hi everyone,
It's been awhile since I last posted! Anyway I am in the process of fitting some pug steel wheels to my audio 90. Have got spigot rings and centre caps and the wheels have been painted so they are ready to go on.
However there is a small issue in that the pug wheels have slightly smaller lug holes. They literally are only a mm or so smaller! Can get audi bolts through but only by winding it in. This is obviously going to damage the threads at best.
So how do I enlarge the holes? I did consider using a drill etc but largest drill bit is 12-13mm which is not large enough.
I could used a dremel etc but don't think that would be even enough!
Any help would be appreciated!
Cheers!

Take them down to your local machine shop and ask them to drill them slightly larger. They wont charge you more than say £30 to do them all

why don't you just buy a drill big enough to do it?

i wouldnt use a step drill unless you've a drill press to use them in. Either pop down an engineering firm or buy the dril (again id recommend using a drill press though)

Use a conical cutter rather than a stepped bit. It will self-centre on the original hole, where a stepped one will be hard to centre. I have a few of these and they are ideal for enlarging existing holes.....  |

Hi,
Thanks for the replies! They have been helpful, the main reason I didnt get a bigger drill bit is that none of the drills we have would have a large enough chuck so would need to buy a bigger chuck/drill which is a bit ott for one job.
I would take it to an engineering shop but I really don't have enough spare cash to do that.
However the conical cutter looks ideal, where would I get one of those? Are they expensive?
Thanks to everyone for the help so far.

you don't need to buy a bigger drill.
no drill bit has a shank bigger than 13mm(that youll be able to buy anyway), thats why all drills you can buy only have a chuck that goes up to that size. you can get drill bits for a standard 13mm chuck that go up to about 22mm. a 14mm one (which I'm guessing is what you need) will be about £6-7 from machine mart.

Known in the trade as 'Blacksmiths drills' Very often tho, the next prblem is getting the drill to turn slow enough for the larger radius drill bit |
