Re: Killer Drill Bit?
Yes, I always use a really small pilot bit, then work up in size when drilling metals. I did try that starting with a 1/16" LH bit, and stepped it up twice before I realized the bit had crept way off center due to the uneven plane and flex in a tiny bit. This hinge screw centering tool uses an 1/8" bit, so kind of a big for a pilot hole and tougher on a bit. I am concerned about using these hard McCallister-Carr bits with a hand-held drill. All I can do is try. I use a thread cutting oil when drilling steel but not much help here with drilling 'up'

Re: Killer Drill Bit?
You probably don't have stuff laying around to make a Mist coolant system.
This would be a lot of trouble for one bolt. I will just throw the Idea out there thou.
