This is my first post in the Shop Talk section so please go easy on me if this is posted out of turn. 
I just read Nathan the Machinist's thread and it was eye opening to me. Almost all of discussion after Nathan's first post was way over my head. But it got me thinking: Where can I get a good set of US made HSS bits? Or for that matter who makes good HSS bits? I am wanting to drill a hole in a steel liner to put in a stop pin and that is what got me searching for info on this. Also, a good tutorial on how to sharpen bits would be greatly appreciated. I am doing a search for drill bit sharpening on here as I type this.
