This may be a stupid question, but I'm trying to redrill my axle flange for the 5/8 stud. It has the standard size holes, so I am trying to enlarge them. I bought the drill bit from speedway. I am using a 1/2" Dewalt drill. It just seems like I am not making much progress. Is there some sort of trick to drill an axle? Or is it really a time consuming process?

If your drilling through the previous holes it should not be real hard. When I did mine I started a new pattern and it was a pain!

Purchase the same bit in a titanium and it will go right thur. Use oil and don't spin it to fast.

Thanks guys! I'm enlarging the previous holes on a stock axle. I have gotten three drilled out so far Two more to go. Just been drilling it slowly. Borrowed the drill from work. My cheapo 1/2 drill wouldnt cut it. I drill for awhile and then let everything cool (Dont want to burn up company drill). Going to get a titanium bit later for future use. It amazes me how easy these things get bent or broke, but it is a pain in the *** to drill

Try another bit I just drilled mine.Order 2 bits at the time one was taking me a hour a hole the other 5 minutes a hole. They must have some bad bits.

I bought a bit at Ace TrueValue it was cost more than the cheap-0s, but it has a lifetime warranty but has drilled many rotors, axles and lead chunks two years and going strong.

Finaly got them all drilled out with the same bit from Speedway Motors. Not really in a big hurry. We seem to get a lot of rain here on the Texas Gulf Coast on the weekends. Then the race gets rained out. Not really much races left. Hoping to get a couple races in before season ends. Thanks for the replys and advice. I should have went with my gut instinct and bought a good bit at the hardware I will now.

I use Dorman #610-163 1/2 - 20 studs on metric rear axles. I have never broken one and they are available at auto parts store, cheap, and just the right length. Plus only have to drill hole out to .532 so with a good bit it takes about 5 minutes per axle.
