Hey guys,
I would appreciate a recommendation here. Do I want the zero angle type drill bits or the other style that is like a mini hole saw? Blair? I'll be working on a 04 honda civic si. Does this have the boron welds and if so would it not be difficult to position the "hole saw" type cutter exactly centered or do those cutters tackle the boron also? Any rec. where to purchase online also...thanks!

If ya are dong a quarter just get the Blair hole saw type. It will come with 3 cutters and should get a thru fine. Just center punch the spots first. Try autobodytomart.com
I get mine locally at the jobber.
Got this on my smart phone....

Good luck.

I've had good luck with a Blair spotweld cutter - I've only used the 'skip proof' variety but (so long as you center punch) it does tend to work as advertised. The Blair is a hole-saw type BTW.

Blair all the way, dont waste your time or money on HF. i have drilled about 200 holes in my Roadrunner and still unsing the same cutter.
OH, i also use the blair stick lube. one tube goes a really long way, and really makes a big difference.

I third the Blair. I was having issues with the bit skipping even though I center punched it. I'd recommend center punch, followed up by a tiny amount of drilling with your smallest bit.

I have found the blair tool to work best if you start out spinning the drill slowly until the cutter begins to make a groove. Once it has a track to follow you can increase the speed and pressure applied.
If you start too fast they tend to shatter on the spot weld high spots.

I used the blair for a long time and was never happy with it. So I tried the keysco




The 3/8" cutter was never very sharp, but the 1/4" did a good job for about 50 spots then the point broke off.
So I tried the Blair premium spot weld cutter, and it does a very good job. There is a pilot drill bit that is spring loaded and will not drill deeper than the cutter, but it doesn't need a center punch and doesn't walk around.







Just a good clean hole






Its very sharp, so you can use the drill at a slow speed and go right on through. And as Roadrunner said the Blair stick lube does help a lot.
