Cheap bits? The good ones cost nearly 10x's as much at times but is worth it for some things.

Is that a smurf working on your rig?

They work alright. I'd prefer running 1/4 wave whips on the roof for each band, or something like the Comet SBB-5, or Diamond SG-7500
Unfortunately not cheap bits, Milwaukee Cobalts. I was able to weld up half of my bumper later in the evening though. I am going to have to buy replacement bits before I finish the other side.
I am. I'm using cutting oil. The problem I'm having is I'm drilling large holes with a hand drill, so the first bit I snapped was 1/4". I was drilling through 3/16" plate and while I was spraying more oil and only supporting the drill with one hand it started to punch through the back side, it caught in the hole, the drill twisted and the bit snapped. the second bit I snapped was because I knocked the drill off my work bench.
I use a hand drill for such things often, but it takes forever because I start small and progressively work up in but size. I end up drilling the same hole a half dozen times or more. You may be doing that too, in that case I've got nothing and it sucks you're breaking bits.

I do the same, I start small, work up. The drill I use has an optional second hand grip, if I use both it works better, also if I use a little slower speed it seems to catch less. The real difficulty came once I reached 1/2" size. Then I was drilling through the 3/16" plate spot welded to a 1/4" plate. The 1/4" plate had 3/16" holes drilled in it already, I was just enlarging it to 1/2" and making holes in the 3/16" plate at the same time. The biggest issue is probably I'm lack of patience.
