Hi guys, I'm looking to do this: YouTuber AndyDaviesByTheSea did it by grinding a broken 1/4" drill bit. I went that route, but it grabbed too much for my liking. And since I've made D bits in the past that worked well, I thought I could do similar for this. I took some 1/4" drill rod, faced it, and drilled the end 0.200". It's just a tube right now, but I'm thinking I can put the "D bit" angle on it? What do you think? It really only has to remove the top layer of copper (a few thou, I think). -Mike |

I'd think that you would need some "teeth" - just filed ought to work -russ |

Could you use a spot weld removing tool without the centering bit? |
| Mike K:
Yes, I know teeth, but I wasn't sure how best to do that. That EEVBLOG thread helps. Had considered a spot weld cutter, but OD and ID aren't what I want. I'll give cutting the teeth a try. I haven't done that before, it was why I asked. |
