I used cutting oil,the bit stayed cool was not burned, still had good edge,
Yes I thought about a new larger drill impact driver, I posted here,
That and cobalt steel drill bits might do the job, it would also help of I weighted 200# and was 40yrs younger, at less than 130# squatting in a wheel well, it is difficult to maintain enough force to drill into this steel, not like standing at a work bench, where I could bear down on it, or use a drill press,
The amount of effort needed drill is difficult to apply, when your a "Feather weight" like me
This is case where Brawn is useful and needed,
If could borrow a small portable hand held laser drill I could do this project In no time flat
8 holes ....zap. Zap. Zap done
