[AT] Drill bits for drilling our old tractor steel and iron.

Speaking of drilling, I got this video from Sandvik on ‘drilling’ at an SKF plant in Mexico. Way cool to watch tho I don’t understand most of the Spanish parts.

Some rather large races.

The closest drill bits I have that I would call decent are a set of reverse direction drill bits made by Irwin that are Cobalt.  I’ve used them for removing broken off bolts, etc. but even those are not worth writing home about.  On grade 5 bolts they are ok but on really hard stuff they don’t cut the mustard. Cobalt drill bits do have a negative and that is they are very brittle. But…  what brand and version of drill bits have you guys found that are better than the average bear and work good on our old iron which seems harder than the current stuff. I’m fed up with my multiple indexes of drill bits that might work in wood if I was patient. On steel a nail might work better. :-) I know its going to cost and I’m prepared for that. What is the “Snap-On” of drill bits?  What have you had a long and successful relationship with.  However, I am convinced that no matter how good they are I will break anything less than 1/8”  So a set from 1/8 to ½” in 1/64th “  increments is about my style. Or as an alternative. What drill bit sharpener do you recommend? I do have a lot of drill bits that could be sharpened. Not sure some of them are worth it though.
