What size drill bit have people been using when drilling 6-lug wheels to Subaru's 4-lug pattern? I used a 35/64 bit, and I have a hard time getting the wheels back off the hub. I'd like to go to a bigger bit, but I don't know how big would be too big.

 

Thanks.

did you use a counter sink to match the bevel of the lug nut. i think its a 60 degree. you may want to ask scott in bellingham, he knows the size,

Are you sure your holes are in the right place? If they aren't and you keep making the holes bigger until they fit, then you'll end up with studs that are not centered in the hole which could be a problem.

use a 9/16 to drill wheels....

 

you use a 35/64ths to drill hubs......

 

and yes the bevel degree is 60 for the countersink,at least that is what i used.

Yeah, I feel pretty good about the holes being in the right place. The wheel just kept getting stuck taking it off last night. A slightly wider hole shouldn't be a problem, but I definitely don't want these things slipping off.

How about burrs, did you deburr the holes?

I didn't see this, that's your problem. Drill them out with a 9/16ths
