Ah. OK yeah thats not a spot weld removal bit but is what I referred at as a "regular bit". Meaning the shape of the point. In cobalt (looks nitrided too). Still works! I have a $9 set of nitrided step bits from HF that I've used for many years, those would work fine too. Heck I've used a plasma cutter to do it before, lol. Working in this spot, neatness isn't as important. Just need holes! Maybe our hero will get it whooped over the weekend...
