Redrilling Wheels

So has anyone ever tried to redrill a wheel themselves? I have a set of wheels that is 5x112 and I want to make them 5x114.3. I know that machine shops usually do this type of work, but is there a drill bit I can buy to do this at home with a drill press?

LOL, I did not really think that it was a good idea or even possible but I was just asking. And as an FYI it is not for my M2.

Not worth it, you risk making the wheel worthless. A machinist probably wouldn't charge more than 150-200 bucks. It's not rocket science but it does require the proper tools and skill.

Anything is possible. Not exactly sure what you are trying to do based on your numbers. Appears you want to increase the center bore by 2.3 mm? If so you would need a boring bar with proper end cutter and a milling machine. Also would have to recut the mating chamfer on the ID side with another setup.

Doing this on a solid drill press with proper throw and set up would be shaky at best as you would still probably blow the tolerance.

Yeah, not the center bore of the wheel but of the lug holes

I wouldn’t do it myself... there’s a ton of machinist that will do it for you maybe $30 per wheel.

Agree with everyone, take to a specialist.
Cost is not worth the risk

Unless the wheels in question have a lot of extra beef/material in the center, I would not recommend doing this due to potential structural problems.

For what it's worth, properly "re-drilling" wheels to change the bolt pattern usually involves enlarging each lughole with the dead center of the new, larger cone shaped hole, centered within the desired new PCD. Once large enough, an insert with the lug seat is then pressed into this larger area to create a lugseat with the appropriate/desired PCD.

Here's a photo of a failed redrill. Notice the insert in-hand contains the lug seat. Now look at the wheel and notice the original lughole was drilled larger and centered with the desired PCD:



It was already answered by others but moral of the story? Leave this sort of thing to the pros. That said, 5x112 and 5x114.3 are VERY close to one another (so close you might even be able to slip a 5x112 wheel onto a 5x114.3 hub). If it does fit on, you may be able to use "wobble bolts" without changing the actual wheel PCD. Google this and you might find some info on VWVortex... Either way, personally I'd say a proper drill + insert by a pro is the only way to go and be safe about it.

Thanks for the info and the pics. Gonna wait till spring and give them a test fit and see where I stand.
