Hi, I need to enlarge the centre bore on my new wheels by 3mm. What type/shape of router bit would suit this job best?
Thanks.

How are you planning to do it with a router? What guides it?

It won't be precise, I know that.
I just need to wheel to sit flush with the hub so the wheel bolts can secure it to the hub.
The pcd for wheel and hub is the same.

Ideally it needs to be precise .
A little off & it can cause wheel vibration .

Won't the bolts centre the wheel though? Yes, provided it’s cut well enough to allow the nuts or bolts to centre the wheel. Obviously if the hole doesn’t end up central in the PCD then it could pull the wheel off-centre. |

Depends if the wheels are hub centred or lug centred and which the vehicle was designed for.

Should be fine being bolt-centric.  |

You need the type with the bearing on the end of the router bit to set the cut depth and follow the existing hole. You’re looking for a step between bearing and cutting edge of 1.5mm to give you a 3mm increase overall. A router is plenty accurate enough for this type of thing.

those look ideal, all the bearings are the same with a pressed on disc to make up the appropriate size so you could easily have one made/make one to suit.

I've done a few sets of wheels with a straight bit and a ring guide on a router. I made an mdf jig which bolted to the wheel holes. I have freehanded it too but you need a steady hand.
